I am still unsure about who discovered SOAEs, and I would be grateful if one of you could send me a PDF of the following paper:
D. T. Kemp, "Evidence of mechanical nonlinearity and frequency selective wave amplification in the cochlea", Arch. Otolaryngol. 224 (1979) 37-45. That journal appeared up to 1989, and was then replaced by a journal with a similar name.
With many thanks, sincerely,
Dr. phil. nat.,
