[Frequency analysis of the various stimuli used in brain stem electric response].
It was our aim to analyse the frequency spectra of these different stimuli in order to select the most suitable stimulus as one wants to apply BER either as objective audiometry or as oto-neurological means of diagnosis. The kind of stimulus is important because its characteristics will condition the parameters of the electro-physiological response. As oto-neurological means of diagnosis, it will be preferable to use the shortest possible stimulus and by no means a filtered stimulus. As objective audiometry, a long stimulus will be used with a less rough onset, which thus presents a narrow frequency spectrum and still creates a clear P5/FFP7 complex. For both applications the Logon offers the best compromise.
