Excessive noise exposure is regulated by the Occupational Safety and Health Administration (OSHA) regulations for general industry and construction. Noise above the action limit of 85 decibels and the permissible exposure limit of 90 decibels (slow response) is considered excessive and requires an employer to protect the employees working in areas that exceed these limits. Hearing conservation programs or engineering controls may be implemented to control the hazard. Contact us for noise monitoring and program generation as well as the institution of engineering controls.

Noise Surveys

Detailed noise surveys are conducted with computerized instruments, noise logging dosimeters to confirm noise exposures for representative employee positions. Dosimeter data is compared to standards to evaluate hearing conservation program needs. Software is used to creates unique reports that present each sample in a highly readable and visual format.

Personal Noise Dosimetry

Our industrial hygienist technicians use noise dosimetry to measure personnel exposure to noise levels through the work day. Noise levels surrounding the individual are measured and recorded over an eight-hour period (or for the full work shift). The technician also observes and records general information about personnel work processes.

Area Noise Level Monitoring

Our industrial hygienist technicians measure and record noise levels in a general work area to determine the extent of noise exposure or to measure the effectiveness of engineering controls applied to a machine (such as dampeners, insulation, isolation, distance). The noise level meter is placed in a fixed location in the work area or near the source of the noise.
