Audible sound can easily be detected using a microphone and sampled through a PowerLab to LabChart. There are wide range of applications where recorded sound might provide utility in research.
A cardio microphone can be used to detect the timing of valve closures in the heart, or a sound may be played to a subject and simultaneously sampled in order to elicit and detect an emotional response. LabChart’s Audio Output feature can make use of this signal for qualitative investigation post analysis.
