✦ Synopsis

The acoustic blink reflex was examined in 26 subjects with open eyes and 20 subjects with closed eyes by means of an electrooculogram. Amplitude and excitability are highly dependent on the loudness of the stimulus used and on the opening or closure of the eyelids. Particularly if the eyes are closed, it may be necessary to use a stimulus of high (105-110 dB SPL) intensity (hand-clapping is often not loud enough). If an acoustic blink reflex can be elicited, it can be assumed that certain pontine and mesencephalic structures are intact.
