Classification of audiograms in the prevention of noise-induced hearing loss: A clinical perspective The UKHSE audiogram classification scheme has the advantage of providing a straightforward, easy to determine classification that allows …
Audiogram notches in noise-exposed workers
https://pubmed.ncbi.nlm.nih.gov/17086083/
Design: A panel of occupational physicians, otolaryngologists, and audiologists reviewed audiograms of noise-exposed workers. In a two-sample process, the panel judged whether a notch was present and whether hearing loss had progressed in a notch pattern. Quantitative notch metrics were compared against expert decisions.

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.

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.

A noise induced hearing loss audiogram has an unusual shape. It has what is known as a spike. This spike shows a big fall in hearing levels for certain sounds, which is a strong sign that hearing has been damaged from continuous excessive noise exposure. Can an industrial deafness hearing test be faked?

An audiogram is used to chart the results according to loudness (dB) and pitch (Hz).On an audiogram, noise induced hearing loss (NIHL) will usually be seen first as a slight loss of hearing in the 4 kHz region. This dip in hearing is more commonly known as a ‘notch’ in the audiogram.
Predicting Tinnitus Pitch From Patients' Audiograms …

from the audiograms of tinnitus patients with noise-induced hearing loss and tone-like tinnitus. Our key assumption is that the mean firing rates of central auditory neurons are controlled by homeostatic plas-ticity. Decreased auditory nerve activity after hearing loss is counter-acted through an increase of the neuronal response gain, which

The prevalence of notched audiograms varied greatly by definition (31.7%, 25.9%, 47.2%, and 11.7% for methods 1, 2, 3, and 4, respectively). In this cohort, a history of noise exposure was common (56.2% for occupational noise, 71.7% for noisy hobbies, 13.4% for firearms, 81.2% for any of these three sources).

OBJECTIVES To investigate the relation between different types of exposure to noise and a classic sign of noise induced hearing loss (NIHL), the audiometric notch. METHODS The study sample had exposure to both continuous and impulse noise and was drawn from a population of electrical transmission workers. Audiograms, taken as part of a hearing …
