• Description:
  As part of a long-term goal to reduce noise induced hearing loss in the construction industry, the National Institute for Occupational Safety and Health (NIOSH) estimated the A-weighted sound pressure level at the operator's ear (LPA,est) from the A-weighted sound power (LWA) measurements of 118 various model powered hand tools using the diffuse-field point source model Eyring theory. LPA,est from the model are compared to sound pressure measurements (LPA, meas) acquired from a microphone located in the nominal hearing zone of a simulated powered hand tool operator. This paper provides a basis for the direct substitution of LWA for LPA,meas and a comparison of LPA,est to LPA, meas. The magnitude of LWA is found to be a reasonable predictor of the magnitude of sound pressure level exposure, or LPA, meas, that a powered hand tool operator might experience across a variety of acoustical environments. As such, LWA magnitude can be used directly to select appropriate hearing protection and estimate worker' noise exposure. [Description provided by NIOSH]
