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.

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/
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.

However, long or repeated exposure to sounds at or above 85 dBA can cause hearing loss. The louder the sound, the shorter the amount of time it takes for NIHL to happen. Here are the average decibel ratings of some familiar sounds: Normal conversation 60-70 dBA Movie theater 74-104 dBA Motorcyles and dirt bikes 80-110 dBA

Therefore, in early noise- induced hearing loss, the average hearing thresholds at 500, 1000, and 2000 Hz are better than the average at 3000, 4000, and 6000, and the hearing level at 8000 Hz is usually better than the ...

Noise induced hearing loss “NIHL” • 1 of 2 most common causes of acquired SNHL (the other is presbycusis) – Caused by impulsive or long term noise exposure – Permissible noise levels=85 dB SPL/8 hours • Most preventable cause of acquired hearing loss • Landmark “noise notch”

A clinician’s guide to noise-induced hearing loss Noise-induced hearing loss (NIHL) is a hearing loss that typically occurs gradually over time due to prolonged exposure to excessive noise levels greater than 85 decibels (dBA). It may also occur from exposure to a very intense sound, such as an explosive blast or gun fire. This is referred to as an
