my panasonic home theatre (dvd player) does the same , it has nothing to do with the anynet, if u connect using hdmi, (well mine is hdmi as well) it just tries to be smart and shuts down when u shut down the tv. i dunno if u can stop this from happening,
The energy in a sound wave can be measured using Decibels. The Decibel Meter shows examples of things that make noise and measurements in decibels. Amplitude measures how forceful the wave is. It is measured in decibels or dBA of sound pressure. 0 dBA is the softest level that a person can hear.
This is a background page to the multimedia chapters Sound and Quantifying Sound. 1  Definition and examples. 2  Sound files to show the size of a decibel. 3  Standard reference levels (absolute sound level)  Logarithmic 1  measures. The filters used for dB(A) and dB( C) Loudness, phons and sones, hearing response curves.
