Sound Wave Visualizer & Original Composition

Grades 6-850-60 minSource: Creative Dad Company

Students use a free audio tool to see the waveforms of different sounds. Then they compose a short original piece that plays with pitch and loudness.

Quick Start

Digital downloads only.

$0 to buy. Printing noted separately.

Student time: one class period, one day.

Teacher prep / build-ahead: separate from student time.

Scale it

The default plan is one class period on a single day.

Scale back: Fit it into a shorter period, use fewer effects, or run a demo instead of a build.

Scale up: Add one extra effect, or spread the share-out across another day.

Steps

  1. Record three short clips: a low note, a high note, and a sharp percussive hit.
  2. Load each clip into a free waveform viewer and measure frequency (count cycles in 0.01 seconds and multiply by 100, or use the spectrum tool) and amplitude (peak height). Calculate wavelength as 343 m/s divided by frequency. Record values in a data table.
  3. Draw a scaled wave diagram for each clip that shows wavelength spacing and amplitude height using your numbers.
  4. Amplitude and energy test: record the same note at 4 volume levels. For each, measure peak amplitude in the waveform viewer and the loudness in decibels with a free sound meter app held at the same distance. Record a table.
  5. Graph loudness (a measure of the energy reaching the ear) versus amplitude. Describe the pattern, calculate how many times bigger the loudest amplitude is than the softest, and note that frequency stayed the same, so the change in energy came from amplitude.
  6. Compose a 30-second piece that changes pitch and volume on purpose, and label the frequency, amplitude, and predicted loudness (read from your graph) at three key moments.
  7. Present the piece with the waveform, the data tables, the loudness versus amplitude graph, and your amplitude and energy explanation.
