Study Summary

This trial is testing how well people can understand speech when different aspects of the sound are changed.

Who is the study for?

This trial is for individuals with mild or moderate symmetric sensorineural hearing loss, as well as those with normal hearing. It's not suitable for people with asymmetric hearing thresholds greater than 15 decibels difference between ears up to 4 kHz, or severe hearing loss exceeding 60 dB at any frequency up to 4 kHz.Check my eligibility

What is being tested?

The study is testing signal processing techniques designed to make speech sounds clearer by manipulating the rapid changes in frequency and amplitude that characterize spoken language. The goal is to improve intelligibility of speech for listeners.See study design

What are the potential side effects?

Since this trial involves non-invasive signal processing methods rather than medication or surgery, traditional side effects are not applicable. Participants may experience fatigue from listening tasks or discomfort from wearing headphones.
