Just How Noise Reducing Headphones Operate

Have you been on a plane with your headphones, and found yourself not able to enjoy that movie you were watching because there was a lot of noise coming from the engine, your snoring seatmate, or other noise producing factors around you that you could still hear? Have you ever found yourself wishing you could enjoy that train ride better, if perhaps you could enjoy your personal in-ear entertainment but rather disappointed because you got that unwanted train mechanism striking the rail tracks? Don't you wish there was a way to block out those unwanted sounds from the surrounding and isolate what you would like to listen from your headphones in its purest timbre?

These were exactly the wishes which Lawrence J. Fogel and Dr. Amar Bose had in mind once they began developing earphones that may isolate unwanted ambient noise. They both individually attempted to study and develop ways to produce something which would answer their dissatisfaction to noise caused the airplane's engine while riding an airplane. Following a decade of researching and development, the very first noise cancelling headphones were released by Bose.

Noise-cancelling headphones were created to minimize those unwanted noises around one's environment.They help isolate the produced sound by producing reverse polar sound waves like those which are coming from the external surroundings. This really is made possible by Active Noise Control or simply known as ANC.

ANC basically works though a microphone, placed near the ear, which serves as the sensor. When this picks up those external sounds, its electric circuitry produces sound waves which are reverse in polarity. Acting as anti-noise sound waves, the sound picked up externally is cancelled and minimized to the listener wearing the noise-canceling headphones. The result is pure sound quality at whatever volume is selected.

Currently out there, you should typically find Noise Canceling headphones which have ANC for mostly low frequency noise. It is because lower frequency sound waves sound multi-directional instead of sounding from a singular source, making it easier for the ear to pick up. They'd also contain longer wave lengths which will make it tougher to block.

For sounds that have higher frequencies and are shorter in wave lengths, companies would usually count on their other noise minimization techniques, for example ear cups design and materials, to block them. Because they have shorter wave lengths, they'd be easier to block and block out.

With the thought of frequency and wave sound length having an inverse relationship, companies have opted to create noise-canceling headphones with an ANC for lower frequencies only because it would entail having a more simple electronic circuitry. Other techniques anyway could be sufficient to make the noise-blocking effect that one would wish in a noise-canceling headphone.

Noise-canceling headphones are already gaining their popularity around the world. Not only do they have entertainment benefits, but ear-drum maintenance also. Because a user would not need to raise the volume to hear only what she or he is hearing, less stress is placed to the ear drum. Speak about a double benefit!

Sennheiser Headphones RS130 Wireless

Sennheiser Headphones are quickly becoming the DE FACTO standard when it comes to watching movies on your home theater high end audio system but this article speaks definitely about the Sennheiser Earphones RS 130.

At just 9.8 ounces, the RS130s from Sennheiser are so comfortable on your head that you'll forget you even have them on as soon as your audio comes streaming through. I'm of the opinion that this is preferable because if you decide to get up -- assuming you're sitting down -- and walk around while you listen, you won't be getting any long springy headphone cord tangled up in anything. Super crisp sound and no uncomfortable squeezing on your ears like so many other brands of headphones. The RS130s are easy to recharge or simply install some new AAA batteries. Intelligent auto-tuning makes these earphones even more popular among high end audio system owners.

The ear pads are made of delicate foam and are blanketed in fabric. The headband experiences a corresponding handling with three such pads, between which are two all-metal strips that answer as the charging contacts when you rest the headphones on the base station. Rechargeable batteries are included with the headphones and I was very fortunate to see that only two AAA size are necessary. This sure enough facilitates with the weight of the headphones which should have a absolute impact on comfort during long-term listening sessions.

For this test and review, several of us viewed an old movie -- THE GREAT ESCAPE. I just happened to have purchased it and thought it would be a satisfactory motion picture to test with the RS 130s and boy was I correct! In fact, viewing THE GREAT ESCAPE with these Sennheiser headphones caused me to remember my Dad taking me to the movies when I was just a little kid. The Great Escape was the first movie I ever attended in a movie theater and the memories of that motion picture run deep. Now I've seen this same movie many many times on television since I've grown up but never once did any of those times bring back the memory of watching my very first movie with my Dad.

Crazy I know but I totally attribute that to the sound of these wireless headphones. To put it quite simply, the sound is nothing short of ASTOUNDING. And since I know this movie by heart and actually own the video we were watching, I even got up to go to the rest room and make some snacks for everyone with the RS130 earphones still on my head and in so doing, I could literally watch the movie in my mind's eye. I've never gone through anything like this before.

About the only insignificant problem I acknowledged was when I was running along a wall. This was the only time I discovered just a bit of static but it was never sufficient to take me out of the movie even though I was no longer sitting in front of the movie.

The RS130 sports Sennheiser's own SRS Headphone virtual-surround-sound system which is compatible with two-channel audio sources. As I stated before, the RS 130s' reception remained uniform throughout our home theatre cinema experience. Most of the 'tolerable' wireless headphone sets I've researched are priced over $500 and any anything less expensive is almost always unusable. Thankfully, the Sennheiser RS130s are a solid compromise between price and quality. They won't break the bank and enable you to genuinely enjoy your listening experience. Add their topnotch overall design and you have a very viable choice for replacing your wired headphones.
