An Extraordinary AEP Product

by Greg Ollick, Sr., M.A.


"We brought the new Integrity Gen 2 device into environments loaded with electro- magnetic interference which is very hostile to AEP testing, and the Gen 2 system was virtually unaffected....We were able to get clear, clean ABR and ECocGh responses with the patient awake, sitting up and occasionally talking, and we obtained all of this in substantially less time than with any other system."

Integrity V500 System

Superior auditory evoked response detection


Clinics around the world report the practical benefits of the Integrity™ V500 System for auditory evoked potentials (AEP) and otoacoustic emissions (OAE) measurements. The unique advantages of the Integrity V500 System have made it the #1 Awake ABR system for clinics specializing in pediatric audiology, while providing equally valuable benefits for clinics serving general and special needs adults, as well as the geriatric population.


Integrity™ combines new signal processing technologies, improved amplifier design and wireless capabilities to produce clear recordings with or without sedation. With this innovative technology, Integrity™ minimizes patient risk, expedites the early detection of hearing loss, significantly reduces loss to follow-up issues for newborn hearing screening programs, and demonstrates reliable performance in less-than-ideal clinical environments.

Superior ABR detection without sedation


Patented and award-winning technologies built into the Integrity V500 System enable clinical practitioners to obtain accurate and reliable ABR measurements without sedation or anesthesia. The ability to perform non-sedated ABR assessments is essential to maximize patient safety, assess high-risk patients, reduce wait times for diagnostic assessments, ease caregiver anxiety, and significantly reduce healthcare costs. ABR assessments without sedation make it ideal for use in tele-health and the provision of assessments via tele-audiology.


The Integrity V500 System further enables practitioners to assess young patients while they are awake, without the need to employ inconvenient and, oftentimes, ineffective sleep deprivation methods. No other AEP product on the market has the same combination of technologies to facilitate Awake ABR.

Reliable results in difficult environments


Sources of electromagnetic inteference in the environment typically make it difficult to collect reliable AEP measurements. It is common for audiologists to spend more time reducing environmental noise to acceptable levels than actually recording data. Studies report clear advantages of the Integrity V500 System over popular AEP equipment when testing in environments with high electromagnetic interference. Integrity has been found to be less susceptible to electrical artifact and power line noise, with the the ability to determine more accurate hearing threshold levels than other products in difficult environments such as the NICU.


The need to use shielded rooms or special equipment is virtually eliminated. And, with its immunity to electromagnetic interference, Integrity V500 System is an invaluable tool for intraoperative monitoring in the noisy operating room. Whether in the NICU, operating room, office, waiting room, or other suboptimal conditions, Integrity technology is effective in managing electrical artifacts -- saving busy practitioners valuable clinical time, and budget-conscious clinics valuable resources.

Convenient, portable, wireless recording


Wireless technology integrated into the Integrity V500 System has convenient and practical benefits. The VivoLink™ wireless recording technology records the ABR and sends the data wirelessly to the Integrity computer - up to a distance of 30 feet (10 meters) - for further processing and storage. This provides patients the freedom to move, untethered to the computer. Infants can be conveniently tested while in their mothers' arms, in an isolette, in a car seat or stroller, or in similar comforting positions. Straps that attach to the VivoLink enable the unit to be worn as a back-pack on a young child, or around the neck of an older child or adult.

Built-in tools that simplify data acquisition and interpretation


Unlike conventional systems that employ artifact rejection to discard noisy sweeps, the Integrity V500 System uses sophisticated SOAP™ Adaptive Processing -- no sweeps are rejected so data can be collected and analyzed in less time.


The replicability of AEP responses can be readily visualized with the help of dual buffers which enable the visual inspection of waveforms generated from different sweeps without repeating the collection protocol. Residual noise in the response can also be visually inspected with the help of the buffers. In addition, objective statistical measures are calculated to further enhance confidence in waveform interpretation.


Alternating split polarity is available to detect the cochlear microphonic in a response. To examine specific areas of the waveform, the recording window can be adjusted to focus on the area of interest.
