Different Levels

In multi-speaker environments, cochlear implant (CI) users may attend to a target sound source in a different manner from normal hearing (NH) individuals during a conversation. This study attempted to investigate the effect of conversational sound levels on the mechanisms adopted by CI and NH listeners in selective auditory attention and how it affects their daily conversation. Nine CI users (five bilateral, three unilateral, and one bimodal) and eight NH listeners participated in this study. The behavioral speech recognition scores were collected using a matrix sentences test, and neural tracking to speech envelope was recorded using electroencephalography (EEG). Speech stimuli were presented at three different levels (75, 65, and 55 dB SPL) in the presence of two maskers from three spatially separated speakers. Different combinations of assisted/impaired hearing modes were evaluated for CI users, and the outcomes were analyzed in three categories: electric hearing only, acoustic hearing only, and electric + acoustic hearing. Our results showed that increasing the conversational sound level degraded the selective auditory attention in electrical hearing. On the other hand, increasing the sound level improved the selective auditory attention for the acoustic hearing group. In the NH listeners, however, increasing the sound level did not cause a significant change in the auditory attention. Our result implies that the effect of the sound level on selective auditory attention varies depending on the hearing modes, and the loudness control is necessary for the ease of attending to the conversation by CI users.

Design Innovation

This study aims to innovate and validate the design of a non-electric hearing aid for improved usability. Studies on conventional and existing hearing aids were carried out before the actual study on developing this non-electric hearing aid was done. The final product underwent a series of evaluations in order to verify its viability and usability. Conceptualisation, material selections and concept selections were carried out in order to select the most appropriate concept for this study. The material selection process ensures that the choice of material is appropriate for the specific requirements of the components to be achieved. Subsequently, a detailed cost analysis was carried out to ensure that the manufactured product would be affordable to the customers. Several experiments and tests were performed to evaluate the product’s performance. Although a validated prototype for a non-electric hearing aid is in hand, future improvements on the fabricated product are still needed in order to ready the product for its future commercialisation phase.
