Noise-induced hearing loss flattens temporal masking valleys and breaks the threshold triad alignment

Evidence

Data produced wit.h similar parameters by a list.ener with noise-induced hearing loss are shown in Fig. 16.28a. The difference is clear because the valleys in the temporal masking patterns are not. as deep as for the normally hearing subjects. … Not only is the threshold in quiet increased by almost 50 dB, but also elevation of the data points corresponding to the “mod”- condition prevent a straight line from being drawn through the three data points. — Professor Dr.-Ing.
