Noise monitoring instrumentation makes data collection simple. But inconsistent analysis and interpretation of exposure sample data can lead to problems preventing hearing loss. It’s easy to fall into a false sense of security that your hearing conservation program (HCP) is based on correct assumptions. You should review your decision process to justify including each individual worker in the program based on a full and complete understanding of the data you are collecting.
Noise exposure data has become relatively simple to obtain, even in extreme environments, using miniature, bodily-worn (usually shoulder-mounted) personal dosimeters. They are easy to use and calibrate, and can be operated with minimal experience or training. Dosimeters have gone from providing a very basic set of dose calculations to producing literally dozens of calculated noise exposure metrics to meet various sampling methods and regulatory standards in use around the world.
