Explanation Formula used: Write the expression for sound intensity level in dB. β = ( 10 dB ) log 10 ( I I 0 ) (1) Consider the initial level of sound intensity in dB is 0. As the earplugs reduce the sound intensity level by 27 dB, modify equation (1) as follows. β = ( 10 dB ) log 10 ( I I 0 ) − 27 dB Substitute 0 for β , 0 = ( 10 dB ) log 10 ( I I 0 ) − 27

Wave Motion

A wave motion is defined as the propagation of disturbances or transfer of energy and momentum from the state of rest or equilibrium to another point in a medium without any actual transfer of matter between them. In a simple explanation, it is the propa…
