What type of graph shows the results of pure tone hearing audiometry tests?
The audiogram is a graph showing the results of a pure-tone hearing test. It will show how loud sounds need to be at different frequencies for you to hear them. The audiogram shows the type, degree, and configuration of hearing loss.
What is pure tone average?
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.
What does pure tone average mean?
How do you read a 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 is pure tone test?
Pure Tone Audiometry is a behavioural test that is aimed at measuring the severity and balance of an individual hearing loss.
What is a pure tone hearing screening?
Pure tone audiometry. Pure tone audiometry ( PTA) is the key hearing test used to identify hearing threshold levels of an individual, enabling determination of the degree, type and configuration of a hearing loss and thus providing a basis for diagnosis and management. PTA is a subjective, behavioural measurement of a hearing threshold,…
What is pure tone threshold?
Pure-tone threshold audiometry is the measurement of an individual’s hearing sensitivity for calibrated pure tones. Three general methods are used: (a) manual audiometry , also referred to as conventional audiometry; (b) automatic audiometry, also known as Békésy audiometry; and (c) computerized audiometry.
What is a pure tone hearing screen?
Pure tone audiometry (PTA) is the key hearing test used to identify hearing threshold levels of an individual, enabling determination of the degree, type and configuration of a hearing loss and thus providing a basis for diagnosis and management.
