Abstract
The BioMARK (Biological Marker of Auditory Processing) test, formerly known as BioMAP, is a measure of the frequency following response (FFR) in children to a speech stimulus. The test was designed for 8 to 12 year old children. Other tests of the auditory brainstem such as auditory brainstem responses, have normative values that are valid for listeners from age 2 to adulthood. The goal of the present study was to evaluate the speech-evoked FFR of young adult listeners to determine if a separate set of normative values is needed for this age group. FFR tests using the BioMARK with thirteen listeners aged 18 to 30 years old revealed that a majority of the adults tested fell outside the children-based normative values of the BioMARK. The most consistent differences were found in the amplitude of the FFR responses with the young adults having lower amplitudes than that of the children upon which the normative values of the BioMARK were based. The reason for these amplitude differences in not currently known but the results do support the need to collect normative data for the BioMARK specifically for young adult listeners.
