Intensity Of Sound Wave

Sound Waves

The intensity of a sound wave gets reduced by 20% on passing through a slab. The reduction intensity on passage through two such consecutive slabs

In the previous example, if the density of air r = 1 . 22 kg //m^(3) , then find the intensity of a sound wave of the largest amplitude tolerable to the human ear.

Intensity of sound depends upon

Intensity Of The Waves

Properties of Electromagnetic Waves | Intensity of EM Waves

Assertion : Sound level increases linearly with intensity of sound. Reason : If intensity of sound is doubled, sound level increases approximatel 3 dB .
