Lucy Chu Research the active noise decrease (ANR) technology enforce in noise-cancelling headph unitys. How does it work? What physics principles be involved? What are some other applications that use ANR technology? Choose iodin application, and explain how it works. (List your resources) (Due Monday 19 March) Active Noise step-down is a technology that reduces the unwonted noise outside the headphones to provide the user a high quality audio service. It is also eff as the noise cancellation and active noise control. The ANR technology creates an anti-noise make out that results in detrimental kerfuffle and cancels out the original noise. By creating a wave of the same amplitude and frequency as the external noise, two waves backsheeshs and troughs are arranged such that the meridian of one wave lines up with the trough of the other wave, thereby cancels out one another. One of the applications of the active noise reduction technology is the muffler in in ternal combustion engines.

It is a device designed to reduce the loud functions created by the engine. on that point are tubes in the muffler designed to formulate sound waves produced by the engine. The sound waves enter the tube and the chambers. The fiberglass withdrawal and the resonating chambers that are tuned to cause destructive interference absorb the noise. Therefore, the original noise is cancelled out. graphic symbol: hypertext transfer protocol://electronics.howstuffworks.com/gadgets/audio-music/noise-canceling-headphone3.htm http://www.silentium.com/about/active-noise-control/ http://www.2carpros.com/articles/how-exhaust-systems-workIf you want to get a full essay, order it on our website: OrderEssay.net
