The auditory deprivation caused by gradual hearing loss makes it difficult for many individuals to accept amplification immediately. This is one reason why first-time wearers often complain that everything sounds too loud or too shrill. This is also one of the reasons why many hearing instruments end up "in the drawer". In order for customers to become acclimatized to amplification, wearing new hearing instruments must be comfortable, not only physically, but also in regard to sound quality. First-time users typically appreciate any means to suppress unwanted noises since they experience the most difficulties in noisy situations. Experienced wearers, however, know that besides noise reduction, feedback suppression, bandwidth extension, and restored localization is also important to improve Sound Comfort (Kochkin 2005).
