Industrial noise control involves reducing energy dissipated as noise. As a consequence, tool life may be extended, finish on products may be improved and employee's hearing loss may be eliminated. Ostergaard Acoustical Associates' approach to noise control is to first examine the process to determine the source of the noise. Preference is given to noise control techniques that reduce noise production.

Alternatively, to reduce employee exposure, we recommend measures that reduce transmission of sound. Protection of hearing in this manner reduces potential liability for compensation awards and will help comply with federal and local regulations. Ostergaard Acoustical Associates conducts preliminary and comprehensive plant noise surveys to determine employee noise exposure. Noise level measurements are carried out on individual machines. Noise reduction methods are then recommended which are economically feasible and cause a minimum of interference to normal operations. After implementation of the recommendations, additional measurements are made and the results reported
