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.
What Can Be Measured By The Decibel Scale. The decibel scale can be used to measure audio in a variety of different ways. The decibel can be used to measure sound pressure level, sound intensity level, voltage level and power, just to name a few. This provides a valuable reference tool for the audio engineer, technical engineer, and the audio equipment designer.
