What are some of the terms regarding sound measurement?
Absorption -The product of absorption coefficient and surface area of a material, in units of sabins, used to designate the amount of sound absorbed by that material. -The properties of a material composition to convert sound energy into heat thereby reducing the amount of energy that can be reflected. Acoustical Analysis -A review of a space to determine the level or reverberation or reflected sound in the space (in seconds) as influenced by the building materials used in the construction of the space. -Also, a study of the amount of acoustical absorption required to reduce reverberation and noise. Anechoic Chamber -A room having terminations (walls, floor, and ceiling) that absorb all sound incident on them. -Used in laboratories to measure direct sound fields from sources. A-Weighted Sound Level -A measure of sound pressure level designed to model the response of the human ear, which does not respond equally to all frequencies. The ear is less efficient at low and high frequencies t
