◇ Spectrum analysis function: Do spectrum analysis of stimulus and evoked results separately
◇ Stimulus and latency curves: distinguishing sensorineural hearing loss from conductive hearing loss
◇ Can be combined with Otoacoustic SmartOAE
The latest scientific research achievement: cABR
The frequency of brain waves induced by speech sounds has the characteristic of reproducing / following the frequency of stimulation sounds (FFR), and the implementation method is the same as the recording method of ABR. Utilizing this fidelity characteristic of nerve conduction, in the form of ABR examination, the subject's auditory center's ability to recognize speech was evaluated, which improved the audiological examination by a level (as shown on the right), showing a very broad Application prospects:
1) Newborn speech function screening;
2) Impaired auditory processing;
3) Ability to understand speech in a noisy environment. Such as: hearing aid fitting evaluation;
4) Prediction of the effect of speech training after cochlear implantation.
