40, 50, 60, 70 dB above sensation level (dB SL) are recommended, or above the normal hearing level (dB nHL) if there is a hearing loss. The different stimulus intensities should be administered in a randomized or pseudo-randomized order, with the intensity not being the lowest or the highest. Because of potential harm to the inner ear, the International Bureau for Audiophonology recommends to exclude subjects with an average hearing loss of 20 dB.

Since cortical EPs may undergo drastic changes just before, during and after a headache attack, it is crucial to mention the timing of recordings in relation to the headache.

The precise time windows for peri-ictal and inter-ictal vary with headache type. For episodic migraine, an interval of at least 72h from the last and before the next attack is generally accepted for "inter-ictal". In migraine with aura, it must be specified if the recordings are performed during the aura, during the headache or during the co-existence of both.
