Sound pressure waveforms from the DCC prototype and its winding block. In both cases, the microphone was centered 25 cm from the closest head-facing surface (insets). The start of the TMS pulses is at −0.73 ms to compensate for the sound propagation delay in the air. The exposed winding block (101 dB(Z) peak) is compared to the complete coil with outer casing (79 dB(Z) peak). Both configurations are measured for stimulation strength of 167% RMT; thus, the complete coil had 18% higher current to compensate for the thickness of the casing.
