Use sound recording and analysis software to record voices of your family members. Can you figure out ways to identify each family member by just looking at the analyzed sound patterns from their voice (e.g., spectral frequency analysis)? Develop a hypothesis about what types of sound analysis will identify an individual. Have a helper record additional test files of your family members, without telling you which file belongs to whom. Unplug your computer speakers and see if you can… Read more

Learn how to edit sound files so that you can manipulate the recorded sound mathematically. You can either find specialized audio editing software or do background research to teach yourself about sound file structure so that you can write your own simple program to manipulate sound files. Try arithmetic operations on the sound values (e.g., adding or subtracting a constant, multiplying or dividing by a constant). How do these operations alter the sound? Try other mathematical operations:… Read more

A concert piano. It's a beautiful instrument and a spectacular sight when it's all set up on stage. The first thing you may notice when you first look at a concert piano is the impressive-looking soundboard, that large board on the back of the piano that is tilted up at an angle. It is used for amplification. The sound board greatly increases the volume of sound coming from vibrations of the strings. The soundboard is positioned so that it gathers the sound vibrations coming from the strings… Read more

What are the best materials to use for blocking out unwanted noise from the environment? You can build a test box (or test frame) around an audio speaker. Use a sound level meter to measure the speaker output. Use different materials to cover the walls of your test box (or frame), and see which materials do the best job at blocking the sound. For a more advanced project, perform your tests using different sound frequencies. Are some materials better at blocking certain frequencies than… Read more

Did you know that waves travel through the Earth's crust all the time? One major source of these waves is earthquakes, although ground motion can also be caused by something man-made, such as a mine blast or nuclear explosion, or other natural events, such as landslides or volcanic activity. How does an earthquake cause these waves? The entire outer shell of the Earth, known as the lithosphere, is made up of tectonic plates that are constantly moving. There are seven or eight large… Read more

Beats are a pattern of oscillating sound intensity (i.e., the volume of the pattern grows and fades with a regular cycle). They occur when two tones of almost equal frequency interfere. People can perceive beat frequencies below about 7 Hz. Figure out how to create sound files to play pure tones on your computer. Create files with a pure tone of one frequency in the left channel, and a pure tone of a different frequency in the right channel. Systematically explore different frequency… Read more

Can you remember what the weather was like last week? Last year? Here's a project that looks at what the weather was like for over a hundred years. You'll use historical climate data to look at moisture conditions in regions across the continental U.S. You'll use a spreadsheet program to calculate the frequency of different moisture conditions for each region and make graphs for comparison. Which part of the country has the most frequent droughts? The most frequent periods of prolonged… Read more
