and wonder just what threshold means and how threshold is measured. Clinically, audiologists define audiometric threshold (in a pure tone air conduction hearing test) as the level at which a test subject responds to a test signal (tone) 50% of the time on ascending trials.In simpler terms, threshold is the hearing level at which the test stimulus

https://pubmed.ncbi.nlm.nih.gov/26650376/
Hearing thresholds were measured in sound field and under a supraaural earphone for FRESH noise, warbled tones, and narrowband noise. Pure-tone thresholds were also measured under the supraaural earphone. Results: FRESH noise thresholds were similar to pure-tone and warbled-tone thresholds regardless of audiometric configuration. For the group with gradually sloping …

The list below outlines different hearing loss thresholds as they are determined in relation to an individual with a normal hearing threshold. Mild hearing loss: 25 to 40 dB higher than normal. Moderate hearing loss: 40 to 55 dB higher than normal. Moderate-to-severe hearing loss: 55 to 70 dB higher than normal.

Test frequencies in audiometry are derived from the musical scale, and are generally octave intervals. An octave is a tone with a frequency that is exactly twice that of a reference tone. Therefore, the basic audiometric test frequencies are 500, 1000, 2000, 4000, and 8000 Hz.

Technique. Pure tone audiometric air conduction testing is performed by presenting a pure tone to the ear through an earphone and measuring the lowest intensity in decibels (dB) at which this tone is perceived 50% of the time. This measurement is called threshold. The testing procedure is repeated at specific frequencies from 250 to 8000 hertz (Hz, or cycles per second) for each …

An increase of 10 dB means a 10-fold increase in sound intensity. An increase of 20 dB means the sound is 100-fold more intense. Standard audiograms test between 0 and 110dB. For reference, normal conversation is around 60 dB. Common sounds and their intensity (dB) Near-total silence. 0 dB. Lawnmower. 90 dB.

Pure-tone audiometry. Pure-tone audiometry is a “gold” standard test of audiologic examination. Its role is to assess whether hearing acuity is normal or impaired. Air conduction hearing thresholds are measured for tonal stimuli at the range of frequencies from 0.125 kHz to 8 kHz with the use of headphones.
