What is the sound pressure amplitude difference associated with a 10 dB increase in air?
sound wave travels with intensity I in a medium. I is directly
proportion to square of sound pressure amplitude. If sound
intensity level
is the ratio of intensity to a reference intensity
I0(which is lowest intensity of sound a person can hear
then
