Abstract
The amplitudes and detection thresholds of click-evoked otoacoustic emissions (c-EOE) and SFE were determined in 58 patients suffering from acoustic trauma. A multivariate statistical analysis was performed in order to investigate the relationships between EOE around 0.75, 1 and 2 kHz, and the various audiometric thresholds. Only one significant correlation was found between EOE threshold at F and auditory threshold at 2F, suggesting that some EOE properties are not frequency-specific. It is shown that the alternative hypothesis assuming that EOE amplitudes are proportional to the total number of residual active sites along the basal cochlea provides a much better fit to experimental data and is consistent with several models and experimental results.
