Sound Isolation & Noise Cancelation Technology

Isolation Headphones were invented by a studio session drummer for drummers, home studios, stage and studio musicians, and anyone who wants serious isolation
They use specially designed earmuffs that passively attenuate surrounding sound by 28 decibels (that’s more than those $300 pairs!) and custom fitted, high quality speaker assembly. They are designed to protect your eardrums from damage and improve your recording and performing.

Sound isolating earphones were originally developed as Personal Monitor Systems to allow musicians to hear their own performances in loud onstage environments. Sound isolating earphones work by using soft, pliable sleeves to block background noise, allowing small, high-performance drivers to deliver incredibly precise sound directly to the ear. These professional-quality earphones are now available for use with all of your portable digital devices. The seal created by a sound isolating earphone physically blocks most frequencies of background noise. Active noise cancellation "headphones" are generally larger, heavier and battery-driven. The active cancellation process negates selected frequencies through a complex process that can even introduce unwanted artifacts into the resulting audio. The natural sound isolation properties of a properly fitted in ear earphone exceeds the performance of even the most expensive active noise cancellation alternatives. Sound isolation makes it possible to hear greater detail at a lower volume than is possible with earbuds or most headphones intended for portable use. Lower-volume listening means less fatigue over extended periods and is safer than trying to overcome background noise by turning up the volume. This makes sound isolating earphones the ideal choice for commuting, travel, exercise, study, or work – any activity where you desire portable, hi-fidelity sound.

Sound Engineers use them to monitor the mixer board during live performances while isolating their ears from main speakers.

Stage and Studio Drummers
use them when they want to hear how drums are being mixed without having head-phones at high volume.

These headphones allow Studio Musicians to hear only the studio mix during recording – eliminating costly return trips to the control room.

You can use them at Stadium and Dome Events to listen to "LIVE" broadcasts at medium volume and block out most stadium noise while watching the game.

They also use them in NASCAR" by using an inexpensive stereo to mono plug, the scanner can plug into his or her scanner and have the best isolation available to monitor the pit crews and driver.

Sound isolating headphones work like an earplug to block background noise naturally. This enables you to listen comfortably at lower volumes-even in loud environments. And unlike bulky headphones utilizing active noise cancellation technology, no artifacts are introduced into your listening experience. Sound isolating earphones are also much smaller and don’t require batteries.

This past year I’ve gone through like 5 packs of earbuds.

I found a good pair in terms of sound/isolation ($20 HVC) but they were very flimsy and seeing as I’m a college student (who ends up bundling the buds in my pockets a lot) I can’t afford to replace them every month or so….

So now I’m willing to pay a bit more for two things:

1) Durability: I have a cheap pair of JVC bubbles that have taken a LOT of abuse and still work- unfortunately the sound is crap .

2) Sound isolation for others. I don’t want to have to wonder if other people near me in the library can hear it when Abba comes on the shuffle.

3) A good sound- clear and enjoyeable- no need for more.

Thanks!

I refuse to join the trend of those that like to drop $30+ on earbuds. one of the stupidest ways to spend your money

I also just bundle my earbuds into a pile and shove them in my pocket and they’ve been fine for 9 months

I use those white earbuds that Apple sends with iPods. they’re $30 by themselves and they have new in ear ones with better quality. they cost $30 more than your limit but sound good from what I hear

Hey, currently I have Beats by Dr. Dre In-Ear Headphones. I was kind of disappointed in the bass. I need your opinion on the BEST IN EAR EARPHONES! I was thinking about Shure, but their ear buds are too big? And maybe the Monster Turbines? Thanks

shure earphones rock, if you can afford the price tag. i love dr dre, but unfortunately he is a rapper, not an earphone manufacturer. monster just used him for product placement or in other words to make their average product popular. if you want bass knocking earphones that still give clear sound and you cannot afford shure then i would recommend the next best thing in my opinion, gadgetronx in ear earphones. many styles, colors, and flavors to decide from.
so far i have 3 pair – yummy. and love each pair. each pair knocks with rumbling vibrating bass while still providing nice clear sound. dude, you can hear everything in the music. like back up singers – no one cared to know was there. like instruments and stuff too.
very good spend if you are looking for good quality earphones. so next time dont believe the hype and do what i did with the dr dre earphones, store test them first and not at best buy either – those fools will tell you anything is cool, just to get you to buy it. most claim they have it, but come on – seriously – do you think a best buy worker can afford dr dre beats earphones. what a joke. any ways, thats my answer – hope it helps.

A couple of friends of mine wish to isolate the sound between the combined living and dining room and the bedrooms of their house. The combined living and dining area joins directly to the main corridor of the house and this main corridor runs the full length of the house to the front door. Access to the three bedrooms is through individual doors that open directly onto this main corridor. Obviously the best way would be two sets of doors with sufficient air between them at the end of the corridor nearest the combined living and dining area but THIS IS NOT AN OPTION, on aesthetic grounds. What else can be done?

The doors won’t mean anything if the walls are paper thin. Which can be soundproofed by the material is not cheap, and you’d have to rip the wall open.

There’s cheaper way like using acoustic tile, but if doors are unacceptable for "aesthetic reasons", then I can’t imagine those being much more attractive.

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"

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

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

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.

I heard noise cancelling needs batteries, major turn off? And which one do you recommend, is there any good brand that’s cheap?

sound isolating completely covers the ears and blocks sound.

noise cancelling have an audio amp built in and a microphone so that when you are wearing the headphones, you can hear normally until you are in a loud noise enviorment and the headphones become isolating headphones.

Hunters and shooters use noise cancelling. The report from a shot causes the headphones to block the loud report.

I buy my shooting headphones at Harbor Freight, they are under $25.00 with a coupon and are every bit as good as the $99.00 ones from Dick’s Sporting Goods.

my neighbors slam the door a lot, and my roommate stays up really late when i’m trying to sleep. she opens/closes her drawers a lot, shuffles papers loudly, etc. will sound-isolating earphones work in this situation?

Some are better than others.

Noise cancelling earphones work in two ways:

(1) they block out a good amount of the ambient noise by covering you ear or blocking your ear canal.
(2) they create a negative image of the noise and play it through the earpiece, rather effectively reducing the remaining noise that gets past the intentional blocking.

Noise cancelling earphones work best, of course, when there is other "noise" (or music) to help over-ride the noise you want to cancel. Just using the earphones by themselves, and not connected to an MP3 or other sound-generating device, may not be as effective as you might wish. There will always be some quantity of sound that gets to your eardrums directly through your head. This is, in part, known as "bone conduction hearing", and there is no way to prevent it.

I use a set of noise cancelling headphones to practice on my Casio keyboard while my wife watches TV. With the noise cancelling turned off, the headphones block out a lot of the TV sound. With the headphones switched on, there is a noticeable reduction in the sound I hear from the TV; but I do still hear a little of it. When I start playing the keyboard, I don’t hear the TV at all because the keyboard is louder than what little sound from the TV still gets through.

To see beyond what astronomers can see using traditional telescopes, which count on visible light for their viewing, a radio telescope is designed to hear the sounds from outer space as opposed to the sights. Most designed as a parabolic antenna, a radio telescope allows the user to listen to sounds emanating from sources in space.

Most people with an interest in space have probably heard of the Search for ExtraTerrestrial Activity (SETA), which is a group of people monitoring space for signals with a radio telescope that may indicate life from outer space. To date there has been no success in isolating sounds from space that can be blamed on extraterrestrial sources, except of course in movies.

Neutral hydrogen and carbon monoxide are examples of radio waves picked up with a radio telescope, along with other sources of electromagnetic signals picked up as sound. The first radio telescope in use was back in 1937, a dish about 30-feet in diameter, with interest growing ever since and the first arrays being put in use in the 1950s. Today, the largest is the 1894-foot diameter RATAN600 in Russia.

Sound From Space Sparks Science Fiction Imagination

With the ability to receive sound signals from space picked up on a radio telescope, the imagination of writers and amateur star gazers have fueled by beliefs that some of the sounds are being created by other life in space. Continual argument persists on the existence of life in space and signals not readily identified is used as questionable indications of extraterrestrial life.

A very large array of radio telescope dishes in New Mexico boasts 27 dish antenna, each with a diameter of about 82 feet. They work in tandem searching the skies for sounds, acknowledging that considering the speed of sound is much slower than the speed of light, any sound picked up could be from yesterday or hundred of years ago.

Under construction in Western Europe is a low frequency array radio telescope, which will consist of 25,000 smaller antenna designed to develop radio pictures of the sky based on the origins and current location of the sources of sounds picked up by the array. Clusters of antenna will be spread out over an area approximately 220 miles square. With the added power to pull in radio signals from space it is hoped a better map of this galaxy and adjacent galaxies can provide a better understanding of the space being lived in.
