20090245539 | USER ADJUSTABLE VOLUME CONTROL THAT ACCOMMODATES HEARING - A method for processing audio signals optimizes the listening experience for hearing impaired individuals to feel stigmatized by requiring them to employ special hearing-impaired equipment. A user actuated controller controls a mixture of a preferred audio signal and a remaining audio signal across a range sufficiently wide enough to encompass all individuals. The preferred audio is recorded and maintained separate from all remaining audio and delivered to the listener in a manner that maintains the separateness of the preferred audio and the remaining audio. The user actuated controller includes the capability of automatically maintaining the listener established ratio in the face of changes in the audio signal. The user actuated controller enables the user to specify a range about the ratio in which the audio may vary, which permits the listener to expand the audio across a continuous range to whatever dynamic range his hearing can accommodate. The controller automatically adjusts to changes in incoming audio. The controller can react to relatively slowly moving changes or prevent short bursts of sound in the remaining audio from modifying the signal levels. The combination of the above aspects provides a heretofore not possible listening experience that can accommodate the listening desires of all listeners. The combination of the ability to control the ratio of preferred audio to remaining audio and to specify the dynamic range about the ratio in which the audio may vary, coupled with the ability of the controller to automatically adjust the signal levels in response to sudden changes in incoming audio, provides a powerful user capability that truly optimizes the listening experience for any listener. | 10-01-2009 |
20100218775 | SOUND-ATTENUATING EARMUFF HAVING ISOLATED DOUBLE-SHELL STRUCTURE - An earmuff assembly with a double-shell structure is disclosed for use with a sound-attenuating circumaural headset. The earmuff assembly comprises a cup-shaped outer shell mounted on a resilient outer sealing ring and a cup-shaped inner shell mounted on a resilient inner sealing ring. By means of the two sealing rings the outer and the inner shells are brought into abutment with the head surface around an ear of a wearer. Both shells are structurally rigid. The sound attenuation performance is maximized by isolating the inner shell from the outer shell. | 09-02-2010 |
