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.

audiogram reveals pure-tone averages (PTA) of 47dB hearing loss and 45dB HL for the right and left ears, respec-tively. Since each of these PTA values for each ear, we can state with good certainty that the SRT and PTA findings agree with each other, and therefore appear to be reliable. -ing this individual’s ability to repeat

The speech recognition threshold (SRT) is believed to be related primarily to the pure-tone average (PTA) and the steepness of the hearing loss. However, there are indications that it may also be influenced by perceptual or cognitive-linguistic factors, or both, such as meaningfulness of the speech stimuli.

– SRT should be within 7 dB of PTA. Word Recognition (WRs) – Percentage of single words or words in sentences patient hears correctly. – Purpose=Determining how well the person understands speech in each ear. Used diagnostically and for hearing aid purposes. – Lists are presented at suprathreshold

For the PTA and SDT to ‘closely agree’, apply the following rules of thumb: ±6 dB or less = good ±7-12 dB = adequate ±13 dB or more = poor Speech recognition threshold (SRT) The speech recognition threshold (SRT) examines at which level the patient can repeat 50% of the speech material (usually numbers or spondaic words) correctly.

SRT/PTA Agreement 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
