An audiogram shows the softest sounds (volume: soft to loud) you hear at each frequency (low to high pitches). The lower the line on the graph, the worse your hearing is at that frequency.
Audiogram showing a typical "noise notch" in the left ear (normal hearing in the right ear) "Conventional" pure tone audiometry (testing frequencies up to 8 kHz) is the basic measure of hearing status. [6]

Audiogram, obtained using mobile application, can be used to adjust hearing aid application. [2] An alternative approach to assessing hearing impairment is through the utilization of a speech-in-noise test. This evaluation method assesses an individual's ability to comprehend speech amidst background noise.
There is a transition between these two areas described. Factor A is a problem only in low noise levels, whereas Factor D is a problem when the noise level is high. Hearing impairment (based on the audiogram) and auditory handicap (based on speech discrimination in noise) data was reviewed by Reinier Plomp [who?]. This led to the formulation of ...
The shape of an audiogram shows the relative configuration of the hearing loss, such as a Carhart notch for otosclerosis, 'noise' notch for noise-induced damage, high frequency rolloff for presbycusis, or a flat audiogram for conductive hearing loss.

On an audiogram, the resulting configuration has a distinctive notch, called a 'noise' notch. As ageing and other effects contribute to higher frequency loss (6–8 kHz on an audiogram), this notch may be obscured and entirely disappear. Various governmental, industry, and standards organizations set noise standards. [10]
