The effect of coffee on TEOAE and contralateral suppression of TEOAE

The present research was carried out to investigate the effect of coffee on the amplitude of transient evoked otoacoustic emission (TEOAE) and the magnitude of contralateral suppression of TEOAE. Participants were randomly assigned in to two groups, namely 'coffee-first' group and 'milk-first' group. The TEOAEs were recorded on two separate days. On day 1, the TEOAE was recorded before and after consumption of coffee among participants in coffee-first group and before and after consumption of milk among participants in milk-first group. After 1 week, the TEOAE was recorded before and after consumption of milk among participants in coffee-first group and before and after consumption of coffee among participants in milk-first group. Further, the TEOAE was recorded with and without presenting white noise to the contralateral ear of participants for measuring the contralateral suppression of TEOAE. The TEOAE was recorded using Echoport ILO292-II otoacoustic emission system (Otodynamics Ltd., Hatfield, UK). The global amplitude of TEOAE and magnitude of contralateral suppression of TEOAE across conditions for both ears is provided in the dataset.
