Abstract: Earmuff and method for changing the noise attenuation characteristic of an earmuff. The change is obtained by providing foam-filled sealing ring of the earmuff in the annular covering thereof with a large number of ventilation apertures which are uniformly distributed along the sealing ring, thereby affecting the air spring action of the sealing ring. The ventilation apertures communicate with the environment without communicating with interior of the earmuff. By reducing the air spring action to a considerable extent, the low frequency attenuation is improved. The communication with the environment provides "acoustic ducts", particular by using special ventilation ducts which can be dimensioned to give a selective noise transmission, dependent on the duct resonance, into the sealing ring, thereby selectively affecting the noise attenuation characteristic.

Abstract: A headphone has an electroacoustic transducing device for converting an electrical signal to an acoustic signal, a housing for housing the electroacoustic transducing device, a flexible support member of which one end is fixed to the housing, and a vibration member disposed at the other end of the flexible support member. The vibration member generates primary vibrations by an electrical signal having a specific correlation to the electrical signal supplied to the electroacoustic transducing device. The resulting primary vibrations are transmitted through the flexible support member to the housing which then generates secondary vibrations. Unlike the impact vibrations of the primary vibrations, the secondary vibrations felt through the entire housing provide pleasant vibrations similar to air vibrations of the low bass sounds simultaneously to the corresponding low range sounds reaching the eardrum.
