Short 10 Min Presentation on Speech Audiogram & Audiometry. Delivered by Abubakkar Raheel (4th Year Mbbs) Frontier Medical College, Abbottabad, Pakistan.

1. 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.

2. 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).

3. Speech Audiometry
Speech Discrimination Score (S.D.S.):
Percentage of phonetically balanced (single
syllable) words correctly identified at 40 dB
above S.R.T.

4. 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
