Frequency: the number of cycles of vibration completed in 1 second: measured in hz can be analogous to pitch even though other factors affect pitch, phase: the starting position of the pendulum or mass. ***natural resonant frequency or fundamental frequency: is the natural frequency or speed of vibrations from a given object. Inverse square law: the dependence of sound pressure and intensity on distance (more distance, lower intensity and pressure) ***only works on free eld environments. Free field: type of environment in which the wave is not re ected from surrounding surfaces: diffuse field: sound is re ected from many surfaces.
