A system having a scope with a longitudinal length extending between a proximal end and a distal end includes a plurality of markers spaced along the longitudinal length. The system also includes a disassociation and positioning device that is configured to enhance unsedated transnasal endoscopic procedures by at least partially occluding the vision of a patient while enabling body cavity access, and optionally record and sense body functions such as temperature, heart rate and oxygenation of the blood stream. The system further includes a sensor integrated into the distraction device, wherein the sensor is configured to detect the markers on the longitudinal length of the scope.

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.

A system and method for automatically and dynamically controlling the output (e.g., volume) of an audio headphone device is disclosed, which includes detecting the invocation of the acoustic reflex with an audio headphone device. The disclosed system can measure the response of the tympanic membrane and middle ear to various SPL and frequencies. That information may be used for automated or customized warning or limiting levels either within the headphone, or at the audio playback device.

An in-ear device includes a tympanic membrane measurement unit (TMMU) and an audio package configured to emit sound. The device is configured to measure a movement of a tympanic membrane in an ear using the TMMU caused by external sound received by the tympanic membrane, analyze at least the movement of the tympanic membrane measured by the TMMU using a predictive model trained by a machine learning technique to generate a waveform of cancellation sound that will destructively interfere with the external sound when received by the tympanic membrane, and output the cancellation sound from the audio package to destructively interfere with external sound received by the tympanic membrane.

A hearing device has an input transducer, a signal processor for signal amplification and generation of an output signal, and an output transducer for converting the output signal into a sound signal. In a fitting method for fitting the hearing device, at least one test measurement is carried out in which a test signal is generated as an acoustic signal, and in which the hearing device user assesses the resulting sound signal as a test result. A fitting formula is determined based on the test result, and the signal processing device is set based on the fitting formula such that if, during operation of the hearing device, a rise time of a signal start of the input signal is less than or equal to a stored threshold value, then the signal start of the output signal is amplified by a higher gain value than the remaining output signal.
