What is Speech Audiometry?
It is the measurement of the acuity of hearing through generation of tones of known
frequencies and amplitudes.
Speech audiometry has become a fundamental tool in hearing-loss assessment. In conjunction
with pure-tone audiometry, it can aid in determining the degree and type of hearing loss.

Speech Reception Threshold (S.R.T.):

with equal stress) words are correctly identified.
Spondaic words are 2-syllable words spoken with
equal emphasis on each syllable (eg, pancake, hardware,
playground).
