Magnetoencephalography with optically pumped magnetometers is rapidly evolving both for full head coverage applications and for low sensor count applications. Here a three dual-axis OPM setup is introduced to measure auditory brain responses. Without specific anatomical knowledge about the participant an auditory M100 response was detected with three sensors over the left temporal lobe for a sound delivered into the contralateral right ear. An accelerometer was used to investigate the effect of unavoidable participant movements on the resulting average signals.
