Description

This study aims to investigate acceptance and performance of the Bluetooth Low Energy Audio-enabled (LE Audio) firmware in the Nucleus 8 Processing Unit, Kanso 3 Nexa Sound Processor, and the Kanso 3 Sound Processor. The investigation includes actual use (take home) of LE Audio firmware releases and the new GN ReSound LE Audio wireless accessories, including the Multi-Mic+, for use in the real-world. Using the final versions of firmware, speech perception performance in noise will be investigated using the Nucleus 8 and Kanso 3 Sound Processors streaming via a Multi-Mic+.
