The sound intensity is simply the product of velocity and pressure. Velocity is measure in "meters per second" and pressure in Pascal or Newton per square meter.

WebThe decibel scale is used to measure the loudness of a sound (dB). An increase in volume that is ten times as loud as before is represented by a difference of ten decibels. Hence, a sound that is 70 decibels is ten times as intense as a sound that is 60 decibels, and a sound that is 50 decibels is one hundred times as intense. WebUsed to measure acoustical and electrical power Describes a large range of values in smaller values that are easier to work with Not an absolute scale, it is a relative scale, that compares one sound to another (ratio of two sounds).
