Audiogram notches in noise-exposed workers
https://pubmed.ncbi.nlm.nih.gov/17086083/
Objectives: Diagnostic criteria for noise-induced hearing loss include the audiometric notch, yet no standardized definition exists. This study tested whether objective notch metrics could match the clinical judgments of an expert panel. Design: A panel of occupational physicians, otolaryngologists, and audiologists reviewed audiograms of noise-exposed workers.

Noise-Induced Hearing Loss (NIHL) typically demonstrates a “knoch” on the audiogram at 4000k. Sounds around 85 dB for prolonged periods of time can cause hearing loss. If you have to raise your voice to be heard, (normal conversation is around 60dB) you are most likely in an environment with at least 80 dB of noise.

Noise induced hearing loss is where loud noise has caused damage to the hearing organ, the cochlea. This most commonly occurs at 4KHz. Therefore if a hearing loss is noise induced you would expect that the sounds have to be made louder before they are heard at 4KHz than at any other frequency. This leads to a dip in the graph as seen below.

Hz) calculated for the above audiogram is approximately 53 dB HL in each ear, a hearing loss in the moderate range. Degrees of hearing sensitivity include: normal (< 25 dB HL), mild (26 to 40 dB HL), moderate (41 to 55 dB HL), moderately-severe (56 to 70 dB HL), severe (71 to 90 dB HL), and profound (> 90 dB HL).
