2024 NHCA/CAOHC Webinar on April 17th Register today!

When: April 17, 2024, 5:00pm - 6:00pm Eastern Time
CEUs: 1-hour CEU (AAA) and (0.1 ASHA)
Pricing: $38- NHCA/CAOHC members, others $50

About the Webinar: In this webinar, two experienced occupational audiologists will describe a standard threshold shift of hearing, as defined by OSHA and the general concept of work-relatedness per OSHA’s record-keeping rules (29 CFR 1904.5). The NHCA Guidelines for Recording Hearing Loss on the OSHA 300 Log (National Hearing Conservation Association, 2011), which provides a guideline for assessing work-relatedness, will be reviewed.  In a question/answer format, frequently asked questions and sample cases will be discussed. An open dialogue on participants’ questions on hearing threshold level shifts and work-relatedness will follow.

Presenters: Marjorie Grantham, Carol Snyderwine

Learning Objectives: 
  1. Define a standard threshold shift (STS) as defined by OSHA.
  2. Describe work-relatedness per OSHA’s record-keeping rules (29 CFR 1904.5).
  3. Describe OSHA’s basis for determining recordability on the OSHA Form 300.
  4. Identify factors which should and should not be considered in determining work-relatedness.
  5. Apply this knowledge in assessing potentially recordable losses.

Cancellation Policy: Webinar purchases are non-refundable.

'Hearing is Quality of Life, Part 2' Video Is Now Available!
The second motivational video in the series is available here on the NHCA website! The National Occupational Research Agenda (NORA) Hearing Loss Prevention Cross-Sector Council produced this series of videos featuring conversations with noise-exposed workers who have experienced hearing loss and/or tinnitus. These are short motivational videos intended for a lay worker audience to increase awareness and protective behavior. NHCA is exclusively hosting the series. The third video is in development and more participants are needed! If you know anyone (family, friend, colleague) with hearing issues who might be interested in participating, please contact Elizabeth Masterson at [email protected]. It is a very short time commitment and could greatly contribute to our field! Thank you!

The sound of a healthy coral reef may help heal damaged reefs
We know that healing sounds can be therapeutic to people, animals, and plants.  But how about coral reefs?  A new study shows that playing the sounds associated with a healthy reef in the vicinity of a damaged reef may actually help heal the damage.
