Spontaneous otoacoustic emissions cluster near SFOAE fine-structure maxima but remain undetectable there.

Evidence

SOAEs usually occur near maxima of SFOAEs fine structure (Bergevin et al. 2012 ; Dewey and Dhar 2014 ), but SOAEs are not always detectable at such maxima. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5763

The relative decision weights were compared with the level differences between tones at the maxima and tones at the minima of the fine structure for two listeners (Fig. 3 ). These listeners have detectable SOAEs, which occur near SFOAE maxima. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5781

Categorization

• DEFINE: Clarifies the relation between SOAEs and SFOAE fine-structure maxima, key to interpreting which cochlear irregularity listeners weight.
• corroborated: 3 independent passages support this claim — Dijk, Pim van, Physiology, Psychoacoustics and…, 5763; Dijk, Pim van, Physiology, Psychoacoustics and…, 5781
• XREF: connects to: Spontaneous and evoked otoacoustic emissions likely share a single source — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing. Eberhard, Psychoacoustics- Facts and Models, 309; Otoacoustic emissions non-invasively probe outer hair cell function in humans. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3745; SFOAE amplitude maxima and minima differ by up to 30 dB (+3 more)
