Research summary
This study is looking at a method called ‘ABR’, which measures the electrical activity in your brain (brain waves) when you hear sounds. This study will look at the electrical activity in your brain when you hear high-pitched sounds. First, we will find the quietest sounds you can hear. Then we will use ‘ABR’ to measure the quietest sounds that trigger electrical activity in your brain. This is to find out if there is a difference between the quietest sounds you 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.
Lay summary of study results: A total of 30 ears with different levels of hearing were tested. There was an average difference of 34.8 between PTA and ABR thresholds.
Therefore, a correction of 35 may be used to estimate behavioural hearing levels from ABR thresholds at the frequency we looked at (6kHz).
