In the middle of the twentieth century, most noise control engineering programs were housed in physics departments; a smaller number were housed in engineering departments -- SuPPLy-SIDE CHALLENgES primarily mechanical and electrical engineering. Today most A major challenge to an adequate supply of well-trained are housed in mechanical engineering departments, although, noise control engineers is that educational programs are as indicated above, many other departments are involved in n ot homogeneous.
