A pure tone average is a calculation that takes the average of your hearing level in each ear. Pure tone average is also relevant when comparing one ear to the other to identify which ear has better hearing. A healthy human ear can hear frequencies ranging from 20 to 20,000 Hz at intensities ranging from 0 to 120 dB.

Fletcher (1929) originally proposed the average of the audiogram at 500–2000 Hz, as the best audiometric prediction of speech hearing. As suggested, the application of the 500, 1000, and 2000 Hz PTA appears to have best application to speech understanding in quiet; however, soon studies began to demonstrate that higher frequency hearing became more …

https://theinfinitekitchen.com/faq/question-why-are-pure-tones-used-to-determine-hearing-sensitivity/
A pure tone audiometry test measures the softest, or least audible, sound that a person can hear. During the test, you will wear earphones and hear a range of sounds directed to one ear at a time. The loudness of sound is measured in decibels (dB). The tone of sound is measured in frequencies (Hz).
Why are pure tones used to determine hearing sensitivity?
https://askinglot.com/why-are-pure-tones-used-to-determine-hearing-sensitivity
Hearing sensitivity within the speech frequencies is known as the pure-tone average (PTA) and can be calculated by adding the thresholds obtained at 500, 1000, and 2000Hz and dividing the result by 3. For audiometric results to be valid, the patient must …

Pure tone audiometry (PTA) air conduction thresholds at frequencies 250, 500, 1000, 2000, 4000 and 8000 Hz were obtained with an Automated Method for Testing Auditory Sensitivity (AMTAS) automated audiometer in a sound-treated booth ( Eikelboom et al., 2013 ). Average four frequency PTA (4FA) was obtained by using the average from the thresholds at 500, 1000, 2000 and 4000 …
Guidelines for Manual Pure-Tone Threshold Audiometry
https://www.asha.org/policy/GL2005-00014/
The American Speech-Hearing-Language Association (ASHA) Guidelines for Manual Pure-Tone Threshold Audiometry contain procedures for accomplishing hearing threshold measurement with pure tones that are applicable in a wide variety of settings. Diagnostic standard pure-tone threshold audiometry, used most often in clinical settings, includes manual air-conduction …

1. Pure tone: A single frequency sound. 2. Audiometer: Equipment used to generate pure tones of varying frequency and loudness and control their presentation. 3. Air conduction (AC) threshold: lowest level dB HL (hearing threshold) at which the subject perceives 50% of pure tones introduced via earphones or speakers.
