  • Title: Programmable auditory stimulus generator and electro-acoustic transducers--measurements of sound pressure in an artificial ear and human ear canal.
    Author: Maurer K, Schröder K, Schäfer E.
    Journal: Electroencephalogr Clin Neurophysiol; 1984 Jul; 58(1):77-82. PubMed ID: 6203706.
    Abstract:
    The measurement of sound pressure wave forms of different headphones resulted in considerable differences in an artificial ear and in the external auditory canal in man. This concerns, in particular, the pattern of stimuli used to elicit the auditory nerve and brain-stem auditory evoked potentials. By varying the electrical input to the headphones by means of a programmable stimulus generator, it can be shown that the sound pressure wave form can be influenced considerably.
