Auditory Electrophysiology Lab

All-in-One Solution for Auditory EP and OAE Acquisition

A full range of objective and subjective techniques for the diagnostics of hearing and balance is in the one compact-sized device now! Using this device, you can perform ABR, ASSR, multi-ASSR, MLR, LLR/CAEP, TEOAE, DPOAE, SOAE, ECochG, VEMP, P300, MMN, pure tone audiometry techniques easily.

Automatic Multi-ASSR Test

Multi-ASSR test implemented in the Neuro-Audio system reduces the test duration due to the automatic intensity switching for hearing threshold search, stimulation of both ears simultaneously by 8 frequencies (4 in each ear, from 500 Hz to 4000 Hz), and frequency-specific Chirp stimulus which takes the cochlear anatomy into account to increase the response amplitude. The test result is represented as the estimated pure tone audiogram used further for hearing aid fitting.

VEMP with Biofeedback

Dizziness is one of the main reasons for visiting a doctor (up to 30–40% of all visits according to Neuhauser 2005, Geser & Straumann 2012). Neuro-Audio can also be used successfully in the diagnosis of vestibular disorders.

The system ensures full state-of-the-art support of VEMP tests, including VEMP with biofeedback, VEMP amplitude scaling by mean EMG activity level, and also a unique function of EMG histogram with post-hoc analysis (important for children). Supported techniques: cervical and ocular VEMP tests (cVEMP and oVEMP).

Diagnosis of Meniere's Disease

Electrocochleography (ECochG) is used to diagnose Meniere's disease and endolymphatic hydrops. In addition to the traditional SP/AP amplitude ratio calculation (which has a low sensitivity to this pathology), the Neuro-Audio software calculates SP/AP area ratio. That’s why the system is one among the few devices in the world that can significantly increase the sensitivity of the technique in the diagnosis of Meniere's disease.
