Sound Isolation & Noise Cancelation Technology

Well Im getting a ipod touch soon and i need some good ear phones with great quality not those crappy apple headsets.Anyways i stumbled on these two headsets which many people say are great. I ant the headset to be clear and have alot of bass i also want the headset to isolate noise 4 when im at school.I want it to have great quality.

if you’re looking for bass then for sure you should get bose. it says it in it’s name lol. trust me , i own a ipod touch and the bose in ear headset and its great. you could really hear the bass!!!! and the best part about the boss is that its quiet. unlike any other headset if u pump up the volume to max everyone around wouldnt hear the noise. so u dont have to worry about volume control at a room or around people.

"you get what you pay"

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.

The invention of the mp3 player has changed the way we listen to music. Never before have you been able to take your music with you as easily as you can with a small portable mp3 player. These wonderful gadgets can be made even better with the proper accessories.

Because of the huge amount of popularity mp3 players have there has been many new accessories made available for your mp3 player. You can buy almost anything for your mp3 player from external speakers to fancy remote controls. Because of the competition these accessories can usually be found at a fair price and they will greatly add to the usefulness of your mp3 player.

The main thing the iPod and the other players are about is sound. This article will look at upgrading your stock earbuds to improve the sound of your player with the best headphones for your mp3 player.

The most important upgrade you can do for yourself is to purchase a set of quality earphones. The first time you put the better set on your head you will be overwhelmed at the difference in sound quality.

The earphones that come with your mp3 player may or may not be sufficient for your needs. Depending on how sensitive your ear is will depend on whether the stock earbuds are adequate. Some people cannot hear a lot of difference in stock earphones and the better aftermarket varieties. One thing is for sure; a lot of people will want to upgrade their headset for a better sounding pair.

The first thing to think about is how comfortable are your earbuds. If they are a hassle to wear you will not like them no matter how they sound. Look for a set of earbuds made with the foam that is soft and will expand. These seem top fit most peoples ear the best and do a great job of blocking out external sounds.

When you are deciding how good a sound you want out of your phones you need to remember generally the more you pay the better they will sound. You can get some pretty decent starter types of earbuds at your local department store.

The high-end models normally start at around a hundred dollars and go up from there. If you are a serious audiophile you will want to purchase a quality set that will run you a few hundred bucks. This will be a set of earphones that would satisfy the most demanding audio lover.

The portable mp3 player is here to stay and improving the sound with the best headphones for your mp3 player is usually the very first upgrade you should consider. You will be amazed at the results.

im looking for a good pair of sound isolating earphones that have a nice bass quality and little interference from outside noise as well as noise caused by moving the wires. any suggestions?

The V-Moda Bass Freq Noiseisolating Earphones with extended bass, they are around $40 to $50 Dollars. Have crazy amounts of bass and will blow you away. If you dont like so much bass try the Shure E2g they around $60 to $80 and have better sound quality

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

Put on these Bose headphones at the apple store and clicked a song and they had it up full volume – turned it right down, but for a second there it was pretty darn loud.
got a little ringing now, seems kind of muffled.

Here is a rule of thumb for permanent hearing loss vs exposure time:

85db = 8 hours
88db = 4 hours
91db = 2 hours
94db = 1 hours
97db = 30 minutes
100db = 15 minutes
103db = 7.5 minutes
106db = 3.8 minutes
109db = 1.9 minutes
112db = 1 minute
115db = 30 seconds
118db = 15 seconds
121db = 7.5 seconds
124db = 3.8 seconds
127db = 1.9 seconds
130db = 1 second
133db = 1/2 second
136db = 1/4 second
139db = 1/8 second
142db= 1/16 second

http://www.dangerousdecibels.org/hearingloss.cfm
Ringing is not good. It is an indication that some damage has occurred. If you are exposed to extended periods of high volume, you first lose your ability to hear higher frequencies.

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.

With audio and video gear taking center stage in many households, it’s bound to happen: You’re relaxing to a classical CD when your kids start blasting MTV or a DVD movie. Rather than resorting to a duel of decibels, you can keep the peace by doling out headphones.

WHAT’S AVAILABLE

There are a few hundred different headphone models on the market. Sony is the market leader; other leading brands include Aiwa, Jensen, Koss, Panasonic, and Radio Shack.

Home/studio. Most look like earmuffs, with earpieces on a headband. They can be corded or wireless. Corded sets, which account for 9 out of 10 sales, have a wire about 8 feet long that connects to your receiver, CD or DVD player, or TV. Wireless sets have a battery-powered headset and an AC-powered transmitter that connects to your audio or video gear.

Price range: $20 to more than $1,000.

Portable. Headphones for use with portable audio devices such as CD and MP3 players vary mostly by whether the earpieces sit on or go into your ears. Because many sacrifice sound quality for size, serious listeners may prefer a home/studio model even with a portable player.

Price range: about $10 to $30.

IMPORTANT FEATURES

Headphones feature a few basic designs. Closed over-the-ear sets cup your ears and create a seal to your head that reduces the amount of sound that escapes. They also muffle ambient sound. But you may miss some things that you want to hear, like a doorbell. Open over-the-ear models don’t press as firmly on the sides of your head and are usually lighter. They let more sound in and out, so late-night listening could keep your spouse awake.

On-ear headphones have earpieces designed to lay flat on your ears, with no gaps. Models can be open or closed. They let more sound in and out than closed over-the-ear headphones. Comfort is a very individual matter; any type of headphone may feel uncomfortable after a while, especially when it’s hot.

Portable models vary in a few ways. Lightweight on-ear headphones, a good choice except in noisy environments, are secured by a headband, neckband, or earclips. The in-ear style features earpieces held securely in place by ear clips or a neckband. These are a good choice except in noisy settings. Earbuds (and a variation called earplugs) are the lightest, but active use may shake earpieces loose. Earplugs are best for noisy settings.

On wireless models, multiple channels are a plus. As with cordless phones, you can switch channels to minimize interference. On some wireless sets, the transmitter uses radio frequency (RF) to communicate with the headphones. Other sets use infrared, much like a TV remote, which requires a line of sight between the headphones and the base.

For connecting headphones, most models have a 1/8-inch plug and a 1/4-inch adapter so they can work with home- and portable-audio systems. Some home/studio models have volume and mute controls. On some models, earpieces swivel and fold for easier storage; of these, some have earpieces that reverse for single-side monitoring, of particular use to DJs.

HOW TO CHOOSE

Performance differences. Headphones should feed you clear, accurate sound with sufficient volume. Based on our tests, corded models are likely to offer better sound quality than wireless units. Wireless models are prone to interference from devices such as cordless phones resulting in static, hissing, or clicking. All the models we’ve tested recently should produce adequate volume with any home-audio device, but some sets exhibit lower sensitivity that results in reduced volume with used with certain portable players.

Recommendations. Price isn’t always the best gauge of sound quality. Some low-priced corded headphones have performed as well as sets costing far more. Headphones scoring good in our Ratings are fine for watching TV or, if you’re not too fussy, for music. Like speakers, headphones may emphasize various parts of the audio spectrum, so sets with the same scores may sound different.

Because potential interference problems with wireless headphones wouldn’t be known until you tried them at home, we suggest you buy wireless models only if they can be returned for a refund.

Whichever type you go for, try them on before buying, if possible, to judge the comfort and sound quality. Online shoppers should be sure to check out return policies.
