Step 1. Questions
The next time you are in a quiet room by yourself, clap your hands. Do you hear an echo? If you do, is the echo loud or soft? If not, try clapping a little louder, or speak your name.
In some rooms, like concert halls and auditoriums, sounds project loudly. In other rooms, like libraries lined with books, sounds are absorbed. You may not always notice the difference, but the quality of sound reflections and absorptions affects your experience in a room.
Acoustics is the study of the physical properties of sound. For this e-Journal project, you will research and report on acoustics and its applications. Here are some questions to guide your research:
Are you ready? Begin by visiting the Web sites listed in Step 2. Write down what you learn in the note-taking boxes. You may also use search engines to research acoustics, visit the local library, or interview a musician, engineer, or scientist who studies acoustics.
- How can a room be soundproofed, or built so that sounds do not travel in or out?
- How are concert halls built so that sounds are projected to the audience?
- What are some differences among the sounds produced by different musical instruments?
- What kind of careers involve acoustics?
When you are ready, follow Steps 3 and 4 to write your report.
Step 2. Research
Research answers for the questions you were asked in Step 1. Visit these Web sites. Take notes about them on this page, too!
