In 2007, the CIN started with 25 principal investigators as cluster applicants, as stipulated in the DFG call for bids. When the CIN cluster was approved further scientists from a range of institutions were incorporated, to make up the 48 'founding members' of the CIN. Since the beginning of 2014 the CIN has consisted of over 80 scientists in total. The membership process involves an application to the steering committee in which the candidate outlines his or her scientific profile and submits a list of publications. The committee's decision is based purely on the scientific excellence of each candidate.

Field of Research
Our mission is to understand the basis of sound processing by the healthy and pathological cochlea, as well as to develop new tools for differential diagnosis. Research into sound processing, in collaboration with Dr. Harasztosi, aims at understanding: 1) mechanoelectrical transduction in hair-cell stereocilia, 2) electromechanical transduction in outer hair cells, 3) cochlear amplification, and 4) calcium-related homeostatic mechanisms. Development of diagnostic tools, in collaboration with Dr. Dalhoff, entails elucidating mechanisms of: 1) the generation of otoacoustic emissions, and 2) retrograde transmission through the middle ear, as well as developing: 1) optimum stimulus strategies, and 2) laserinterferometric recording techniques for non-invasive assessment of cochlear emissions in patients.
