The efferent-effect filter at 4 kHz has a Q10 of about 3.1

Evidence

The 10 dB bandwidth of the efferent-effect filter at 4000 Hz was about 1300 Hz (Q10 of 3.1). The FDMC method can be used to provide an unbiased measure of the bandwidth of the efferent effect filter using ipsilateral efferent stimulation. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5951
