PHYS-484: Acoustical Measurements



1.  Sound Level Meters  using sound level meters for traffic noise
 The most common "measure" of sound in our human environment is a level in decibels.  However, careful and rigorous measurements of sound use many different kinds of standard metrics, depending on the situation and environment.  In this series of measurements, sound level meters are used in a variety of ways to explore how sound pressure level can be used to understand traffic noise and other sounds in our surroundings, how a sound level meter can be calibrated to incorporate the sensitivity of the human ear, and even how sound waves propagate with distance from a source.
