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.

Represents conduction from the bones of the skull to the inner ear (bypassing the TM and ossicles) Measured between 250 to 4000 Hz 5. Pure-Tone Average (PTA): average thresholds for the speech frequencies (500, 1000, 2000 Hz) Typically should be within 10 dB of the speech reception threshold 6.

A Pure Tone Average (PTA) refers to the average of hearing threshold levels at a set of specified frequencies: typically 500, 1000, 2000 and 4000 Hz. If your PTA is <25 dB, your overall hearing would be considered to be within normal limits. Click to see full answer. Furthermore, what are normal hearing test results?
Comparison of Pure-Tone Average Methods for …

However, few studies have used the pure-tone average (PTA), including high-frequency ranges, for the estimation of hearing loss caused by lead and cadmium exposure. We estimated hearing loss using the PTA test, in low-frequency, speech frequency, and high-frequency ranges and compared the differences in the results using 3 PTA calculation methods.
Pure Tone Audiometry - Need Hearing Aid?

The average of your audiogram is determined by calculating an average of the Air conduction thresholds obtained at 500Hz, 1000Hz and 2000Hz. Following are the hearing loss degrees: * If this average falles between 0dB to 25dB then your hearing is normal * If this average falls in between 25dB to 40dB then you have a mild hearing loss

An evaluation of both systems has been published recently by the author. 8,9 In both WHO hearing-impairment grading systems, the severity is quantified by the pure-tone average at 500, 1000, 2000, and 4000 Hz in the better ear. Although the boundaries are derived just for frequencies of 500 through 4000 Hz, the horizontal lines are extended across the entire range …

While hearing in the real world is much more complex than detecting the presence of brief pure-tone stimuli, hearing difficulty is highly related to pure-tone audiometry. How we define normal in regard to pure-tone hearing is deeply entwined in our differential diagnosis and treatment recommendations and, therefore, has significant implications ...
What is SRT on an audiogram?
https://askinglot.com/what-is-srt-on-an-audiogram
Pure-tone average (PTA) is the average of hearing sensitivity at 500, 1000, and 2000. This average should approximate the speech reception threshold (SRT), within 5 dB, and the speech detection threshold (SDT), within 6–8 dB.
