Abstract
A sound damping filter for an ear protector placeable in the auditory duct of a person. The sound damping filter comprises a sound damping canal with a passage extending from a sound inlet opening to a sound outlet opening. The passage of the sound damping canal is closed off by means of an air-permeable, sheetlike membrane, such that transport of air through the filter is possible. The invention also relates to an ear protector and a method for manufacturing a membrane for a sound damping filter.
