the equations used to describe hearing are more diverse and complex, covering a range of topics such as the physics of sound waves, the anatomy and physiology of the ear, the neural processing of sound in the brain, and the psychoacoustics of perception. these equations may include wave equations, diffusion equations, and statistical models and may be used to describe various aspects of hearing, such as the way in which sound waves are absorbed, reflected, and refracted by different materials and structures, the way in which the ear converts sound waves into electrical signals, and the way in which the brain processes and interprets these signals.
