DPOAE Intensity Increase at Individual Dominant Frequency after Short-Term Auditory Exposure
Figure 5
Decay of the DPOAE magnitude increase evoked by 50 dB SPL pure tone in six different subjects. Different tones demonstrate the DPOAE change at the characteristic frequencies. Data points are the measured ΔDPOAE values, and the solid line represents the mathematical model-predicted values. Continuous line shows the curve calculated by the model (see (1)). The dotted line indicates the increasing DPOAE in the presence of efferent neurotransmitters (first part of (1)). Broken line shows the decrease of DPOAE in the presence of the mechanically induced increase in OHC lateral wall stiffness (second part of (1)).
