Acoustic Particle Setup

Caption

Photograph of the experimental setup, which consists of a 2-meter-long acrylic tube with funnels at both ends to direct the sound from a computer speaker (bottom left) out to absorbing media (top right). A web camera is set above the setup to track the motion of the particles, and a microphone is inserted into the output funnel to measure the transmission spectrum in time.
