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.
Sound is a part of our everyday lives, but yet we never stop to think how or why we sound the way we do. Through this unit the children will experiment with how different types of sounds are produced. They will also experiment with how aspects of sound, such as frequency and amplitude effect the way a sound is heard.
