Technology

ReSound is a provider of sound technology specific to audiology. ReSound uses binaural directional technology to develop products that allow users to manage the amplification of external sounds.

Made for iPhone

In 2013, ReSound partnered with Apple Inc. to develop Made for iPhone hearing aids, allowing users to stream audio directly from their Apple device.[2]

Remote fine-tuning

In 2017, ReSound launched hearing aids with remote fine-tuning capabilities via the cloud.[3]

Direct Android Streaming using Bluetooth-Low-Energy

In 2019, ReSound announced the result of a collaboration with Google and Cochlear Limited to bring direct Android streaming to hearing devices users, using Bluetooth® Low Energy.[4]

iSolate Nanotech

In July 2010, ReSound released iSolate Nanotech technology to add a protective nano-scale polymer coating to hearing aids to protect them from moisture, humidity and perspiration.

iSolate nanotech works by coating all elements of the hearing aid with a thin protective layer that bonds at a molecular level with the internal and external components to ensure no water can be absorbed.[5]

Microphone design

The ReSound microphone design is engineered to use the natural shape of the ear to improve hearing.[6] Microphone design helps maintain natural and directional localisation cues through microphone placement in the concha cymba area of the pinna. Because Behind-the-Ear (BTE) and some traditional custom hearing aids have inefficient microphone placement, distortion can occur if sound collection from the pinna is not utilised. Taking advantage of the pinna effect helps to preserve natural localisation and directional cues.[7]
