Intended Use

The Integrity V500 with DPOAE and TEOAE test options is indicated for use when it is necessary for a trained health care professional (for example, an Audiologist) to measure or determine cochlear function by measuring, recording, and displaying otoacoustic emissions. This device does not measure hearing, but helps to determine whether or not a hearing loss may be present, requiring further evaluation. DPOAE and TEOAE tests do not measure hearing per se, but measure whether or not the cochlear hair cells are functioning. This device does not determine hearing levels, but allows the operator to establish specific pass or refer criteria. The Integrity V500 with ABR/ASSR options is indicated for auditory evoked potential testing as an aid in detecting hearing loss and lesions in the auditory pathway. The Integrity V500 is a prescription device. The labeling, instructions and user operations are designed for trained professionals.

Device Story

Integrity V500 is an electrophysiological diagnostic system for auditory assessment. It measures otoacoustic emissions (DPOAE/TEOAE) to evaluate cochlear hair cell function and auditory evoked potentials (ABR/ASSR) to detect hearing loss or auditory pathway lesions. Operated by trained professionals (audiologists) in clinical settings. Device records physiological signals, processes data to display test results, and allows operators to set pass/refer criteria. Provides objective data to assist clinicians in identifying potential hearing impairment, necessitating further diagnostic evaluation. Does not directly measure hearing thresholds.

Technological Characteristics

System performs DPOAE, TEOAE, ABR, and ASSR testing. Utilizes signal acquisition and processing for otoacoustic emissions and auditory evoked potentials. Designed for professional clinical use.

Indications for Use

Indicated for use by trained healthcare professionals (e.g., audiologists) to assess cochlear function via otoacoustic emissions (DPOAE/TEOAE) and to aid in detecting hearing loss and auditory pathway lesions via auditory evoked potential testing (ABR/ASSR). Prescription use only.

Regulatory Classification

Identification

An evoked response auditory stimulator is a device that produces a sound stimulus for use in evoked response measurements or electroencephalogram activation.
