title: Bilateral hearing aids--effects and consequences from a user perspective.
abstract: The present study assesses the experiences with bilateral amplification in a group of 144 people provided with two hearing aids between May 1994 and July 1997. Two-thirds of the participants preferred to use both prescribed hearing aids. The participants reported that they used their hearing aids frequently. Bilateral amplification was appreciated especially for recognizing speech, for sound localization and for superior sound quality. Situations in which the subjects showed the highest appreciation of two hearing aids were when attending lectures and theatre performances and for communication in noisy background situations. There were statistically significant differences between users of bilateral and unilateral hearing aids regarding judgement of sound quality of hearing aid processed signals and localization ability in favour of bilateral hearing aid amplification. The self-assessed advantages of bilateral amplification demonstrated in this study should motivate a generous prescription strategy of two hearing aids.
