Abstract
A membrane for covering an opening in a hearing aid is produced by a process of electrospinning fibers to form a non-woven structure. The electrospinning is adjusted in such a way that the various requirements of the membrane are fulfilled in the hearing aid, in particular with respect to water and dirt-repelling properties and acoustic permeability. The membrane is fixed by way of example in the form of a covering, in which the membrane is held by a holding frame, by a fixing device in front of the opening in the hearing aid. The membrane is adapted by way of example so as to be permeable to sound in order to use it for covering a noise admittance or exit opening of the hearing aid.
