Finding the owners manual for my Pioneer CRWM62R is greatly appreciated. I had searched several other web sites with no success. Although my manual was not listed on your site for immediate download, I recevied an email within a few hours that my ower's manual was posted for me. I had no difficulty downloading the manual for my 20 year old multi-cassette player. Owner Manuals provides a service that is valuable, easy-to-use, accurate , efficient, and priced fairly. I thank you.

The problem of noise The negative effects of noise pollution have been proven by studies, and everybody will have experienced them: Nervousness Lack of concentration Irritability And these are only the most obvious effects on the human body. Noise also affects the autonomic nervous system and can lead to permanent hearing damage. There are a multitude of noise sources, and the individual very often has no influence over them. The only solution when being in a noisy place is protecting oneself against ambient noise. These noise problems are particularly prevalent in an aircraft cockpit where a pilot often has to have the communications headset so loud as to risk permanent hearing damage. With the NoiseGard® system, Sennheiser has come up with an effective solution. These operating instructions explain the NoiseGard® principle and show you how to use the NoiseGard® headset.

The unit of sound levels is the decibel (dB). A noise reduction of 10 dB is generally perceived as halving of the loudness, another 10 dB decrease corresponds to a loudness reduction of 75 %, and so on.
