  • Patent number: 7574007
    Abstract: A stimulus analysis system and artifact rejection method are disclosed. The method may be used in many applications, such as, for example, DPOAE testing, TEOAE testing, BAER testing, ultrasound, MRI, RADAR, GPS, EEG, EKG, or communications. In one embodiment, a system receives a signal, and depending on the noise power of the signal, the signal is placed in one of a plurality of buffers or is discarded. This process is repeated. The combination of buffers that yields the lowest noise power is then selected. The selected combination of buffers may then be used to calculate a signal to noise ratio, which may be used to determine whether the signal received is acceptable, indicating, for example, that a test has been passed or failed.

  • Patent number: 7551940
    Abstract: A two-way voice communication device which provides a high-level of acoustic noise reduction is disclosed. A resilient ear tip provides acoustic isolation and secures the earphone within the ear canal of the user. The ability to rotate the earphone within the ear canal allows the user to easily position an attached microphone. The audio signals may be conveyed by an included radio frequency receiver and radio frequency transmitter, or the earphone may be connected to an electrical audio device using a multi-conductor cable. Audio signals may be conveyed to one or both ears of a user. A switch to mute the audio signal from the microphone, or for supporting a push-to-talk mode of operation, may be included in the earphone housing, or on the cable.

  • Patent number: 7460677
    Abstract: A directional microphone array system generally for hearing aid applications is disclosed. The system may employ a broadside or an endfire array of microphones. In either case, the signals generated by the microphone are added using a plurality of summation points that are connected together via a single signal wire or channel. In the case of the endfire array, all but one of the signals is delayed so that the summation of the signals are in phase. The summation of the signals is then used to generate an output signal for a speaker of a hearing aid or the like.

  • Patent number: 7452337
    Abstract: A hearing screener apparatus is disclosed and may include a housing and a testing probe operatively coupled to the housing. The testing probe may generate electrical signals based on otoacoustic emissions of the inner ear of a test subject, when the testing probe is inserted into the ear canal of the test subject. The hearing screener apparatus may also include a housing, a digital signal processor (DSP) within the housing, and a testing probe operatively coupled to the housing. The DSP may generate measurement data based on the electrical signals. At least one microphone may be mounted with the testing probe for generating the electrical signals based on the otoacoustic emissions. The testing probe may be vibrationally isolated from the housing. The testing probe may be elastically coupled to the housing. The hearing screener apparatus may also include an isolation body elastically coupled between the testing probe and the housing.

  • Patent number: 7298858
    Abstract: An improved insert earphone for audiometric testing is provided, having a housing, a receiver located within the housing, a flexible eartip located externally to the housing, and a tube nipple acoustically coupled between the receiver and the flexible eartip. The flexible eartip has a flexible tube portion that is coupled to an output end of the tube nipple, which may be rigid. The housing and tube nipple are configured and arranged such that the angle between a longitudinal axis of the tube nipple and the vertical axis is obtuse, minimizing the stress on the ear canal when the flexible eartip is inserted therein. An acoustic damper may be located at or near the input end of the tube nipple to prevent ear wax from clogging the damper and minimize the need for damper replacement.

  • Patent number: 7269262
    Abstract: A hearing test device and method are disclosed which involve the placement of a testing probe in the ear canal of a test subject. The device analyzes responses to stimuli applied to the ear canal to determine whether the testing probe has been properly placed in the ear canal. The device may determine, for example, whether the probe is stable, whether it is sealed in the ear canal, whether the resulting volume of the ear canal is acceptable, and/or whether the stimuli delivery system is blocked in any way. If the device determines that the testing probe has been properly placed in the ear canal, the device automatically starts a hearing test without requiring any operator input.

  • Patent number: 7245728
    Abstract: A microphone assembly generally for hearing aid and communications applications is disclosed. The microphone assembly operates in both directional and non-directional or omni-directional modes. The microphone assembly has front and rear sound inlet tubes, and an actuator switch that may be moved between a first position in which the rear tube is plugged, defining the omni-directional mode, and a second position in which the rear tube is unplugged, defining the directional mode. Circuitry senses the position of the actuator switch and selects a microphone output based on the position sensed.
