Acoustic Terms and Definitions: Impact Noise or Impact Sound

Impact Noise or impact sound is a form of structure-borne sound that occurs when an object impacts on another, resulting in the generation and transmission of sound.

Physically speaking, impact sound represents a short lasting impulsive force, created by dropping object of mass (m) over the floor with high transmission velocity (v); with little attenuation, generating enough energy to excite the building structure and cause it to vibrate.
