Research Abstract

We analyzed the ASSR signal in contrast to the background noise at different sleep stages. The noise level was especially low in stage N3 (deep sleep) and REM (rapid eye movement sleep), whereas there was no significant difference in the response signals among sleep stages. Consequently, the signal-to-noise ratio (SNR) was high in both stage N2, N3 and REM. Hence, sleep stage should be taken into account when estimating the hearing level fromASSR.
