Zusammenfassung:An airborne sound transducer comprises an electromechanical transducer, an air impedance matching layer arranged on an acoustically active surface of the electromechanical transducer, and a cover arranged on the air impedance matching layer, an outer surface of the cover forming an exposed acoustic area of the airborne sound transducer. The outer surface is hydrophilic such that a contact angle of water on the outer surface is less than 60°.
