Sound

Lesson 1: Audio Engineers: Sound Weavers: how sound waves change with distance and an introduction to audio engineering and its vital role in music and movie production

Lesson 2: Sound Extenders: how sound travels, and how the telephone invention was the beginning of today's communications engineering

Lesson 3: Sound Environment Shapers: how sound and materials interact, through the exploration of environments designed by acoustical engineers

Many types of engineers must understand the behavior of sound waves to do their work. Audio engineers manipulate sound for the production of music, TV and film. Some engineers design recording studios, microphones and mixing equipment. Acoustical engineers design indoor and outdoor environments that enhance sound or mitigate noise. Communications engineers apply an understanding of sound waves to innovate cutting-edge technology of the global communications industry—everything from cell phones to the Internet.
