What is it about?
Binaural hearing, hearing with both ears, is extremely important in order to understand speech in a noisy environment, for example in a busy restaurant. Many people with hearing impairments, for example hearing aid users, struggle a lot in such scenarios. In this study, we evaluated a novel technique using specialized speech signals, which allow us to record brain signals to assess the brain's binaural hearing ability in a noisy environment.

Why is it important?
The evaluated method allows us to objectively record the brain's response, which corresponds to the person's binaural hearing ability. While other methods can record similar brain signals, they use artificial acoustic stimuli, like clicks, pure tones, or noise. Because our method uses normal speech, it can not only be utilized in more realistic scenarios, but could also be combined with established behavioral clinical tests.
Perspectives
This study is a continuation of previous research by the authors related to binaural hearing. We hope to further develop and refine the proposed method, and to eventually test it alongside established tests.
