Sounds are produced when vibrating objects create pressure waves in some medium such as air. When these variations in pressure reach the human eardrum, it
causes the eardrum to vibrate in a similar manner and the ear detects sound. The intensity of sound is measured as power per unit area. The threshold for
hearing (minimum sound detectable by a young, healthy ear) is defined to be I = 10-12 W/m² (watts per square meter). The sound level L, or "loudness" of
sound, is measured in decibels (dB) as L = 10 log
(1). wh
where I is the intensity of the given sound. Round to the nearest integer, if necessary.
