ABSTRACT:
An acoustical device for the reception of sound such as music by humans. The device includes a stereo headset having an acoustic passage and terminal earphones at each end of the headset. The headset is mountable on the head of a human so that the terminal earphone at each end of the headset is disposable over an ear of a human. The acoustic passage is hollow and extends from one side of the headset to the other, so that sound emanating from one terminal earphone is channeled from one ear of a human to the other ear, and so that sound emanating from the other terminal earphone is channeled from the other ear of a human to the one ear. Mechanical sound inhibitors are provided. A first inhibitor is disposed in the acoustic passage, so that various ratios of direct sound to ambient sound reflected through the acoustic passage may be mixed and received in an ear of a human as a mixed sound. A second inhibitor is disposed in each end of the headset within each of the terminal earphones, so that sound emanating from the terminal earphones may be varied in amplitude. A sound emitting element is preferably disposed centrally in the acoustic passage.
