Video Summary

Dr. Risson, a Clinical Associate Professor at Ohio University, discussed noise-induced hearing loss (NIHL) and hearing conservation. NIHL, a major socially isolating condition, affects social interaction and productivity, costing an estimated $105 billion annually. It is the second most common occupational illness after dermatologic issues, yet 100% preventable. Dr. Risson highlighted that hearing loss odds triple every decade of life, notably affecting high frequencies most, impairing speech comprehension.<br /><br />Occupational hearing conservation programs become mandatory when noise exposure reaches a time-weighted average of 85 dB over an 8-hour period. These programs include noise monitoring, providing protective devices, and educating employees about noise dangers. Audiograms conducted within six months of exposure establish a baseline, and annual tests track potential standard threshold shifts (STS), defined as a 10 dB change in hearing threshold averages at 2,000, 3,000, and 4,000 Hz frequencies.<br /><br />Education on proper hearing protection usage is vital, as noise-exposed workers face significantly higher tinnitus risks. Multiple hearing protection options should be made freely available, and worn consistently. Addressing NIHL early with adequate protection not only prevents irreversible damage but also substantial financial liabilities.
