Details About Pitch. Although for most practical purposes, the pitch of a sound can be said to be simply a measure of its frequency, there are circumstances in which a constant frequency sound can be perceived to be changing in pitch.
What Can Be Measured By The Decibel Scale. The decibel scale can be used to measure audio in a variety of different ways. The decibel can be used to measure sound pressure level, sound intensity level, voltage level and power, just to name a few. This provides a valuable reference tool for the audio engineer, technical engineer, and the audio equipment designer.
