This project investigates sensorineural hearing loss, which primarily involves a decrease in auditory sensitivity where sounds become less audible or even inaudible. While hearing aids can amplify sounds to compensate for this loss of sensitivity, they may not fully restore normal hearing perception, particularly in noisy environments. This is because sensorineural hearing loss can also involve other deficits beyond just reduced sensitivity, known as suprathreshold deficits, which cannot be detected through standard hearing tests.
In this project we explore the prevalence and mechanisms of suprathreshold deficits, with the long-term goal of making hearing aids more effective.
