directivity factor (Q)

Science; Acoustics

By definition a noise source that radiates uniformly in all directions, spherically has a Q = 1. Place the same source on the ground so the energy can only radiate ...

displacement (s)

Science; Acoustics

Change in position of an object in meters - vector quantity. v = u + at where v = velocity, u = start velocity, a = acceleration in m/s 2 and t = time. In the field of acoustics, ...

Science; Acoustics

Constant percentage (or relative) bandwidth resolution. This is often preferred for acoustic measurements because it best simulates the way in which the human ear perceives sound.
