Abstract
The relaxation dynamics of spontaneous otoacoustic emissions (SOAEs) i nteracting with an external tone have been successfully described usin g a van der Pol limit cycle oscillator model [Murphy et al., J. Acoust . Sec. Am. 97, 3702-3710 (1995) and Murphy ct al., J. Acoust. Sec. Am. . 97, 3711-3720 (1995)]. Data were collected for an SOAE interacting w ith a single-frequency ipsilateral suppressor. Transitions between dif ferent suppressed states were achieved by adding or removing signal at the suppressor frequency. The relaxation dynamics of the van der Pol model provided a good fit to the data. (C) 1996 Acoustical Society of America.
