  • Patent number: 10560786
    Abstract: A speech intelligibility system. Embodiments comprise a talker unit, a listener unit and an earpiece. The talker unit includes a microphone to receive audible speech content and to produce electrical signals representative of the speech content, and a transmitter coupled to the microphone to produce wireless transmissions containing the speech content. The listener unit includes a receiver to receive the wireless transmissions and to produce electrical signals representative of the speech content. At least one of the talker unit and the listener unit includes an amplifier to amplify spectral components of the speech content within a frequency range having a lower end between about 800 Hz and 1,700 Hz and an upper end between about 7,000 Hz and 11,000 Hz. The earpiece is coupled to the listener unit and includes a speaker to produce audible speech content having the amplified spectral components and a tube to direct the audible speech content from the speaker toward a user's ear canal.
    Type: Grant

  • Patent number: 9566023
    Abstract: The present technology relates to an earphone apparatus adapted for use in audiometry examinations. The earphone apparatus comprises a housing and a receiver having an acoustic output adapted to connect with an audio signal source. The earphone apparatus can also include a circuit board with an electrical equalization network connected to the receiver. A coupling can be connected to the acoustic output of the receiver. A sound tube can be connected to the acoustic output and extends out from the housing to an ear piece. The earphone also includes a resonance cancellation assembly comprising a damping chamber and a tubing section acoustically connecting the damping chamber to the coupling. The damping chamber can provide an acoustic compliance to the sound delivered by the receiver. The earphone can also comprise an electrical connector with a protector that is adapted to connect with a female connector delivering electrical power.
