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 Audiometry

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

Minimum intensity at which 50% of spondee (disyllable

with equal stress) words are correctly identified.

Spondaic words are 2-syllable words spoken with

equal emphasis on each syllable (eg, pancake, hardware,

playground).

Speech Audiometry

Speech Discrimination Score (S.D.S.):

Percentage of phonetically balanced (single

syllable) words correctly identified at 40 dB

above S.R.T.

Speech Audiometry

Indications• Differ b/w cochlear & retro-cochlear lesions.• Assessment of degree and type of hearing loss• Examination of word recognition abilities• Examination of discomfort or tolerance to

speech stimuli
