Hearing aid signal processing is central to the sound that surrounds the user every day. This article lays out different possible signal-processing strategies, focusing on the choice of filter bank and sampling rate, and how these relate to sound quality. Although both time- and frequency-domain filter banks have their advantages, the sound-quality benefits of a time-domain filter bank outweigh other considerations.
Cochlear Limited (ASX: COH) announced the Food and Drug Administration (FDA)'s clearance of the new Cochlea Baha 6 Max Sound Processor, designed to “improve hearing outcomes for people with SSD (single-sided deafness), conductive or mixed hearing loss.”
Over half (55%) of audiologists do not believe their patients are aware of the link between hearing loss and cognitive decline, according to the results of an audiologist research panel, conducted by the British Irish Hearing Instrument Manufacturers Association (BIHIMA), the Association announced.
Composing music when you have a severe hearing loss can be a real challenge. For example, one has to listen with high acuity to the musical tracks using headphones or in-ear monitors that, by nature, make hearing aid use very difficult or impossible. Here are some insights from an accomplished composer who has devised several solutions for the creation of great music.

How do we assess the speech-in-noise performance of hearing aids in real-life settings to obtain clinically meaningful results? This article looks at several problems related to this issue, including what might constitute “real-life” SNRs and test environments, the variability of patient test scores at different SNRs, and the nonlinearity of modern hearing aids, using the new Widex dual-variable speed compression system as an example.
