Combined Active Noise Control and Noise Reduction in Hearing Aids
نویسندگان
چکیده
This paper presents a combined active noise control and noise reduction scheme for hearing aids to tackle secondary path effects and effects of signal leakage through the fitting. While such leakage contributions and the secondary accoustic path from the reciever to the tympanic membrane are usually not taken into account in standard noise reduction systems, they appear to have a non-negligible impact on the final signal quality. Integrating an active noise control system in the existing noise reduction algorithm helps to compensate for these effects. A Filtered-x Multichannel Wiener Filter is presented and compared experimentally with a classic Multichannel Wiener Filter in a noise reduction framework.

Performance and analysis of active noise control system for noise reduction in hearing aids
To reduce the surrounding noise in the hearing aids by using active noise control system. Background noise is particularly damaging the speech intelligibility for people with hearing loss. Background noise reduces the clarity in the speech. So we are able to understand speech in moderately in noise environment even at the sufficient signal to convey the information. There is less redundancy in ...

Background and Aim: Exposure to impact noise (short-term, high intensity) higher than permitted levels results in injury to the auditory system. Armed forces are one of the occupational groups exposed to these types of noises resulting from gunshots. In this study, relevant articles and research on the adverse effects of impact noise, hearing loss, and tinnitus in armed forces and effective con...
متن کاملTheoretical Performance Analysis of ANC-Motivated Noise Reduction Algorithms for Open-Fitting Hearing Aids
Existing noise reduction techniques for open-fitting hearing aids typically disregard the occurrence of signal leakage through the openfitting, leading to a degraded noise reduction performance. Recent miniaturization advances enable to incorporate an internal microphone in the ear mould, which is able to record this signal leakage. Recently, feedforward and combined feedforward-feedback active...
