Semtech and Sonova want to connect hearing aids in LoRa

[ad_1]

Semtech, the owner of the LoRa technology, also wants to be famous in the medical community. With its partner Sonova, the semiconductor manufacturer is developing an integrated circuit dedicated to the hearing aid.

People with hearing problems are often focused on this problem: the battery of their acoustic device does not hold the charge. In addition, these devices are not very ergonomic. Depending on the situation, adjust the volume that the wheel is usually behind the ear.

Semtech wants to make smart listening devices with IoT

To overcome this defect, manufacturers like Sonova have long explored the possibilities of Bluetooth. The idea is to facilitate user comfort by linking this technology to noise reduction or television viewing features. Only she remains very energy intensive.

The Swiss company Sonova has teamed up with semiconductor manufacturer Semtech. He assisted the hearing aid specialist in designing an integrated circuit capable of supporting 2.4 GHz radio protocols and LoRa frequency bands.

A revolution for a market

Marc Secall, Director Wireless Research & Development at Sonova declares:

"This chip allows Sonova to go in a new direction with her hearing aids. Revolutionary radio technology and energy management are the game changers for our devices. It makes it easier for them to handle a number of applications that were not available from a prosthesis, all with low power consumption and low power supply. Possible use cases range from connectivity to any Bluetooth-enabled audio device (for example, a smartphone or TV) to full-duplex audio transmission between hearing aids and wireless microphones. "

Unfortunately, the two companies do not really detail their partnership. We learn that the integrated circuit requires only 0.8 volts of electrical power. The low power IoT network will probably send data without draining the battery of the device. According to Semtech, connecting hearing aids to the cloud will enable new smart health connected services to be deployed.
