What is low frequency noise?
Low frequency noise is made up of powerful sound waves that travel great distances and cannot be absorbed by passive materials. Engines, fans, motors, and similar devices generate noise that is typically dominated by low frequencies which cannot be stopped by regular earmuffs. ANR, or Active Noise Reduction, is the only proven defense against the effects of low frequency noise.
How do the Noise Cancelling Ear Muffs work?
The Noisebuster Electronic Noise Canceling Safety Earmuffs use a small microphone inside the ear cup to listen to noise going into the ear. Using the integrated electronic system, the earmuffs turn that information into a sound wave, and then create a sound wave directly opposite to that one. The new sound wave is played through a speaker in the ear cup and, when the two waves meet, the low-frequency sound is significantly reduced.
With this technology, you not only have superior protection for your ears, but incredible sound quality from your portable music device without outside interference. You no longer have to turn the volume up to dangerous levels to hear your music, and you will not have to deal with the distortion that comes from music at high volumes. Motor sports fans can use this product in conjunction with a scanner to protect their ears from the sounds of passing cars while still hearing what is going on in the race. The Noisebuster Electronic Noise Canceling Safety Earmuffs are constructed of a tough ABS plastic with a metal headband and include the audio cable and a "AA" battery.
What is Electronic Noise Cancellation (ENC)?
ENC uses a microphone inside the earcup to listen to noise coming into the ear. Using electronics, the system creates a noise wave that is a mirror image of the one coming into the ear. This "anti-noise" wave is played through a speaker, also located in the ear cup and when the offensive noise meets its mirror image, the noise is canceled.
