Conditions
Brief summary
The purpose of this study is to examine two frequency lowering techniques in case of audibility, recognition, distinction, discriminability and sound quality.
Detailed description
This is a controlled, single blinded and randomised comparative study which is conducted monocentric at Hoerzentrum Oldenburg, Germany. The focus is to test two frequency lowering techniques with an amount of 30 moderate to severe, symmetrically sensorineural hearing impaired adult subjects. The subjects, all of them native German speakers, individually conduct a number of laboratory standard tests and home trials (questionnaires) during 6 months including seven appointments of 2 hours.
