Signal Processing and Sound Quality

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.

A 10-Year Review of the Earlens System, Part 3: What’s the Big Deal about Audibility and Broader Audible Bandwidth?

This 3-part series is a high-level review of the data that has accumulated across more than 10 years of clinical research with the technology at the heart of the Earlens system. In Part 1, we dove into the speech understanding data to demonstrate how increasing the audible bandwidth of processed sound results in improved speech understanding performance from several perspectives. In Part 2, we discussed the perceptual benefits to naturalness and overall sound quality. Finally, in Part 3, we’ll deep dive into the restoration of audibility and how the Earlens approach to overall audibility improvement is reliably achieved in fittings via direct drive—as well as who may benefit from this.
