Development and Comparison of Objective and Psychoacoustic Methods to Quantify Efferent Auditory Feedback

Context: 
The medial olivocochlear (MOC) system is a critical neural feedback loop that allows the brain to dynamically control the sensitivity of the auditory periphery, in particular on outer hair cells (OHCs). This system is believed to have a pivotal role for hearing in noisy environments. Numerous studies suggest its effectiveness varies greatly between individuals and that it declines particularly with age.
