Synthetic signals for verifying noise reduction systems in digital hearing instruments

Abstract

Hearing instrument development involves the acoustic verification of system functionality. The used test signals should allow efficient repetition of tests. Synthetic stimuli are therefore proposed as test signals, because they can be tailored to the test objectives. For the purpose of frequency response measurements in digital hearing instruments, we present a synthesis procedure targeted at test signals for modulation-based noise reduction systems. The resulting stimuli are assessed during measurement of the noise reduction performance in an exemplary hearing instrument.
