Hearing aid digital signal processing has evolved to include the ability to log, analyze and classify acoustic input, essentially in real-time. The result of this is a series of ongoing acoustic snapshots of what the listener is hearing that can be used in the personalization of the hearing aid (HA) fitting.
This article looks at how each development step differs from traditional fixed directionality, explains how different directional features work, and gives clinical advice for each. In addition, accessories that can further improve SNR via wireless communication are discussed.
Ryan Kalef and his colleagues share with us the results of a Canadian-based clinical trial that was conducted across the country with the aim of providing empirical evidence of the efficacy of the Widex U-platform.
Key considerations when hearing aid engineers design new features are processing time (delay) and battery consumption (current drain). There are not many studies that have investigated delay and current drain in modern digital hearing aids. Therefore, the purpose of this report is to provide benchmark and comparative data on these variables as acquired in the context of a yearly AuD student assignment.
