A time-domain digital simulation of hearing aid response.

چکیده
A time-domain digital simulation of an in-the-ear (ITE) hearing aid has been developed. The stimulation allows modeling of nonlinear effects such as compression and amplifier distortion in addition to linear processing and acoustics. The simulation includes a microphone, two-channel compression processing, an amplifier with clipping distortion, a receiver, an ear canal and ear drum, and feedback and direct sound transmission through the vent. Simulation results for a linear hearing aid are similar to those obtained for frequency-domain representations of the analog system. Examples of responses for nonlinear systems are also provided.

متن کاملThe Relationship Between Acceptable Noise Level and Initial Acceptance of Hearing Aid
Introduction: The Acceptable Noise Level (ANL) evaluates the willingness of a listener to hear a continuous speech in the presence of background noise. ANL is related to some variables. Although many studies were accomplished on the relationship between ANL and hearing aid satisfaction, no study was found for the usage of ANL as the predictor of initial hearing aid acquisition. Therefore, the c...
