Click-evoked otoacoustic emissions (CEOAEs) were recorded from the right ear of eight native Mandarin speakers and eight native English speakers in conditions with and without a contralateral suppressor. The CEOAE stimuli consisted of linear clicks presented at 65 dB peSPL. Two types of 70 dB SPL contralateral suppressors (white noise and synthesized Mandarin tone) were utilized. The amount of contralateral suppression was quantified in nine 2-ms time bands. No significant differences in contralateral suppression occurred between language groups for the white noise suppressor. Notably, significantly more contralateral suppression was evoked by the synthesized Mandarin tone in native Mandarin speakers compared to native English speakers.
