Low-frequency seismoacoustic ambient noise levels

The Journal of the Acoustical Society of America, 1988
Studies of the infrasonic ocean noise induced by the interaction of surface waves have shown that the noise levels are dependent not only on the ocean-wave field but also on the geoacoustic properties of the environment. A full understanding of the processes involved requires an examination of the role of the inhomogeneous components of the induced ...

Ambient Noise Levels in Industrial Audiometric Test Rooms

AIHAJ, 1994
In 1983 the Occupational Safety and Health Administration (OSHA) specified maximum permissible ambient noise levels (MPANLs) that would allow valid hearing threshold measurements in an audiometric test room. However, ambient noise sound pressure levels (SPLs) in rooms used for industrial hearing tests are unknown. The present study reports octave band (
