Noise cancellation - Off-topic

I have many questions related to noise cancellation but don't know where to go to get answers. Does anyone on this forum wish to offer informed opinions related to large-scale noise cancellation - or know of a website that deals with such matters?
Suppose a microphone was installed near a railroad track at a grade crossing and the sound of a passing train was picked up and phase inverted and then used to drive large speaker arrays at Db levels equal to the train's noise. Would such a system be feasible and if so, be cost-effective?
I live within 1/2 mile of such a track crossing and have to listen to about 70 freight trains every day and night. The RR company claims that building effective sound barriers would be far too expensive.
Any ideas?
Thanks,
Walt

In theory, active noise cancellation using phase-inverted sound can be effective, commonly used in headphones and smaller applications. However, implementing it on a large scale, like near a railroad track, poses challenges. Factors like speaker distance, precise timing, and sound control affect feasibility and effectiveness. Large-scale systems can be costly and may not always be the most cost-effective option.
While there isn't a dedicated website for large-scale noise cancellation, researching acoustics and consulting experts can provide valuable insights. Acoustic engineers or consultants experienced in noise mitigation can offer tailored advice.
Exploring alternatives like physical barriers or collaborating with local authorities and the railroad company for practical and cost-efficient noise reduction measures is worthwhile.
Remember, a comprehensive assessment and collaboration with acoustics professionals are key to finding the most effective and cost-efficient solution for your specific situation.

HTC BoomSound with Dolby Audio is noticeably better – Sprint Product Ambassadors

In the mobile tech wars between the multiple competing OEM’s, features and improvements have gradually shrunk in terms of their impact and the overall change to the user experience. Certainly with regards to improving features that have long been a part of mobile phone technology, it’s been more difficult to really differentiate certain features much more.
However…
HTC’s BoomSound is the exception. There are times when you see, or feel, or hear a significant difference on newly released devices that truly stands out. For me, BoomSound has been a differentiator. I’ve had the opportunity to use other flagship devices that have been released this spring and summer, and when I put on my headphones to listen to music for the first time on the HTC 10, I actually stopped in my tracks and said out loud, “Wow. That sounds WAY better than the others…”
Now… some would say that’s because I was using the Harman Kardon NC buds, and quite honestly I think that has a lot to do with it. HTC’s BoomSound with Dolby Audio is designed to not only enhance high and low tones, but also works extraordinarily well to complement high end cabled headphones and speakers. There are options to use three different types of HTC headsets, as well as the “Other” option for headsets or speakers that don’t fit the HTC earbuds, HTC in-ear, and HTC Pro Studio options.
I have been using the HTC in-ear option with the HK buds. I feel like the music really lit up, and even more so when I used the powered Noise Cancellation feature on my headset. I have even tried tinkering with different sound features on Spotify, YouTube, Tune-In, and other media players on the device, and for every single app, the performance has been extraordinary. In my humble opinion, the audio performance for the HTC 10 is the best out of the 3 recently released flagship Android devices.
I should also take this opportunity to talk a bit about HTC accessories. I was able to use a set of HTC earbuds that came with another device a few generations back. Unfortunately, after one of my workouts, I left the earbuds in my pocket, and they went through a full cycle in the wash that included a 30 minute pre-soak and then a double rinse cycle. That was a month ago, but the earbuds still work today. I don’t recommend washing them or immersing them in water. As a matter of fact, my advice is that you should NOT get them wet. However, I think it’s a testament to the build quality of HTC’s hardware and accessories, and in the context of this blog, their AUDIO accessories that a set of earbuds did NOT fail after being fully washed.
Since HTC initially released the HTC One with HK audio tuning, I think they’ve continually worked to balance cost with performance. I feel like with the HTC 10, they hit the nail on the head and have built an extraordinary device for music and media enjoyment. I also HIGHLY recommend complementing your HTC 10 with a set of Earbuds, In-Ear headphones, or Pro Studio headsets. If you love music and high quality audio, you will be doing yourself a favor by picking up a set of good headphones to use with the HTC 10.

If money is no concern, which should I buy?

I'm either wanting an Android Auto head unit, or a full android one. There are a lot out there, all with mixed reviews. So which is the best one?
For full android head units, I did *alot* of reading and searching before buying. From what I can tell there are no super high quality android headunit from big name companies like you have with phones. Alot of it depends on what is important to you.
Your not going to find a unit perfect unit out of the box. There are some good units out there but all seem to require rolling up your sleeves, researching threads here, and having the technical ability to make it work for you. That's what's great about android, but can also be a big downside to a non-technical person.
I bought a Joying 2gb / sofia unit. It does have a couple of rough spots out of the box, but with the help of people here all of my issues have been resolved. Hardware wise, it is a very solid unit with good display, nice feature set, decent sound quality & performance. Their latest update resolved all of my bluetooth issues, which was my biggest complaint. I wouldn't even consider a 1GB unit with google bloat in their apps lately.
It's not the latest high power CPU but works well for it's intended use. It runs torque, maps, pandora, and a few other apps constantly and is still very responsive. It based on ASOP 5.1.1 / lollipop, very stable and never had an app force close in over a month of use.

Is that one easy to install the google framework, and all on? If I got a full android one, I'd want to be able to watch youtube. That's pretty much my only reason for considering them
Just install from play store. Framework and store already installed out of the box.

So would you recommend this over an Android Auto radio, such as the new one by Sony? Do you think the quality of it is good enough to last a year, or longer?
What are your goals here? Are you looking for a full Android experience, or Android Auto only?
For Android Auto alone, I'd recommend any major brand's Android Auto compatible units as they will be higher quality, with better sound and better warranties.
If you want a combo of the two, Pioneer's NEX units are Android Auto compatible, but they also support AppRadio mode. Rooting your phone and using AR Unchained Reloaded will give you the fill Android experience using your phone and a wireless display adaptor.
Just the full Android experience, but not too worried about possible bugs, sound quality issues or support, one of the units recommended above will work.
I personally use an AVH-4200NEX from Pioneer for Android Auto. I replaced an old AppRadio 2 with this unit and have yet to use the AppRadio mode even once.

I don't know which I want, which is why I am reaching out to you guys. I like the Idea of the full Android head units, but don't know which are good or reliable. I also like the idea of the AA units, and am considering the new Sony one, or possibly the AVH-4200NEX.
I think I'm kinda leaning towards the full android unit. I usually download music videos with my youtube red account, and use that for listening in the car. This way I wouldn't have to use my phone. I just worry about it not sounding nearly as good as a normal radio.

Sound quality is a very subjective and debatable topic. But I'll throw in my 2 cents.
First, consider your probably listening to compressed music, in a noisy environment. In a home audio system in a quiet room at normal listening levels, *most* people cannot hear the difference between a system with 70db s/n vs 90db s/n.
In a car, the difference between the stereo and "road noise" ratio my be 30-50db at normal listening volumes. My 'cheaper' android head unit claims a 90db s/n. Even if this is exaggerated, the road noise is 100x greater than noise introduced by the unit. People also claim they can hear the difference between a more expensive DAC, which is also debatable. Compressing music ( even at higher bitrates ) introduces far more distortion and artifacts than almost any modern DAC. If your going over bluetooth, that in itself can reduce the quality by a very noticeable level.
I'm very happy with the sound quality of my 'cheaper' android unit, but I am not what you would consider an audiophile.

So if I did go with one, would this one be the best as of right now? https://www.amazon.com/dp/B01M670UW...UTF8&colid=2QPCTDNBY3GCZ&coliid=IZMEX683T5VOE
Do you know if it has separate sub controls? I have seen that some of the android units do, and some do not

MDR-1000X or WH-H900N? What's your flavour?

As many of you know Sony has a pretty good offer on pre-ordering a Xperia XZ1 or XZ1 compact. You'll get a free Sony NC headphone!
There is only one dilemma, they offer two types;
The MDR-1000x
https://www.sony.com/electronics/headband-headphones/mdr-1000x/specifications
and the WH-H900N
https://www.sony.com/electronics/headband-headphones/wh-h900n/specifications
The MDR-1000X was voted one of the best NC headphones of 2016 but is an old model. The WH-H900N is a lot newer so there are not a lot of reviews to compare it with the MDR-1000X(so I have no idea if it's any good)
So I was wondering: What headphone are you guys going to choose and why?
Are there any places that are offering this pre-order bonus still? I can't seem to find it, the closest thing I see is by Clove UK which is giving away the SBH24 Bluetooth Headphones.
My research so far resulted in this list of points in favor of the 1000x, when compared to the 100ABN (h.ear on wireless 1):
- subjectively better sound quality
- better noise cancellation
- more comfortable on the head (again, subjectively)
- hard carrying case (instead of a pouch)
- less issues with wind sounds amplified through the mics
Things that are in favor of the H900N:
- probably more responsive touch controls
- less issues with phone calls (mic related)
- sony headphones connect app support
- presumably no headband issues with the 100ABN
- longer battery life (and quick charge support)
- more recent model
But again, this is mostly when compared to the 100ABN; the H900N might just have improved sound quality and/or noise cancellation... let me know if you find any reviews!
I haven't seen that offer on the Compact in the UK. Best offer I've seen was the Clove one with the bluetooth adapter - which what I opted for.
For the XZ1 too, the headphones were limited to the first 400 users to complete a successful claim. Sounded too much like a gamble to me.
I've got some Sennheiser earphones at the moment, but am tempted by a pair of cheap Sony noise-cancelling headphones to go with the bluetooth adapter instead. Drown out some office noise etc.
found this WH-H800 review with some WH-H900N references:
https://nerdtechy.com/sony-wh-h800-h-ear-2-mini-wireless-ear-headphones-review
I was googling for an answer to this question, which is how I ended up here.
So I searched a bit further. My guess is: the WH-H900N is only a year younger (I think) than the MDR-1000X. What is more, The MDR-1000X is last year's top-model and its successor is the WH-1000XM2, not the WH-H900N.
The MDR-1000X had excellent sound quality and great reviews. Sound quality isn't a technology with huge developments, so I think purely sound-wise, the MDR-1000X is probably still better than the WH-H900N with only a year between them.
It also looks a fair bit beefier. Possibly better padding on the earcups; I read it's still very comfortable with glasses.
The WH-H900N does seem to look a bit sleeker and comes in a variety of colours. Maybe a bit more fashionable.
This year's models also come with fast-charge (65 minutes playing after 10 minutes charging) so that's in favour of the WH-H900N. The WH-H900N also has 6 hours more playtime when fully charged.
So MDR1000X seems to have some disadvantages and some (possible) advantages over the WH-H900N. If I'd had to choose right now I'd say MDR1000X, but I'm going to check on the tech issues mentioned above by sssparkkk first.
It's a pretty sweet deal though, whichever you choose!
- edit - checking some reviews on amazon.com and amazon.de (3 stars and below) I read that multiple users have issues with the headband, and other breakage issues. So maybe the WH-H900N after all..
I've ordered the black WH-H900H today. Will write a review when it arrives
The way I see it is that the MDR-1000X is last years top model of Sony, where the WH-H900N is a segment lower. I have compared the MDR-1000X and the H900N's predecessor MDR-100ABN in the store. The 1000X was lighter, had a much better fit and its ANC was clearly of a higher level. The 100ABN was sturdier though, probably can handle more clumsiness. The H900N still has somewhat the same design, making me believe the 1000X still has an advantage there. Also the ANC works better with the earpad design of the 1000X.
Looking at other specs and features they are almost the same. Here are some differences:
The H900N has a better battery life (28 hours), however I think 20 hours of the 1000X is also plenty enough. This is of course a personal choice.
The H900N probably also has a better touch control system, and maybe some more options with a connected mobile app. This I haven't checked.
The 1000X on the other hand has a wider sound spectrum, giving it a more clearer and nicer sound.
The 1000X also has this really nice feature that the ANC adjusts itself to the shape of your head.
So, if you want to be sure you have top notch headphones with probably the best sound quality and definitely the best ANC, go for the 1000X
If you want to have headphones that are a bit more sturdy and have the newest (secondary) features like the application with all its options, go for the H900N
Curious whether you guys agree!
I've got the 100ABNs and am wondering about upgrading to the WH-H900N but I don't really see any reason to do it for touch controls and more codecs. Unless the ANC has improved I'll probably stay on the 100ABNs.
Interesting.
Here, they only offer 3500 headphones for those who register after preordering.
One of the issues surrounding the 1000x, and its upgraded version, is that noise cancellation turns off after 5 minutes unless it is paired or has an audio jack plugged in. Kind of makes it a strange noise cancellation accessory.
I did not buy the 1000x, it has problems in the headband, they break near the hinge. Prefer the new version 1000xM2 that in theory, does not present that construction failure. Greetings.
I own the sony 1000x, great sounding headphones. My one complaint is phone calls the mic picks up to much external noise to make it usable. I would like to think this has been improved given this is one of sony's better nc wireless headphones.
When I was buying headphones I tried WH-H900N and MDR-1000X. After a mounth of calculating I decided that MDR-1000X has better sound quality. Decision was a half good because my MDR-1000X broke after 6 months of use. I don't know if Sony fixed this on newer series of MDR-1000X. MDR-1000X has excellent sound quality but poor build quality. On the other hand WH-900N has better build quality but not good sound quality as MDR-1000X although they have dedicated android app for better sound.
Two months ago I bought MDR-1000XM2 and concluded my searching for now.
WH-H900N vs MDR-1000X vs WH-1000XM2
I initially purchased the H900N, but quickly concluded that the sound quality, even using the cable, was pretty poor even compared to my old $35 Sennheisers from 10 years ago. Before sending the H900N back, I did a sound comparison between the H900N, my old Sennheiser HD212, and a friend's 1000X, with all the features turned off on both the Sony's (i.e. power off, cable plugged in so as to purely compare the quality of the cones, without in-built software messing around with the sound). The H900N sounded lifeless, muffled, lacked fidelity, and made everything sound dull. The 1000X sounded a million times better, much more life-like in the sound, and just sounded great. I then spent ages swapping back and forth between the Sennheisers and the 1000X and concluded the probably sounded better on the 1000X, but my ears are so tuned into the Sennheisers after many years it's probably difficult to tell. However, when I then turned on noise cancelling, the 1000X smashed the Sennheiser out if the park, it just sounded fantastic, and the ability to drown out background noise meant I was able to here so much more detail even at very low music levels.
I can only conclude that the H900N are a low quality headphone but with all the bells and whistles. They're great if you want some well-made noise cancelling headphones, but the audio quality is inferior to even cheap wired headphones, so avoid if you're even slightly an audiophile.
I sent the H900N straight back, and purchased the Sony WH-1000XM2. I did weigh up getting the original 1000X (cheaper, same price as H900N), but was keen to have AptX-HD (which was the original reason I chose the H900N over other brands) so went for the pricier M2. The 1000XM2 is so much more of a premium product than the 900, they sound so much better, the noise cancelling on them is fantastic, bluetooth streaming over AptX HD sounds great, they feel sturdy and comfortable to wear, and they come with a proper case (unlike the H900N which comes with a flimsy soft case). Not looked back since!!

Question Buds or Wired Earphones

Curious what users are doing for audio. Wired eaphone options are pretty thin if you're connecting via USB but they provide the range that Bluetooth can't match. I've had mixed results, what's your take?

I am only using Buds series for a while as they came free with the S-series in Australia when pre-ordered. Very convenient.
Buds+ you need a set if for nothing other than phone calls. That's all I use on my 10+
Using the c port for audio output all the time is going to screw up cables and maybe the port it's self. Tell Samsung to not jack off

1. I use a USB C to 3.5mm convertor and good wired haedphones (with a wider soundstage and instrument separation) for immersive listening at home (usually in the eveing after dinner, before I go to bed). I use the dongle mainly becasue I already have wired headphones that I don't want collecting dust - and I don't want to spend a lot on larger wireless headphones when a relatively cheap adapter can do the same thing for me.
2. Galaxy Buds live for use during the workday for calls and casual music streaming while going running in the morning, or other outdoor activity. Very comfortable for long use, strong reliable connection and good mic quality for phone calls. Easy to carry around without a tangle of wires.
If I did not have a pre-existing collection of earphones, and was given a gun-to-the-head choice of just one device, I'd choose the wireless earbuds over the wired ones, simply because it fits my needs the best. YMMV.
The big Buds+ thread:
Galaxy Buds, Buds+ Set up
Install the Galaxy Wearable and Galaxy Buds software. Update software and Buds firmware, this is important because the old versions sound sucks. Turn on/go to Developer Options in Settings and on the Bluetooth Codec setting toggle on Samsung's...
forum.xda-developers.com
I haven't used to Buds Pro so I can't comment on them but their body is a different design from the Buds and Buds+. The Pros may not stay in as well though.
The Buds/Buds+ are identical dimension wise.
The wings and ear pieces are interchangeable between these two models.
They don't fall out, ever. For calls you can put them in loosely and they still stay put. The Buds+ bring longer battery life (very long) and better sound Q than the Buds, I have both.
With respect to audio listening devices I'm compelled more towards sound quality than convenience. Buds are developing as the market grows with improved acoustic profiles and software integration for codecs. They also provide a higher flexibility for physical variations like exercise and two way communications.
The biggest drawbacks are the diminished range of audio signals, reliance on the Bluetooth subsystems and charging metrics. In my youth and midlife I spent years in a variety of bands. Rock, alternative, blues, techno and even country. Lots of nights preforming live gigs and even more time in studio sessions. As a result my listening skills are pretty well developed.
Not a big believer in high priced units knowing a $50 set can put a pair of $300 sennheisers to shame. When I surrendered my S10 Plus to my wife I started researching wired units with USB Type C Connectors. Dongles while useful for retaining a good 3.5 jack unit are just another link in the chain so I've dismissed them.
What I've found is there isn't much to chose from, just a handful. Much to my dismay 1MORE Quad Driver, which offers pristine audio quality have yet to expand beyond it's 3.5 jack. So I settled on the next best option which had to deliver a solid bottom and midranges, which most units lack, they're too tinny and treble focused.
In the interim I found a decent set of Samsung/AKG Type C noise cancelling earphones. They no longer manufacture them but a few sellers in South Korea still stock the item. Not expensive at $70 USD and the sound quality is a solid 8 on a scale to 10. Strong response in all ranges and very comfortable in my ears, YMMV. Another plus is the noise cancelling doesn't sap a lot of power which can lead to reduced volume. In conjunction with Poweramp and some solid tunes, life is good!

Poweramp... whatever earphones or buds you use, use Poweramp to dial them in. I would hate my Buds without it for listening to music.
It's graphic equalizer is second to none.
Poweramp has a steep learning curve but is extremely configurable. Applicable only if you have a music database.

One badass feature Poweramp has which other platforms lack is the preamp slider which actuates as a great gain function, it's versatility second to none.
Guys aren't you a little concerned about the safety of the TrueWireless (TW) buds? I mean, the fact that they have a direct wireless connection passing directly trough your brain, doesn't feels a bit weird.. Something about it seems fishy to me when I think of limiting radiation exposure.
I use Bluetooth headphones where the BT receiver is under my neck. The cable is separately connected to the KZ ZS6 which have 4 speakers in each headphone. The sound is out of this world.
Most buds employ direct wireless connectivity. Does the BT signal cause damage to the brain? Ask an ENT Specialist but the buds don't transmit BT, they recieve it. Excess volume is the number one harmful side effect in near tympanic audio signals. My question is if you're going to use a wired connection in your BT configuration, why not use wired earphones? The audio quality is superior and you won't need to worry about BT scrambling your brain.

Well actually the wired vs wireless quality is not something to even discuss. The above headphones I mentioned, eat any other headphones I have ever tried for breakfast when it comes to quality.
The buds do receive and emit BT and it is happening right next your ears. The bigger issue I mean is that the 2 TW headphones are directly communicating with each other trough some sort of electromagnetic connection that I had never heard of until I googled "how do True Wireless headphones work." That direct connection is not BT and it is emitting and receiving at the same time, directly trough your brain... You feel me?
No one is talking about that and no one is assuring us it is safe. It is almost as if it is magic and no one should be even thinking of it.
The BT headphones with a cable that I showed above, have their BT antenna in the little black thingy you see on the pic, it is usually hanging under my neck, which is at least 20+cm from my brain.
I am aware we cannot fully escape radiation but we could at least try to limit the artificial type a little bit when we can. Just my 2 cents.
Yeah the massive amounts EM radiation that Nicola Tesla subjected himself to killed him at the early age of 86
If a little low energy EM is all it takes to TKO today's whatevers... good luck with the hard stuff.

Near Field Magnetic Induction (NFMI) is the wave you're concerned with, not the BT wave. It's been around a lot longer than BT, first used in hearing aids decades ago. Can't say if it's harmful but I'm sure studies have been done. You really like your setup, whatever works for you but I won't agree sound quality is capable of matching a good wired set. BT doesn't have the range wired sets offer, regardless of how you tweak the codecs, the conductivity is inherently deficient.
I have a pair of Shure se846 earbuds that I connect via the Shure USB/DAC cable and it sounds absolutely fabulous when listening to anything CD quality and above. For convenience sake however, I use the Sony WF 1000XM4s and they sound really just as good. Especially with the LDAC codec.

The biggest problem with S21 Ultra Codecs is they squashed aptX Adaptive, aptX Low Latency and aptX HD even though the Snap 888 SoC supports it. The reason, they're pushing their own Scalable Codec, Galaxy Buds and they don't want to pay Qualcomm's licensing fees. The aptX Codec available on the device is an older, vanilla version, not much different than SBC. Cheap bastards!

You got LDAC and SSC. Get the Buds+ and be happy. I'm using them right now, been using them for the last couple hours... their battery life is really long and they sound good. They link up seamlessly with a Samsung phone. Samsung actually got it near perfect... finally
Or jump ship to the newest Sony with the codecs you want plus a 3.5 mm jack.
Given a choice I'll take a vinyl over a cd or anything digital every day of the week. Why, because it's direct sound, BT just gets in the way. The Samsung/AKG ANC's are dirt cheap with great response throughout the entire range.
Was listening to some old tunes, The Best of Simple Minds. What separates them from others is their dynamic composition and arrangement. As a musician when I listen to a song, I feel the song as a whole, but I'm paying much closer attention to each of the individual instruments. When you can hear the sound of the guitar pick hitting strings, not the reverberation of strings, the click of the pick, your know your audio signal is tight.
When I upgrade it's going to be wired with 4 drivers, likely the 1More Quad Driver, may have to deal with a dongle. There's virtually zero overlap of frequencies. Put that set in your ears and you'll throw rocks at any BT device on the planet.

Yeah, I totally agree there. Don't know why they did this but at least I can use LDAC and it sounds even better than aptX
Buds+ is mandatory for a Samsung phone if for nothing other than calls. Music sounds pretty good using SSC.
Now the real bad news...
No sealed system can faithfully reproduce the sound stage. You must have a minimum of 2 stereo open air speakers*. The stereo (or more) acoustic waves need open air to interact with one another to reproduce the sound stage. This is what creates the electronically coupled sound stage ie where it was recorded to your listening area.
Headsets and earbuds destroy the sound stage.
Even DTS and Dolby headphone solutions don't come close to the complex sound stage an open air system reproduces.
Read it and weep ( you will when you hear the difference).
*minimum 12 - 50,000+ hz frequency response for optimum sound stage
