Which units measure the amplitude of sound waves?
The units that measure the amplitude of sound waves are actually decibels (dB).
To understand how to get the answer, you can start by knowing that amplitude refers to the maximum displacement of a sound wave from its equilibrium position. In the case of sound waves, it relates to the maximum pressure variation caused by the wave.
Decibels (dB) are used to measure the intensity or loudness of sound. The decibel scale is logarithmic and compares the sound intensity to a reference level. In the case of amplitude, the sound pressure level (SPL) is commonly used, which is measured in decibels.
Therefore, the correct answer is "decibels" when it comes to measuring the amplitude of sound waves.
