Advanced Auditory Research
Frequency Following Response (FFR) and Acoustic Change Complex (ACC)
Complete control of stimulus and acquisition timeline
- Define times of acquisition by specifying delays and offsets for each stimulus selected
- Permits mixing of stimuli when Auxiliary Output Channel is installed
- Use simple or complex stimuli, including tones, iChirps, speech, and noise
- Define custom stimuli using the built-in conversion utility
- Use stimulus files up to 8 seconds in duration
- Set stimuli to be presented at a specific time, or to be output continuously
- Combine up to 2 stimuli per ear, or present ipsilateral masking
- Ultra-shielded ER3 and ER2 insert earphones options
Complex ABR Research Module
Acquisition and Analysis of cABR
- Based on Dr. Nina Kraus and colleagues at Northwestern University’s Complex ABR analysis of speech elicited AEP responses
- Includes predefined settings for complex stimuli, including speech syllables BA, GA, DA, and more
- Users can create custom settings and stimuli
- cABR specific label markers
- Includes cABR analysis, spectrogram, and phaseogram tools
- Export data, cross-correlation information, or power spectrum of recording
- Interfaces with MATLAB® modules for further analysis
Available on the Duet and Universal Smart Box
