Lesson: Sound Wave Power and Intensity
In this lesson, we will learn how to relate sound intensity level in decibels to sound wave intensity, amplitude, and pressure changes that waves produce.

An exposure to a sound intensity level of 170 dB for s may cause hearing damage. What energy in joules is transmitted to an eardrum of diameter 0.600 cm exposed to such a dose of sound?
The amplitude of a sound wave is measured in terms of its maximum gauge pressure. By what factor does the amplitude of a sound wave increase if the sound intensity level goes up by 25.0 dB?
The threshold of human hearing is approximately −8.00 dB. What is the intensity of a sound at this level?
