It utilizes Auditory Steady State Response (ASSR) modality to record and analyze human physiological data. The system delivers continuous frequency and/or amplitude-modulated tones as stimuli; it can combine multiple stimuli simultaneously to assess responses across various frequencies. Scalp electrodes capture evoked responses, which are analyzed to predict frequency-specific behavioral hearing thresholds. The device is intended for use by clinicians to assist in the diagnosis and treatment of audiovestibular and hearing-related disorders, specifically benefiting patients unable to provide reliable behavioral responses. ## Clinical Evidence No clinical data provided; device relies on established ASSR technological principles for physiological data recording and analysis. ## Technological Characteristics Windows-based software application; utilizes Auditory Steady State Response (ASSR) modality; hardware platform: Navigator Pro; stimulus: continuous frequency and/or amplitude modulated tones; input: scalp electrode physiological signals. ## Regulatory Identification An evoked response auditory stimulator is a device that produces a sound stimulus for use in evoked response measurements or electroencephalogram activation. ## Predicate Devices - [K021895](/device/K021895.md) Master, a Modification to Bio-logic Evoked Potential ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Potential | | Device Description: | Master II Evoked Response System is a Windows® based
software application for use with the Navigator Pro hardware
platform using Auditory Steady State Response Modality for
the recording and analysis of human physiological data for
the purpose of neurological diagnosis and treatment of
audiovestibular and hearing related disorders. | | Intended Use: | The Master II Evoked Response System is intended for the
recording and analysis of human physiological data
necessary for the diagnosis of audiovestibular and hearing-
related disorders. | | Technological
Characteristics: | Master II is a Windows® based application using Auditory
Steady State Response (ASSR) modality. ASSR is used to
predict frequency-specific behavioral hearing thresholds
particularly for patients who cannot provide a reliable
behavioral response. The ASSR technique uses a
continuous frequency and/or amplitude modulated tone as
the stimulus and can combine several stimuli together | {1}------------------------------------------------ December 21, 2007 Bio-logic Systems Special 510(k) Master II Evoked Response System > simultaneously to assess responses to various frequencies all at the same time.
