A patient is offered a schedule of wearing their hearing aid ensuring gradual adaptation to it. If the patient starts permanently wearing the hearing aid, unfamiliar sound may cause a headache, and as a result the user refuses to wear a hearing aid despite the fact that it helps. Surdo-teachers often run a quick preparation course for the patients. As a rule, users have inflated expectations of using hearing aids. They expect that hearing aids will help them to hear in the same way as before hearing loss, but it is not like that. Conducted trainings help hearing aid users to get accustomed to new sound feelings. A user is strongly recommended to regularly visit a surdologist, including for the purposes of additional hearing aid adjustment.
