Abstract : SE SOURCE. Data are presented dealing with physical acoustics, the characteristics of sound and appropriate noise measurements. Hearing loss resulting from both steady-state and impulse noise is discussed along with the factors influencing its acquisition and recovery and the resultant effects upon performance. Subjective and behavioral response to noise is discussed in terms of masking of auditory signals and speech, annoyance and general observation. Current research in the area of nonauditory effects is reviewed varying from cardiovascular alteraltions to the risk of death. Current design criteria are presented for both steady-state and impulse noise for both workspaces and communities. (Author) Portions of this document are not fully legible.
