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.
Is the frequency of sound measured in units called decibels?  The frequency of sound is measured in Hertz named after   Heinrich Rudolf Hertz, the first person to measure  electromagnetic waves. A single Hertz represents a single â¦cycle per  second. Humans can hear sound from about 40 hertz to nearly 15000  Hertz (also called 15 kilohertz, abbreviated as 15 Khz). Some  people with exceptional hearing range may go up to 20 Khz. Some  animals can hear even higher frequencies.     Decibels are a measurement of how loud a sound is.
