Audible acoustic noise generated by multilayer ceramic chip (MLCC) capacitors on printed circuit boards (PCBs) creates an undesirable phenomenon in consumer electronics. When a changing voltage is applied to MLCC capacitors, the internal ceramic material expands and contracts due to piezoelectric and electrostrictive effects causing the PCB to vibrate at audible frequencies. The Project A Cappella clinic team has characterized how placement and electrical stimulus affect the magnitude of the acoustic noise to inform future PCB design choices.
