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.
Down the side of the audiogram, there is a measure of loudness. quiet sounds, going down to moderate, and then very loud sounds. crosses) marked on the graph represent the quietest sound which can be just heard. measured in a scale called decibels (dB).
