Acoustical Systems, Inc. has developed procedures to establish the occupational noise exposure as required by OSHA 1910.95 Occupational Noise Exposure. These workplace noise exposure monitoring procedures measure the exposure level from various types of noise, such as continuous, pure tones, and impulse noise. Reporting is in accordance with OSHA 1910.95 and ANSI Standard S12.19.
Employees are identified for inclusion in the hearing conservation program using the Time-Weighted Average (TWA) sound level assessment. The TWA levels are established for individuals or groups with similar job activities using either the (1) dosimetry method or the (2) Job Function Method.
The implementation of engineering or administrative noise abatement strategies for specific areas will be based on the assessment of typical noise exposure potential over the long term depending on the employees’ typical job assignment. The target areas will be depicted on the Facility Noise Map.
Our monitoring program can be conducted on an annual basis in order to determine if the long term exposure levels or the employee’s noise exposure classification has changed since the last survey. An employee’s noise exposure can change for many reasons including change in job, relocation of operation, addition or deletion of jobs, or employees, repair or modification of equipment, and normal or abnormal wear of equipment and length of work shift.
Through our comprehensive workplace noise exposure monitoring procedures, we can provide a report which can be used by management personnel as well as those involved in various aspects of the plant hearing conservation program, such as medical, safety, industrial hygiene, and engineering personnel. This service will not only assure compliance with OSHA record keeping requirements, but will become a valuable part of an effective hearing conservation program.
