Acoustics_Vocabulary


 * __Acoustic Vocabulary:__**

Ambient noise encompasses all sound present in a given environment, being usually a composite of sounds from many sources near and far. ** Architectural Acoustics ** The control of noise in a building space to adequately support the communications function within the space and its effect on the occupants. The qualities of the building materials used to determine its character with respect to distinct hearing. In acoustics, the cycle is the complete oscillation of pressure above and below the atmospheric static pressure. Deflection is the distance an elastic body or spring moves when subjected to a static or dynamic force. Typical units are inches or mm. ** Diffusion ** The scattering or random reflection of a sound wave from a surface. The directions of reflected sound is changed so that listeners may have sensation of sound coming from all directions at equal levels. ** Echo ** Reflected sound producing a distinct repetition of the original sound. Echo in mountains is distinct by reason of travel after original signal has ceased. ** Elastomeric ** Flexible, low modulus material capable of expanding and contracting and returning to original dimensions without fatigue.
