Probe placement for sound pressure measurements in the aided ear.
Sound pressure measurements at the tympanic membrane in the aided ear were performed with application of the probe either through a 2 mm ventilation canal in the ear mould or in the space between the mould and the auditory canal. For frequencies above 500 Hz, concordant results were obtained by the two methods. The latter method has the advantage of being independent of the shape of the mould and the ear.
