Summary

Students learn the connections between the science of sound waves and engineering design for sound environments. Through three lessons, students come to better understand sound waves, including how they change with distance, travel through different mediums, and are enhanced or mitigated in designed sound environments. They are introduced to audio engineers who use their expert scientific knowledge to manipulate sound for music and film production. They see how the invention of the telephone pioneered communications engineering, leading to today's long-range communication industry and its worldwide impact. Students analyze materials for sound properties suitable for acoustic design, learning about the varied environments created by acoustical engineers. Hands-on activities include modeling the placement of microphones to create a specific musical image, modeling and analyzing a string telephone, and applying what they've learned about sound waves and materials to model a controlled sound room.

Engineering Connection

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.

Sound Environment Shapers

Students are introduced to the sound environment as an important aspect of a room or building. Several examples of acoustical engineering design for varied environments are presented.

Elementary Lesson
Audio Engineers: Sound Weavers

Students are introduced to audio engineers, discovering the type of environment in which they work and exactly what they do on a day-to-day basis. Students come to realize that audio engineers help produce their favorite music and movies.

Musical Images

Students are introduced to the concept of the image of music. After listening to a song, they draw images of it by deciding where different musical instruments were placed during recording. They further investigate audio engineering by modeling the position of microphones over a drum set to create a...
