Abstract: A method of manufacturing an acoustic seal for a CIC hearing aid has the steps of: embedding sacrificial particles of 50 ?m to 250 ?m into a silicone rubber matrix, the concentration and size of the sacrificial particles being selected to achieve a porosity of at least 40%; molding the silicone rubber matrix using a mold and curing the silicone rubber matrix; removing the sacrificial particles from the silicone rubber matrix by leaching out the sacrificial particles in a solvent; and drying the silicone rubber matrix. The seal is to surround at least part of the hearing aid and by selection of the size and/or concentration and/or the distribution of the sacrificial particles, to provide for an acoustic attenuation of at least 20 dB in a frequency range between 200 Hz and 6 kHz, with a compliance of at least 50 mm/N when the hearing aid is inserted into the ear canal.
