Oconomowoc, WI: Quest Technologies, a 3M company, an employee-owned world leader in the development and manufacture of monitoring instrumentation and software for occupational and environmental health & safety (OEHS) applications announces release of an application note entitled, "Practical Approaches to Hearing Protection Device (HPD) Selection." Overprotection by HPD's is a problem often overlooked in many workplaces and leads to worker resistance to wearing HPD's when required. While single-number methods such as Noise Reduction Ratings (NRR's) are one of the easiest ways to select an HPD, they can result in workers not hearing important communications and warning signals. Quest's application note outlines a method for application-specific HPD selection which overcomes these issues and is significantly simplified by the advent of new technology.
