Bio-logic Systems Corp. M·A·S·T·E·R

The M·A·S·T·E·R (Multiple Auditory STEady-State Response) System utilizes innovative technology that facilitates obtaining frequency-specific auditory threshold information, quickly and efficiently. With M·A·S·T·E·R you can obtain a physiologic audiogram to assist with hearing aid fitting when a reliable behavioral audiogram cannot be achieved. Assess up to 4 frequencies per ear simultaneously, tested all at the same time. Rely on state-of-the-art statistical methods of response detection (F-ratio) to assist interpretation with increased accuracy at predicting behavioral audiometric thresholds, even for normal hearing and mild hearing loss. View real-time EEG, the response spectrum and weighted averaged results...ensuring superior data quality. Combine additional audiologic testing functions on the same instrument, Navigator Pro.

Interacoustics ASSR

Interacoustics ASSR - Diagnostic ABR Software Description New Generation ASSR The new ASSR system from Interacoustics is not just another ASSR system. It incorporates years of research aimed at taking ASSR a grand step further: • Up to 50% faster • Full stimulus control • Powerful complete 2 channel system • NOAH compatible (v. 3.6 or later) Reduce Test Time by up to 50% Conventional ASSR systems use an algorithm detection method based in the phase domain or the frequency domain. The Full Spectrum Detection Engine built into the Interacoustics ASSR system combines both methods. It also uses information carried by the higher harmonics of the response to strengthen detection – typically reducing test time with 50%. Full Stimulus Control The Interacoustics ASSR system allows both ears to be tested at the same time. As a test progresses you can control stimulation intensity for each of the 4 simultaneous frequencies in each ear as well as controlling start and stop times for a particular stimulus. Powerful 2 Channel System Using two channels and running two detection engines in parallel allows the Interacoustics ASSR system to also obtain optimum results when used with traditional clinical ABR electrode montage. NOAH Compatible (v. 3.6 or later) If you run the Interacoustics ASSR system under NOAH the resulting Estimated Audiogram will be saved in the NOAH database making the results available for any Hearing Aid Fitting module running under NOAH.
