Abstract
One example process includes playing, via one or more loudspeakers, one or more audio frequencies at a particular sound pressure level, measuring, via a sensor, a displacement of a laser beam being emitted from a laser source through a slot of a soundbar housing the one or more loudspeakers during the playing, and determining, via a processor, one or more characteristic coefficients of a grommet based on the displacement.
