A theory of sounds owes much to accounts of sound-related phenomena and their perception. This chapter presents a unified account of transmission through barriers, destructive and constructive interference, and Doppler effects. Rather than effects that pertain to sounds, these cases should be understood primarily as wave-related phenomena that produce illusory auditory experiences. The illusions stem from the way that waves transmit information about sounds. This unified account has advantages in explaining auditory experience and perceptual constancies.
