IHC-TM connect-disconnect in relation to sensitization and masking of a HF-tone burst by a LF tone. IV.
Evidence continues to accumulate that although the outer hair cells (OHCs) of the cochlea are firmly bonded to the tectorial membrane (TM), the inner hair cells (IHCS) are not. This is the fourth in a series of papers that explores how the idea of a set of disconnected hair cells that "impact" the TM is consistent with psychophysical data. The paper extends the exploration to the masking of high-frequency (HF) tone bursts by low-frequency (LF) tones and shows that the model can explain the important features of these complex data.
