The results of a hearing test, or audiometric test, are recorded on an audiogram. 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.

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.

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.

below. This audiogram shows normal hearing up to 1KHz (mid frequency) and a mild hearing loss in the mid to high frequencies. Depending on the degree of the hearing loss, the sounds may have to be made louder before they were heard than shown below, but the general pattern is likely to be similar for all presbyacusis hearing losses.

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.

How can noise damage our hearing? Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. The bones in the middle ear ...

To establish a cause and effect relationship between noise exposure and hearing loss, the pattern and progression of the audiogram(s) must be consistent with the characteristics of occupational noise induced hearing loss. Additional factors that are considered include: • The client’s age. The pattern and progression of age-related hearing loss (ARHL) is different than that of NIHL.

•hearing loss means partial or total inability to hear marked by a hearing threshold worse than 25 dB at any audiometric test frequency. Hearing loss may be mild (26 to 40 dB), moderate (41 to 70 dB), severe (71 to 90 dB) or profound (equal or more than 91 dB) •abnormal audiogram means an audiogram that shows a hearing loss, hearing
