Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
After surgery subjects sometimes state that the quality of sound is suboptimal, even though their hearing ability has improved significantly. Some subjects subjectively hear distorted sounds, which often disappear several weeks after surgery.
This study aims at capturing for the first time at which frequencies and sound intensities these distortions are perceived. Additionally, the portion of patients perceiving these sound distortions and the length of time over which the distortions occur are assessed.
