Abstract
A system and method of central auditory processing testing and evaluation provides for identifying clinically relevant neural synchrony in the auditory brainstem pathway. The system or method finds use as a tool to evaluate auditory processing disorders, and hence, potential auditory system and/or learning disabilities. The system or method may further find use in the selection and fitting of hearing corrective appliances such as hearing aid or cochlear implant devices and/or in the selection and implementation of auditory training regimens.
Claims20
A method of evaluating auditory processing in the assessment of a language-based learning impairment comprising:
- presenting a set of auditory stimuli, the set of auditory stimuli comprising a plurality of discrete auditory events;
- measuring a brainstem response to the set of auditory stimuli;
- recording an average waveform;
- wherein the average waveform represents the brainstem response to each of the plurality of discrete auditory events, the average waveform including a plurality of peaks;
- selecting at least one of the plurality of peaks;
- determining with a computing device characterizing information regarding the at least one of the plurality of peaks;
- calculating a composite score;
- and evaluating a language-based learning impairment based on the composite score.
