Transiently Evoked Otoacoustic Emissions in Children with Otitis Media with Effusion

Table 1

Means and levels of statistical significance (P) of pure-tone thresholds and signal-to-noise ratios of transiently evoked otoacoustic emissions (TEOAEs), comparing the ears of patients and the ears of controls.
