Experience
A Silent
Revolution!

• Minimize noise fatigue by
  reducing low
  frequency sound
  (below 400 Hz)
  throughout the cabin...while
  reducing the vibrational 
  pounding your
  body takes.

• Reduce noise 
  and facilitate  conversation for everyone in the aircraft without requiring an intercom.

• Now you may experience electronic noise reduction throughout the general aviation fleet from Quiet Flight, LLC and its nationwide Installation Centers.

• No headset required.

Fly Without Noise Vibrations
Beating Your Head & Body

Quiet Flight, LLC, under exclusive license from Cooper Tire & Rubber Company is proud to present this electronic aircraft noise control system for the general aviation fleet.

Aircraft travel remains noisy, and at times, a stressful form of travel.  Despite the best efforts of modern sound absorbing materials and headsets... the long sound wave from low frequency (propeller, engine and exhaust) noises is not attenuated to the degree electronic attenuation can obtain.  

Thus, the application of electronic noise control is ideally suited for the aircraft cabin.

You know the limitation... sound absorbing materials block out only a fraction of the noise in an airplane cabin.  Aviation headsets are typically uncomfortable, heavy, frequently cause headaches and pinched ears.

With electronic noise control technology, 
all passengers in the cabin benefit from  the noise attenuation simultaneously.
Fatigue for everyone on board is reduced, conversation throughout the cabin is enhanced, all ears receive protection and none of these benefits require an uncomfortable headset.

As headsets only protect at the opening of the ear, there is no fatigue inducing vibration control over your body and full head areas by employing only a headset.  The Quiet Flight method achieves these vibrational reductions at both the ear opening and at the body.

Electronic noise cancellation specifically reduces low frequency noise below 400 Hz (Hz stands for hertz, which refers to the number of frequency vibrations per second). Low frequency noise is considered a perpetrator of noise fatigue because these large, long waves literally pound against your body.  Propeller blade noise and engine vibration all fall in this range, although high frequency wind noise does not

If you're not familiar with active noise cancellation, it's relatively simple technology to explain - although until now it's been incredibly costly to implement.  Active noise cancellation analyzes the individual air pressure waves which make up a noise, identifying the distinct high pressure "peaks" and low pressure "troughs" of each component.

Coopers ENVisys system utilizes a highly engineered control system to block the noise waves by creating and broadcasting "anti-noise" waves, which are essentially mirror image sound waves.   The result is not unlike the effect of adding a positive number to its negative counterpart; in essence, the peaks and valleys of the original waves are countered by those of the anti-noise waves, significantly reducing the noise.

We're confident you'll be impressed with what you see (and hear) with this technology. The Quiet flight system is field-installable on virtually any aircraft from single-engine, piston-powered craft to turbo prop airplanes.
