According to the World Health Organization1, around 466 million people worldwide have disabling hearing loss. This number is expected to increase to 900 million people by the year 2050. Google is working with GN Hearing to create a new open specification for hearing aid streaming support on future versions of Android. Users with hearing loss will be able to connect, pair, and monitor their hearing aids so they can hear their phones loudly and clearly.

Hearing aid users expect a high quality, low latency experience with minimal impact on phone and hearing aid battery life. We’ve published a new hearing aid spec for Android smartphones: Audio Streaming for Hearing Aids (ASHA) on Bluetooth Low Energy Connection-Oriented Channels. ASHA is designed to have a minimal impact on battery life with low-latency while maintaining a high quality audio experience for users who rely on hearing aids. We look forward to continually evolving the spec to even better meet the needs of our users.

The spec details the pairing and connectivity, network topology, system architecture, and system requirements for implementing hearing aids using low energy connection-oriented channels. Any hearing aid manufacturer can now build native hearing aid support for Android.

The protocol specification is available here.
