Pure Tone Audiometry - an overview | ScienceDirect Topics
https://www.sciencedirect.com/topics/medicine-and-dentistry/pure-tone-audiometry
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. 11. For audiometric results to be valid, the patient must respond to stimulation of the ear being tested.

Pure tone audiometry indicates what hear-ing thresholds (dB) are required to just be able to perceive a tone at different frequencies (Hz). A pure tone audiology threshold at a specific frequency is the decibel level at which a sound is perceived 50% of the time. The decibel scale used in pure tone audiometry is dB Hearing Level (dB HL). The dB HL intensity scale is
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 …
Understanding and Interpreting Pure Tone Audiometry
http://www.indiaspeechandhearing.com/blog/hearing-tests/
Pure Tone Audiometry. PTA or pure tone audiometry is a hearing test accepted worldwide as a standard protocol for determining hearing levels or hearing loss. Prerequisites for this test: -> The individual undergoing this test should be 8 years and above. -> PTA should be done in an acoustically treated room with least noise interference.

Visual reinforcement audiometry (VRA) (6mo to 2yo): child turns to visual cue in response to sound stimulus; Conditioned play audiometry (CPA)(2yo to 5yo): child interacts with toy or object in response to sound stimulus. Can assess laterality. Conventional pure-tone audiometry (5yo+): raising hand in response to sound stimulus.

diseases, tympanometry (a test of middle ear function), pure tone air conduction thresholds, pure tone bone conduction thresholds, and/or speech discrimination testing. Sometimes these evaluations were done on all NHANES examinees, and some surveys included hearing evaluations on only a subset of examinees (such as children or adults).

The SRT should agree with the pure tone average (PTA) ±5 dB Exception: In steeply sloped high frequency losses, the SRT will be better than the PTA In this case, add the thresholds at 500 Hz and 1000 Hz, then divide by 2 If the SRT and PTA are not in agreement you should re-instruct the member on all testing
