The study of architectural acoustics focuses on the rich interplay between sound and interior design. Consider, for example, how an enclosed space will naturally increase sound pressure and raise the frequency. Even though they are usually difficult to calculate, resonance frequencies, also known as eigenfrequencies or natural frequencies, can be easily determined for a perfectly rectangular room with hard smooth walls. The following formula describes the resonance frequencies [f] in a room with a length of L, width of W, and height of H, where the velocity of sound equals c:⏎ f = c/2 [(n/L)^2 + (m/W)^2 + (P/H)^2]^1/2 Hz⏎ Notice that if L, W, and H all equal / will equal 0.⏎ Along with resonance frequencies, the study of sound also takes into account wave acoustics, ray acoustics, diffusion, and steady-state pressure level, as well as sound absorption and transmission through walls. A careful examination of the dynamics involved in sound absorption reveals how incident sound waves are converted to energy. (In the case of porous material, the subsurface lattice of interstices translates sound waves into heat.) Nevertheless, above and beyond the details of frequency shifts and volume fluctuations -- the physics of 'otherness' -- what matters most is a sound's delay.🏁
