Latency Measures of the Acoustic Reflex: Normal Versus Sensorineural

Abstract

An ordered series of latency measures of the acoustic reflex was obtained on 23 normal-hearing and 23 sensorineural hearing-impaired subjects. Five parameters from each reflex recording were defined and measured. Statistical analysis revealed no difference between the two groups for the contraction or initial portion of the response. However, following the cessation of the stimulus, the sensorineural group demonstrated a significantly longer relaxation time

Key Words:

• Latency of the acoustic reflex
• Stepedial muscle reflex
• Impedance measurement
