NHCA/CAOHC Webinar Series: Hearing Protection Devices Update
The third NHCA/CAOHC Webinar series: Hearing Protection Devices Update, was successfully presented on July 27, 2023. With ongoing changes and innovations, it can be difficult for OHCs, Course Directors, and Professional Supervisors to stay on top of current products. The objective of this webinar was to provide NHCA members and the many hearing conservationists certified through CAOHC with an opportunity to learn about new or unusual products and ask questions.

Tim Chismar, the North American Product Marketer for the 3M™ PELTOR Portfolio, led the webinar with a review of Peltor’s wide range of communication-enabled electronic hearing protection, including both muffs and in-ear solutions. These included Bluetooth-enabled headsets, in-ear speech microphone, on-demand fit testing, environmental listening, and group communication capabilities.

Dr. Susan Cooper from CavCom followed with an introduction to CavCom’s Talk Through Your Ears and TeamTalk technology. This in-ear hearing protection is compatible with respirators and other PPE, comes in either custom or universal-style earpieces, and allows for conversational, hands-free communication.

Next up was James Schrack with Decibullz. This company’s thermoplastic, i.e., heat moldable,  plug makes a customizable product more accessible and affordable. Plugs can be molded in the workplace or at home, and remolded if needed. Options include different high fidelity filters, percussive filters for shooting, and radio adaptors for use as an earpiece.

Wrapping up, Andy Wetjen from Protective Industrial Products (PIP), provided  an overview of PIP’s comprehensive range of passive hearing protection: earplugs (foam and preformed), banded plugs, and muffs. PIP also offers customization, with selection of cup color and even logo printing on muffs.

The webinar was well-attended, with a record 124 participants. The recorded webinar will be available on the NHCA Learning Management System. Based on attendance and audience interaction, it seems like a topic worth revisiting!

Thank you to our presenters for sharing your time and expertise to make this webinar possible!

Fact Sheet on Expanded OSHA Reporting Requirements

The Occupational Safety and Health Administration (OSHA) issued a Final Rule amending its occupational injury and illness recordkeeping regulation. It will become effective on January 1, 2024. Establishments with 100 or more employees in designated industries will be required to electronically submit their OSHA Forms 300 and 301 information once a year.

OSHA released a new fact sheet to help employers understand the expanded requirements for electronically submitting injury and illness information.

More information is available on OSHA’s Injury and Illness Recordkeeping and Reporting Requirements website and in the OSHA press release and Federal Register Notice.

Safe-in-Sound Excellence in Hearing Loss Prevention Awards - Self-Nominations Accepted through August 18!

Nominations for the annual Safe-in-Sound Excellence in Hearing Loss Prevention Awards are now being accepted. The awards are co-sponsored by NIOSH, the National Hearing Conservation Association (NHCA), and the Council for Accreditation in Occupational Hearing Conservation (CAOHC).
Two awards are presented: one for excellence and one for innovation. According to Safe-in-Sound Review Committee Coordinator, Scott Schneider, CIH, judges for the excellence award consider what nominees have done to limit or eliminate the risks from noise exposures in their workplace. Previous winners have been recognized for purchasing quieter tools or equipment, regularly checking noise levels, providing effective hearing protection tailored to workers’ needs, conducting careful analysis of the annual hearing test results, training all workers effectively on noise both on and off the job, controlling noise to the levels recommended by NIOSH, and evaluating their program each year to make improvements.
Self-nominations will be accepted through August 18, 2023. Winners are invited to receive the award and present their real-world success stories at our annual NHCA Conference, February 8-10, 2024, in Albuquerque, NM.  For information on how to submit a nomination, please visit the Safe-in-Sound website at:
