WIDE RANGE OF FEATURES IN A COMPACT UNIT
Neuro-Audio has a high-quality two-channel amplifier and a built-in auditory simulator with a wide range of intensities and many supported transducers. It is a portable device that has exceptionally high quality of recording. It can record non-sedated ABR easily and does not require a shielded room or audiometric booth!
ABR CLINICAL APPLICATION
— Objective audiometry (hearing threshold search using wave V as the indicator).
— Neurology (identification of pathologies in the VIII cranial nerve and auditory pathways of the brainstem).
— Fitting of a cochlear implant (electrically evoked ABR).
During recording it’s recommended to rely on objective parameters of the response. The residual noise (RN) value helps you determine when to stop averaging. Fmp value indicates presence or absence of a response. Our software calculates these values automatically and shows their reference values. It provides confidence in your results.
The weighted averaging maintains the steadily high record quality even in the condition of a noisy patient (for example, a lot of movements and muscle activity). As a result the waveform morphology is improved and the residual noise is decreased. It allows saving your time and recording non-sedated ABR from young children.
Superimpose ABR waveforms for visual assessment of reproducibility. Just place markers to see the latencies, intervals and amplitudes in analysis tables. Compare results with reference values on the latency/intensity chart. This will improve your efficiency.
The unique adaptive notch filter (and high harmonic filter) together with the “minimize interference” feature (stimulation rate “jitter”) allow recording clear waveforms even with low-quality mains and absence of a shielded room. It saves you time and money.
The Chirp and Chirp-LS stimuli are designed with a cochlea model in mind (frequency rises with time) to maximize the evoked response. That’s why they are optimal for hearing screening and hearing threshold search (wave V is up to twice the size of a click response). Chirp-LS is optimized to be efficient at any stimulus intensity, so it saves your time.
Our software has automatic hearing threshold search protocol. Also you can manually select the list of intensities used during the test which can be modified on the fly. It increases ease of use.
ASSR CLINICAL APPLICATION
Estimation of behavioral audiograms with ASSR. The results of ASSR testing can be used to estimate the behavioral pure-tone audiogram in cases when traditional audiometric testing can’t be performed (for example, in infants and young children).
F-test response detection method accurately and objectively predicts behavioral audiometric thresholds (based on the analysis of the EEG spectrum). The principal component analysis (PCA) method reduces the impact of muscle-induced noises. The fruitful combination of 2-channel recording, Chirp stimulus and weighted averaging allows achieving the most accurate results.
The hearing threshold search is done automatically with a specified step (in dB) and within selected stimulus intensity range. This makes the test significantly easier to perform and saves your time.
You can independently control any of the 8 frequencies in multi-ASSR test. Depending on patient’s state(awake/asleep) you can change the modulation frequency during testing. Also you can change the maximum test duration. Signal (EEG) monitoring is always visible on the screen. All of these allow you to have full control of the test.
The monitoring of residual noise (RN) and response amplitude (A) for each frequency helps answering the question whether to stop the recording or continue it. It gives you confidence in the obtained results and shortens the test time.
Masking (white noise) allows obtaining accurate audiometric thresholds even in patients suffering from unilateral or conductive hearing loss.
