  • Publication number: 20110235815
    Abstract: A method of processing an audio signal with a content is disclosed. The method comprises determining, based on an analysis associated with a missing fundamental phenomenon, a frequency region suitable for adding one or more harmonic tones of a fundamental tone, determining one or more spectral properties of the content within the frequency region, and adjusting operation of a function for adding harmonic tones based on the spectral properties. Corresponding computer program product, audio signal processing arrangement and electronic device is also disclosed.

  • Patent number: 7766120
    Abstract: The present invention relates to a cap (11) intended for use as hearing protection and adapted to enclosed the external ear of a user, characterized by at least one vibration-damping weight element (18, 38a-b) of the cap (11), which weight element is arranged so as to at least partly block an audio mode of vibration that would have existed in the cap in the absence of said weight element (18, 38a-b). The invention also relates to a method of producing such a cap, and use of the same.

  • Publication number: 20080013751
    Abstract: An electronic equipment is provided that includes an audio reproduction circuit for receiving an audio signal and reproducing the audio signal in accordance with a preselected audio frequency gain profile. In addition, the electronic equipment includes a volume gain control circuit for providing user adjustable volume gain to the audio signal reproduced by the audio reproduction circuit. The electronic equipment also includes an audio output for outputting the reproduced audio signal. The audio reproduction circuit alters the preselected audio frequency gain profile as a function of the user adjusted volume gain.

  • Patent number: 6427800
    Abstract: The invention relates to a sound-attenuating ear plug, comprising an elongate elastic body (103) adapted to be inserted at least partially into an auditory meatus. A foil (117) which is rounded in the longitudinal direction (115) of the body (103) and which is extended transversely of this longitudinal direction (115) is responsible for the major part of the sound-attenuating effect of the ear plug. The invention also relates to a method of manufacturing such an ear plug.

  • Patent number: 5815842
    Abstract: An earmuff incorporating elevated sound attenuation. The earmuff comprises an outer cup (10') which connects with a sealing part. Arranged within the earmuff are a plurality of separating partitioning walls (14) which extend from the bottom wall (16) of the cup towards the sealing part. The partitioning walls (14) may be integral with the cup (10') or formed separately therefrom and loosely fitted thereinto.
