Abstract
With time window FFT analysis the latency of cochlear acoustic emissions was calculated. If mainly one frequency is present in the emission signal, this latency is frequency dependent: the lower the frequency, the longer the latency. In the second part of this paper the measurement of minimum stimulus energy to evoke a cochlear acoustic emission is described. This energy is so low (1 eV) that processes at molecular level are likely to play an important role.
