Abstract
An in-the-ear hearing aid has a collar which can form a flexible seal in the bony part of the ear canal so as to reduce the occlusion effect. The collar comprises a tubular portion which is engageable against the wall of the ear canal, a fixing portion and a curved sealing portion. Owing to the use of this collar it is not necessary to make a mold of the bony part of the ear canal. This collar enables the hearing aid to be constructed in a manner such that it can be inserted so deep into the ear.
