This study involves imaging ears with hearing loss with a new system that allows the user to see the middle ear bones and measure their movement in response to sound.
This study is an exploratory clinical investigation to obtain pilot imaging and vibrometry data in patients with various hearing loss aetiologies and to identify qualitative and quantitative features associated with specific pathologies. The data collected in this study is intended to support future investigations into the accuracy of the system in diagnosing specific middle ear disorders.
