Sound Isolation & Noise Cancelation Technology

hello!!
i am worried about my ears!
the ringing sound on my head is growing so i decide to buy
some noise canceling headphones to reduce loud music when i work but also protect my self from other ones as well.
i Bought the Bose noise comfort 3. And it amazing what happen when you turn them on. It makes you feel like you under water!
but after a while i start yo feel weird…
is there any possibility that this is causing more problems in the end?

Thanks in Advance!

Most people who have no idea about noise cancelling earphones say that it damages your ear. THIS ISN’T TRUE. You’ll find that because it cancels out outside noise so you can play music at a lower volume to feel satisfied, thus reducing the actual noise your ear’s have to take in.

Think of it like this, if your driving a loud sports car, you’d have to play your music very loud to be able to have a good listening experience, whereas if you played it when inside an isolated bedroom you’d only have to volume very low. The lower volume saves your ears.

I also have the ear ringing sound your experiencing (aint it painful! lol). Its not because of the music but probably because your removing too much ear wax! Try to lay off the ear buds LOL! When I was about 18 the ringing sound was horrible (especially when on the phone) and lasted till I was 20. My doctor said that it’ll slowly go away when I stop drying my ear canal after showers – however expect it to last for 2 years or so.

Going on a couple really long flights in the near future…..
Engine noise is brutal when trying to sleep.

I use the Bose Quiet Comfort 2 over-the-ear. There are two kinds of noise cancelling headphones.

The first kind just pipes in white noise. White noise is random noise kind of like radio static. It cancels out a lot of the background noise on planes.

The Bose however actually have little microphones on them that "hear" the background noise and then create an inverse sound wave, effectively cancelling the background noise. This way is much more effective and quieter than the white noise way.

There are other noise cancelling headphones than the Bose that work this way as well. Just make sure that you get the ones that cancel the noise and not the ones that pipe in white noise. You’ll pay more for them, but you’ll be glad you did.

Enjoy your flight.

It seems like since noise canceling is just a mic and chip that puts out the oppiste signal to your headphones, couldn’t there be some sort of program for the computer that would do the same thing with a regular mic and headphones?
That’s to mute the speakers. I’m not trying to turn of the sound that’s playing (like my music) I’m trying to mute everyhtign BUT that that is going on in the environment around me (E.G. I sit in a room witht h eTV on and I want to block out the TV noise similar to how noise canceling headphones do, but with software) The prblem is I’m not sure if this is even possible, sinc ehte computers response would have to be instintanious. Otherwise even half asecond delay would be too late.

Most computers already have a function to do a noise cancelling. Double click on the small speaker icon that should show in the bottom right corner of your screen near the clock display. Check the settings there on the mic and the speakers. Depending on the audio programming, you may have a standard mute command, or other commands to do the noise cancelling.
Good luck.

Are noise canceling headphones effectives on airlines? Many of these headphones are advertised to be used on planes, but is the level of noise that annoying to make one of these gadgets a good purchase?

Would not travel without them, I tried the cheap ones but if you can afford the Bose Quiet Comfort they are the best on long trips. They have a cup over the ear design which means the headphone does not sit on top of the ear but rather around the ear, this makes them more comfortable.

I will use them for music as well, but I mostly want them to cancel all the distracting noises around me.

I am willing to pay 100-200 dollars or so, but if there exists a pair that will do an amazing job and is cheap, awesome!

Bose is highly recommended I hear.

I have not found any head phones that screen out all noise completely. The way I have found that works can be done with any head phones and a tape recorder. Connect the head phones to the recorder. Do not put a tape in it. Instead turn the volume up to a moderate level with no tape in it. This will create "white noise" that will block out all outside sounds. Another thing to do is to maybe just go to a library or some other quiet place because it sounds like maybe you can’t get rid of the noise -it is coming from people who will not leave or outside noises.

Lately i’ve been saving some money to get a nice or even the best head/earphones I could find. Now I can’t decide between these 3, all expensive but the sony and bose is noise canceling, while the Shure is sound isolating. Sony is over the ear, Bose is on-ear, Shure is in-ear. PLEASE HELP!

Well, I like using the best things in life. Off course not to the level of extravagancy, still i would say that it all depends upon ones own passion and level of understanding the beauty underneath. Too philosophical that was…….

Anyways its not only you who got confused in this selection, I already have spent good time now in understanding the crux. I appreciate your concern.

Bose QC3 = Sennhieser PXC450, both are good but specifically been made keeping in the mind the frequent travelers. I have tried both but not get happy with the results. Bose QC3 looks cool while wearing and will be best for anyone who get easily satisfied with the added punch and treble in the song. But think it like, Do you really need that much of isolation from outside noise, specially if you spend some parts of your day in quiet env., coz they are nothing but mere over publicize products. They both basically don’t concentrate upon the best quality sound, but on cutting the outside noise.

Shure SE530 = Sennheiser IE8, both good but shure se530 definitely is the one that gives the most decent quality of music to your ears till date. And on that they both cut the outside noise remarkably, without electrical circuitry like in case of Bose QC3 or Sennheiser Pxc450.

If you like listening your music in its purest form, without creating much fuss around then shure se530 pth is the best choice, else Bose Qc3 is good as well……… cool looks.

I am moving in with a drummer and I expect that there will be lots of times when he is practicing and I want quiet. I was thinking of investing in noise canceling head-phones, but searching over the internet is proving to be tiresome. Does anyone have any advice on noise-canceling headphones? How well do they work? Do I have to be playing music on them or can I just have the sound of silence? Any advice or reviews is much appreciated. Thanks!

Noise cancelling technology works for continuous sound, such as the hum of an air conditioner. But more dynamic sound such as a voice, or perhaps your roommate’s drums will not be effectively cancelled out.

The reason for this is because the technology has a microphone which picks up the outside noise, reverses the phase, and then generates the reverse wave. The original sound wave and the reversed wave will essentially cancel out each other and you won’t hear anything.

I am looking for headphones to block out a very loud ventilation system for a research study. I will need to communicate with the person wearing the headphones. I can either have a microphone set up to the headphones (I will be in the next room so we can be connected via cord), or I can record it ahead of time and play it back through the headphones. Does anyone have any suggestions for headphones that 1) cancel low background noise, and 2) have decent sound quality for talking (music is not important). Thanks!

The pioneer headphones are what you need. It’s designed to cancel out sounds for times like when your listening to music on an airplane. If you turn the volume right down I belive you can hear other people calling you. Search for it on amazon or pionner.co.uk.

By the way you will lose concentration if you are working while listening to music. Get earplugs instead because they can cancel out some noise and will help you concentrate more.

Can you listen for a long time with the active noise canceling on without any damage to your ears? A friend says that the noise canceling function is harmful if you leave it on your ears too long.

No there is no risk. I’m sure of that.

But I would recommend noise blocking (such as Shure) instead of noise cancelling. The Noise cancelling will block the lower constant frequencies, but higher, frequently changing ones it can’t. So for commuting for example you are much better off with noise blocking

In the United States, Bluetooth gets absolutely no respect. It is however, becoming more and more common in notebooks, PDAs, and especially cell phones. Bluetooth will provide wireless users a way to transmit small amounts of data over short distances.

Now, Bluetooth is facing stiff competition from new wireless technology. Referred to as UWB or Ultra Wideband, it promises data transfer of up to 480 MB a second – while most current Bluetooth devices transfer data up to 721 KB a second.

For the time being, Bluetooth devices are surely cropping up. Below, we will look at some of the accessories offered with Bluetooth technology.

Talking to the dashboard

When pairing it with a cell phone, the CCM Blue Warrior car kit becomes a great speaker phone that plugs into the power adapter of your vehicle. The noise canceling microphone will reduce background noise efficiently, with the large buttons making adjusting the speaker volume a snap. Although the Blue Warrior is far from sexy or sleek, it’s very practical.

Tiny tuning box

Part MP3 player and part hands free phone, the compact and lightweight Sony HBM-30 is an attractive gadget that lets you accept calls with minimal interruption of your tunes. When you get an incoming call it will automatically pause your music, then you speak into the built in microphone that you can wear around your neck or clip to your clothes.

The pen

With Nokia’s SU-1B digital pen, you can doodle and make hand written notes in ink on a special pad then transmit them from the pad to your Bluetooth phone. Being an alternative to typing on a cell phone keypad, the pen is very handy, although a pricey tool from MMS fans.

Snapshots

If you want to make slide shows with your camera photos, the Nokia SU-2 image viewer will let you display your pictures on a TV or projector. Simply hook this square gray device to your TV’s input with the built in cable, and then beam the pictures to the SU-2 from your Bluetooth enabled phone and the photo fest will begin.

This device is a snap to set up and use, although it displays resolutions of up to 640 by 480. If you have a newer phone that takes high resolution photos, you won’t be able to use the Nokia SU-2 image viewer.

Keep in mind, the 640 by 480 pixel photos will appear blocky on TV screens, no matter what you do. If your phone can send batches of photos, you can create a slide show – although Nokia claims you can use sequentially beamed shots as well.
