The physics of sound propagation, attenuation, reflection and scattering is made complex by the development of a complete system of equations that use the following variables:
That's complex and worthy of quiz questions! To circumvent this impediment to understanding and to avoid the difficulty of using, I will "couch" this discussion in the lurid details of animalistic vocal courting.
To learn science quickly or to sell cars, the use of sex seems to work better than equations. You might ask your spouse if this is a truism or a CED quirk. CED, now with a modicum of tradition in the use and abuse of humor in communication, is sure that sexual innuendo helps in the understanding of physics.
