  • Patent number: 11406292
    Abstract: A method for conducting a cross frequency simultaneous masking (xF SM) test begins with generating a signal probe and a masker probe. The center frequencies of the signal and masker probes are separated by a fixed frequency ratio. An xF SM curve is generated by sweeping the signal and masker probes across a given frequency range, while maintaining the fixed frequency ratio between the two. While sweeping, the masker probe is maintained at a pre-determined masker amplitude or a series of pre-determined masker amplitudes. The amplitude of the signal probe is adjusted in response to a series of user inputs, which are then interpolated to generate the xF SM curve. Additionally, while sweeping, the signal probe can be maintained at one or more pre-determine amplitudes and the amplitude of the masker probe adjusted in response to user inputs, which are then interpolated to generate the xF SM curve.

  • Patent number: 11399239
    Abstract: An audio calibration system applied to a hearing detection device includes an audio generator, a cloud server, a mobile computing device, and an audio playback unit. The audio generator plays a first test sound. A sound pressure level of the first test sound at any frequency between 500 Hz and 4000 Hz is Z. A computing unit of the mobile computing device generates a first value X after receiving the first test sound through a microphone, and the computing unit generates a second value Y after receiving a second test sound through the microphone. The audio playback unit receives an audio command from an audio control interface, and plays the second test sound to the microphone. The computing unit obtains a calibration value through a relational expression of Z+(Y?X).

    Abstract: A method and system for automatically configuring a medical device that is at least partially implanted in a human recipient and that includes a transducer arranged to stimulate a physiological system of the recipient, such as a middle-ear implant for instance. The energy level of a signal provided to drive the transducer is progressively increased until there is a threshold electrical change indicative of a threshold change in impedance of the transducer. In the context of a middle-ear implant, for instance, the threshold electrical change indicative of the threshold change in impedance of the transducer may be indicative of the acoustic reflex. The energy level of the signal at that point is then used as a basis to set an operational parameter of the medical device, such as a comfort-level of the middle-ear implant for instance.

  • Patent number: 8398562
    Abstract: An ear canal pressurization device optimized for aural acoustic immittance testing is disclosed. Changes in volume of a first flexible chamber, due to motor movement, produce changes in ear canal pressure based on Boyle's law. A vent may be opened to allow ear canal pressure to gently equalize to ambient air pressure or to generate ear canal pressure sweeps free of pressure baseline offset. The vent may be closed to set a static ear canal pressure or to generate ear canal pressure sweeps with an incidental baseline offset. The vent may be controlled to generate ear canal pressure sweeps with an intended baseline offset. The device produces ear canal pressure proportional to drive voltage, so any desired pressure versus time function can be generated by applying a coil driving voltage with the appropriate amplitude versus time function.

  • Patent number: 7793545
    Abstract: An audiometer including a processor controlled test signal generator is adjustable so as to produce a uniform output signal when coupled with a transducer load. Each transducer set to be used with the test signal generator includes recordable indicia in written or electronic form, upon which correction values for adjusting the electronic signal output of the audiometer module to produce a desired sound output from the each transducer in the transducer set. When the transducer set is connected to the audiometer module, the correction values are either retrieved automatically from the electronic indicia, which may be an EEPROM, or are input to the processor manually by a user through an interface such as a keyboard. These correction values are then used by the processor to dynamically adjust the output of the audiometer to correct for sound output response deviation of each transducer in the transducer set.

  • Patent number: 7780609
    Abstract: A method of detecting a change in hearing of a user includes providing a sound generating device for providing both a content audio signal and a hearing test audio signal. The sound generating device is used to provide hearing test audio sounds of different loudnesses around a threshold of hearing of the user. None of these sounds is calibrated to a pre-specified decibel level. A first threshold of hearing is determined at a first time and a second threshold of hearing is determined at a second time. The first threshold of hearing is compared with the second threshold of hearing.

  • Publication number: 20090288489
    Abstract: The present invention relates to a pure tone audiometer, and more particularly, to a pure tone audiometer with automated masking which is capable of automatically performing air-conduction and bone-conduction hearing tests and automatically performing a masking test, if necessary, so that a person obtains an accurate pure tone hearing threshold without others' assistance. The pure tone audiometer of the present invention can accurately perform the pure tone hearing test with automated masking without assistance from a doctor or an audiologist. Thus, with the pure tone audiometer, people can easily check their hearing ability for prevention and early detection of hearing loss and take swift action to cure hearing loss.

  • Patent number: 7610810
    Abstract: Embodiments include an acoustic source for use in a hemi-anechoic chamber comprising a source assembly and a waveguide assembly for producing sound outside of a measurement hemisphere and channeling the sound into the measurement hemisphere. A waveguide end from which sound emanates is positioned close to the reflecting plane of the chamber and can approximate a point source.

  • 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: 7529379
    Abstract: A system and method is provided for confirming the identity of a user, where the confirmation is made using biometric data. The system includes an internal speaker having an audio port, which is positioned within the ear of the user, and is adapted for producing a signal having one or more frequencies. The system further includes an internal microphone having an audio port, which is positioned within the ear of the user, and is adapted for detecting a resulting signal including the signal produced by the internal speaker and any corresponding signal reflections. A determination is then made as to whether the resulting signal detected by the internal microphone matches the corresponding predetermined expected signal, based upon a prestored hearing profile.

  • Patent number: 7509253
    Abstract: A device which uses an input of speech and measures latency between stimulus and response. The device generally includes an input transducer for converting a stimulus speech sound into an electrical signal and transmits the electrical signal to an electric circuit. In the preferred embodiment, the electric circuit includes a central processing unit which utilizes delay time counters to measure the length of time between signals. A second input transducer is used to convert a response speech sound into an electrical signal and transmits the electrical signal to the electric circuit. Each input transducer operates on a separate channel, so that the central processing unit may easily distinguish between stimulus sounds and response sounds.
