Design win; Bluetooth Smart in a hearing aid receives stereo audio direct from iOS devices

August 08, 2014 // By Graham Prophet
Using Bluetooth Smart wireless silicon from Nordic Semiconductor, the ReSound LiNX from Danish hearing aid giant, GN ReSound, allows users to customise and fine-tune it through a dedicated app for any iOS device which can also be used to pin-point the location of a misplaced hearing aid device and can recognise and optimise settings in frequently visited places.

GN ReSound specified Nordic's nRF51822 Systems-on-Chip (SoCs) to provide the Bluetooth Smart (formerly known as Bluetooth low energy) wireless connectivity in the what GN ReSound claims is the world's most advanced and compact hearing aid that can address 90% of all hearing losses.

Technically described as a fully-integrated wireless 'Receiver-in-the-Ear', the ReSound LiNX hearing aid can receive high quality stereo audio direct from iOS devices such as an iPhone, iPad, or iPod touch, without the need for any other intermediary (typically pendant-like) remote or accessory, which according to GN ReSound is a common drawback of traditional hearing aid designs.
