This study is looking at a method called 'ABR', which measures the electrical activity in the brain (brain waves) when we hear sounds. This study will look at the electrical activity in participants brains in response to high-pitched sounds. First, the investigators will find the quietest sounds the participants can hear. Then the investigators will use 'ABR' to measure the quietest sounds that trigger electrical activity in participants brains'. This is to find out if there is a difference between the quietest sounds participants can hear, and the quietest sounds that trigger these brain waves. We are also interested in finding out if having a hearing loss affects this.

Difference between ABR and PTA thresholds
Compare ABR thresholds to PTA thresholds at 6 and 8 kHz in normal hearing adults and adults with sensorineural hearing loss.
through study completion, 4-5 months
Effect of participants hearing level on ABR-PTA threshold differences
through study completion, 4-5 months
Participants with hearing levels of 20dBHL or better at 6 and 8kHz frequencies of sound
Participants with hearing levels of 25-40dBHL at 6 and 8kHz frequencies of sound
Participants with hearing levels of 45-70dBHL at 6 and 8kHz frequencies of sound
Participants with hearing levels of 75- 90dBHL at 6 and 8kHz frequencies of sound
There is no intervention this is an observational study to develop a diagnostic test
Registry-reported names are shown in full. Names without a link have not yet been matched to a Syfrah profile.
This study needs a range of participants with different hearing levels.
