Frequency specific measurement of hearing thresholds The objective determination of frequency specific hearing thresholds gains increasing importance within auditory evoked potentials measurements. It is crucial to know the exact threshold curve for hearing aid fitting purposes as well as for cochlear implantation decisions. Nowadays, different methods are available. Chirp-ABR The Chirp-Stimulus generates an optimized synchronous excitation of neurons in all regions of the basilar membrane. The stimulus structure also allows modifications to excite predefined regions in the Cochlea. The...

Corona – free configurable ABR-System The measurement of Acoustic Brain Responses (ABR) is a basic diagnostic tool in the daily audiologic routine. ABR can be used to detect disorders from the peripheral hearing organ to the neural pathway. Stimulus rate, stimulus polarity, analysis time and other parameters can be selected. Measurement sequences can be stored and re-used for other measurements. Especially to meet these demanding applications in clinics and private practices the ABR device "Corona" was been developed. One or two channel versions are offered to match different requirements....
