Complete Solution for ABR Testing

Neuro-Audio/ABR is the result of our best experience in the development of accurate neurophysiological equipment for ABR testing. The recording is made with 1 or 2 channels for air- or bone-conduction.

High Quality of Recording

Well-considered system characteristics (low level of amplifier noise) and software features (adaptive notch filter, weighted averaging, statistical measures of signal and noise, up-to-date algorithms for automatic response detection) help a device user to obtain a high-quality record quickly. All tests can be performed when patient is awake (non-sedated).

Chirp stimulus

Chirp stimulus is a new stimulus that allows to obtain the response of higher amplitude compared to traditional stimuli. Chirp stimulus takes into account the cochlear anatomy and uses different time shift for different frequencies. Thus, the low frequencies reach the cochlea before the high frequencies. But in the cochlea itself the high-frequency receptors are located before the low-frequency receptors. Due to such stimulus waveform, hair cells’ responses along the whole length of the cochlea (or in one octave range) occur at the same time (synchronized). This leads to the increase of combined neural response that comes to the auditory nerve.

Ultimate Set of Transducers

Neuro-Audio/ABR delivery set includes TDH-39 headphones, the most popular headphones model in the world for ABR testing.

We can optionally supply Ear Tone 3A insert earphones, B-71 bone vibrator (which is applied to estimate air-bone gap to determine type of hearing loss), sound field speakers, TDH-39 acoustically shielded headphones, HDA-280 headphones.

New Standard in Clinical Routine

Modern interface, powerful database, configurable, normative data, high quality of recording and reproducible results allow user to solve a wide range of daily audiological problems with highest accuracy. Many built-in test templates help you to quickly start working with the software, and the flexibility of their customization allows our software to easily suit your needs. Thus, Neuro-Audio/ABR can be used both in clinics and research institutes.
