Commonly referred to as the mean-square sound-pressure ratio, sound energy,
or just plain energy, acoustic energy is the squared sound pressure (often
frequency weighted), divided by the squared reference sound pressure of 20
FPa, the threshold of human hearing. It is arithmetically equivalent to
10LEV÷10,
where LEV is the sound level, expressed in decibels. |
