The Allen-Fahey experiment extended.
An ingenious experiment has been performed by Allen and Fahey [J. Acoust. Soc. Am. 92, 178-188 (1992)], in which they attempted to estimate the gain of the cochlear amplifier by comparing responses to the 2 f1-f2 distortion product (DP) in the outer ear canal (otoacoustic emissions) and from an auditory-nerve fiber. Results were essentially negative: no evidence of cochlear amplification was fo...
متن کاملAllen-Fahey and related experiments support the predominance of cochlear slow-wave otoacoustic emissions.
Originally proposed as a method for measuring the power gain of the cochlear amplifier, Allen-Fahey experiments compare intracochlear distortion products and ear-canal otoacoustic emissions (OAEs) under tightly controlled conditions. In this paper Allen-Fahey experiments are shown to place significant constraints on the dominant mode of reverse energy propagation within the cochlea. Existing Al...
متن کاملFond Memories of John Fahey.
John Fahey was one of the first investigators to study the then-new acquired immune deficiency syndrome (AIDS). He made major contributions to the design of the Multicenter AIDS Cohort Study (MACS), and vigorously promoted novel and high-quality science as the MACS evolved. His contributions are highly valued.
متن کاملDouble-layer formation in the extended Franck-Hertz experiment.
A model is developed which explains the collective plasma phenomena associated with the extended Franck-Hertz experiment described in an earlier paper by Nicoletopoulos [Eur. J. Phys. 23, 533 (2002)]. The particular focus is on the formation of the free steady-state monotonic double layer. The approach used is a Bernstein-Greene-Kruskal theory in which one postulates the space potential and a s...
متن کاملAllen Schick
During the past decade New Zealand has introduced far-reaching reforms in the structure and operation of government departments and agencies. This model has attracted interest in developing countries because it promises significant gains in operational efficiency. But developing countries, which are dominated by informal markets, are risky candidates for applying the New Zealand model. The auth...
