Be it hearing threshold or intent, our technology shows promising potential in accurately measuring both, offering a valuable use case for enhancing auditory assessments and personalised hearing solutions

Hearing Threshold

The Auditory Steady State Response (ASSR) – Unlocking the Secrets of Hearing Abilities

Discover how our brainwaves react to sounds with a regular rhythm or frequency. The Auditory Steady State Response (ASSR) provides valuable insights into your hearing abilities. By analyzing the ASSR, audiologists and healthcare professionals can effectively determine your unique hearing threshold by frequency. Using this technology, it is possible to pinpoint the specific frequency range and intensity levels of sounds that you are capable of perceiving.

Hearing Intent

In-Ear EEG Sensors – Empowering Conversations in Noisy Environments

Compared to traditional eye tracking devices, our innovative in-ear EEG sensors offer a less intrusive and more advanced solution. These sensors not only measure brain activity but also record electrooculography (EOG) signals from the ear canal. This breakthrough technology enables us to detect eye movement and gaze, a feature that proves invaluable for hearing aid devices.

Imagine having directional microphones that automatically focus on the sounds you want to hear. With our in-ear EEG sensors, we can steer these microphones towards the sounds you are actively attending to. This means you can engage in conversations effortlessly, even in noisy environments.


The IDUN Guardian has been proven to reliably measure the brain activity of the auditory cortex. It has been validated to estimate hearing threshold through ASSR, detect hearing intent, and interpret auditory attention. As the first commercially available in-ear EEG system with these capabilities, the IDUN Guardian has the potential to significantly enhance and improve modern hearing aids.
