Engineering Controls for Occupational Noise …
SOUND & VIBRATION/JANUARY 2012 Despite significant advances in hearing protection technology, Hearing Conservation Programs are not an adequate substitute for Engineering and administrative Controls . Studies of small and medium companies have found clinically significant hearing losses in all age brackets. Several have found widespread and serious gaps in compliance with requirements such as audiomet-ric testing, training, record keeping, and exposure measurement. These failures are particularly prevalent among small companies. Although opponents of requirements for Engineering Controls maintain that they are particularly difficult for small companies to implement, the per-worker costs of hearing conservation re-quirements for small companies are much greater than for large companies, and the use of Engineering and administrative Controls is likely to be more cost-effective than hearing protection devices (HPDs) for small businesses.
