On the cost of introducing speech-like properties to a stimulus for auditory steady-state response measurements
Abstract
For the purpose of objectively validating hearing-aid fittings in pre-lingual infants, auditory steady-state response (ASSR) measurements are investigated. This paper examines the cost of introducing speech-like features into the ASSR stimulus, which is done to ensure that the hearing aid processes the stimulus as if it were real speech. The main findings were a reduction in ASSR amplitude of 4 dB and an increase in detection time by a factor of 1.6, while detection rates were unaffected given sufficient recording time.
