## How do you calculate pure tone average?

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 respond to stimulation of the ear being tested.

## What frequencies are used in calculating the pure tone average?

How do you Calculate Pure Tone Average? 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. This value gives a snapshot of an individual’s hearing level in each ear.

What is the high frequency pure tone average?

Usually frequencies of 250–8000 Hz are used in testing because this range represents most of the speech spectrum, although the human ear can detect frequencies from 20–20,000 Hz. Some children can detect even higher frequencies. Pure-tone average (PTA) is the average of hearing sensitivity at 500, 1000, and 2000.

### How do I check my word recognition score?

The word recognition score (WRS) testrequires a list of single syllable words unknown to the patient to be presented at the speech recognition threshold + 30 dBHL. The number of correct words is scored out of the number of presented words to give the WRS.

### What frequency is repeated during pure tone audiometry?

250 to 8000 hertz
The testing procedure is repeated at specific frequencies from 250 to 8000 hertz (Hz, or cycles per second) for each ear, and the thresholds are recorded on a graph called an audiogram.

What is a normal word recognition score?

85-100%
Normal hearing and hearing impaired subjects. The number of correct words is scored out of the number of presented words to give the WRS. A score of 85-100% correct is considered normal when pure tone thresholds are normal (A), but it is common for WRS to decrease with increasing sensorineural hearing loss.
