2. Vibrations in the air creates waves of pressure that are perceived as sound. Sound waves vary in sound pressure level (amplitude) and in frequency or pitch. ‘Acoustics’ is the branch of physics that studies sound. Sound pressure levels (loudness or volume) are measured in decibels (dB). Humans hear sound over a very broad range
3. Sound is energy, caused by vibrations of the molecules. Too much volume can permanently damage your ears and hearing. The perception of loudness depend on the frequency or pitch. Harmonics cause the same note played on a cello to sound different from one played on a piano.
