NHCA Workshop To Address Field Verification Of HPD Attenuation
Health & Safety
Smithfield, RI — A persistent problem in hearing protection–that of assessing the actual performance of hearing protection devices in the field–will be addressed by a panel of leading experts at this year’s conference of the National Hearing Conservation Association. Moderated by Brad Witt, MA, CCC-A, Audiology and Regulatory Affairs Manager for the Bacou-Dalloz Hearing Safety Group, the workshop will present four different systems for measuring real-world attenuation and provide a hands-on demonstration of each to allow attendees to evaluate their effectiveness. A panel discussion will follow.
“Until recently, there has been no consistent method of actually measuring in the field how much protection is provided by a Hearing Protection Device (HPD)” said Witt. “And the apparent disparity between published ratings (NRRs) and real-world performance has caused OSHA and NIOSH to recommend various de-rating schemes–reducing published ratings by up to 70% in some cases–to ensure adequate protection. However, critics have argued that de-rating not only exaggerates the problem, but risks overprotection by forcing workers to use protectors with higher ratings than they really need.”
New developments in field verification of HPD attenuation help bridge the gap between laboratory and workplace, and can help eliminate concerns of both under- and over-protection. The NHCA workshop will review four systems in detail, presented by these leading experts:
Dr. Kevin Michael of Michael and Associates will demonstrate his FitCheck verification system and doseBusters measured exposure.
Dr. Sig Soli of the House Ear Institute will present a QuickFit attenuation verification system.
Lee Hager of Sonomax will present the Sonomax system for verified custom protection.
Following the demonstrations, a panel discussion/Q&A session will address several related issues, including: the possible obsolescence of laboratory-based NRRs; whether field verification will eliminate the need for de-rating; whether it will fulfill all aspects of OSHA compliance; whether field verification can be used in court; as well as future trends for field verification.
The 2006 NHCA Conference is the Association’s 31st annual conference and will be held on February 16-18 in Tampa, FL. More information can be found on the NHCA website at www.hearingconservation.org or by emailing Karen Wojdyla at firstname.lastname@example.org
