- Pure tone Audiometry-PTA
Description:
Functional Hearing, or peripheral hearing if you prefer, is usually tested for each ear separately, under clinically calibrated headphones. Audiologist near me in IndiraNagar. Different frequencies (represented in Hertz or Hz) are tested at different intensity levels (represented in decibels or dB). The healthy human ear can typically detect between 20 and 20 000 Hz with an intensity range of 0 to 120 dB. With our current daily life activities, hearing in humans is mainly used for speech understanding.

Speech sound components can be represented from 125-8000 Hz depending on the speaker. Therefore, pure tone audiometry testing usually concentrates on the frequencies represented in male and female human voices, namely 250 – 8000 Hz. The number of select frequencies tested can vary upon the age of the person tested, the reason for the test, and the time allotted for testing.
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. As speech sounds are more densely represented in the mid frequencies, the outlying frequencies are not included in the PTA calculation to allow for more consistent comparisons. Audiology Clinics in RR Nagar. If your PTA is <25 dB, your overall hearing would be considered to be within normal limits. With a PTA of 95 dB, your hearing would be considered in the profound range. PTA is also helpful when comparing one ear to the other, to determine if you have a ‘better hearing’ side.

Pure tone Audiometry-PTA
Pure-tone audiometry is a behavioral test used to measure hearing sensitivity. This measure involves the peripheral and central auditory systems.
Tympanometry- Tymp
tympanometry is a medical test that measures the function and movement of the eardrum and middle ear. The results of tympanometry are represented on a graph called a tympanogram.
BERA
Hearing loss in children is difficult to know from the beginning. Hearing loss can cause speech, language, cognitive, social and emotional problems. Therefore, it will be better if the hearing test in children is done early.
OAE
The OAE (Otoacoustic Emissions) test checks part of the inner ear’s response to sound. The test is mostly done on infants and children who may not be able to respond to behavioral hearing tests because of their age.
Speech
The test is usually completed in five to ten minutes and has two components – one measures your speech reception threshold (SRT) and the other determines your speech discrimination (SD) abilities.
Hearing Aid Trail- HAT
A person with hearing loss which cannot be surgically or medically corrected is rehabilitated with amplification devices. Hearing aids do not restore hearing ability but they boost up the signal.
Special test
An audiometry evaluation is a painless, noninvasive hearing test that measures a person's ability to hear different sounds, pitches, or frequencies.
