چکیده

Our purpose is to apply a basilar hardware membrane model (BMM) to hearing-aid systems to solve some of the problem in existing hearing-aid systems. In this study, we construct a BMM using Simulink. Also, we experiment on the response characteristics of our BMM implementation to C6713DSK, using real sounds and hearing-loss sounds, which imitate a hearing-impaired person’s hearing ability. It is shown that our BMM can emphasize characteristic frequencies, and hearingloss sounds are improved so that it may become easier for a hearing-impaired person to hear. These results suggest that our BMM using Simulink is effective in hearing-aid systems.

A novel method of analysing and compa algorithms using auditory time-fre

A new and potentially important method for predicting, analysing and comparing responses of hearing aid algorithms is studied and presented here. This method is based on a timefrequency representation (TFR) generated by a computational auditory model. Hearing impairment is simulated by a change of parameters of the auditory model. To simulate the basilar membrane (BM) filtering part of the audi...

Case Report of Unusual complications after hearing aid fitting that required surgical management

The making of ear mould for hearing aids is generally considered to be a safe process. However, there are a few reported cases of complications caused during mould making. We report the case of a man with 69 years age, where the process of making the mould for a hearing aid led to the perforation of the tympanic membrane and pouring of mould material into the middle ear, necessitating surgical ...

A study of hearing aid gain functions based on a nonlinear nonlocal feedforward cochlea model.

A model based sound amplification method is proposed and studied to enhance the ability of the hearing impaired. The model consists of mechanical equations on basilar membrane and outer hair cell (OHC). The OHC is described by a nonlinear nonlocal feedforward model. In addition, a perceptive correction is defined to account for the lumped effect of higher level auditory processing, motivated by...

Anatomical predictions of hearing in the North Atlantic right whale.

Some knowledge of the hearing abilities of right whales is important for understanding their acoustic communication system and possible impacts of anthropogenic noise. Traditional behavioral or physiological techniques to test hearing are not feasible with right whales. Previous research on the hearing of marine mammals has shown that functional models are reliable estimators of hearing sensiti...

A Sound Processor for Cochlear Implant Using a Simple Dual Path Nonlinear Model of Basilar Membrane

We propose a new active nonlinear model of the frequency response of the basilar membrane in biological cochlea called the simple dual path nonlinear (SDPN) model and a novel sound processing strategy for cochlear implants (CIs) based upon this model. The SDPN model was developed to utilize the advantages of the level-dependent frequency response characteristics of the basilar membrane for robu...
