Abstract: Fourteen experienced users of bone-anchored hearing aids conducted paired comparisons of sound quality and speech intelligibility for 6 and 4 different stimuli respectively in the Classic 300 and a bone-conduction hearing aid with a steel clip. Ten paired comparisons were made for each stimulus. The patient selected the best hearing aid and rated the chosen hearing aid on a scale of 'somewhat better', 'better' and 'much better'. The Classic 300 obtained a positive assessment in terms of sound quality and speech intelligibility far more frequently. All the patients chose the Classic 300 as the best hearing aid when they assessed the sound quality of the classical music stimulus.
