When teaching sound and related concepts to students with visual impairment, it is important to tie the concepts to real-life. This activity ties the concepts of wavelength, frequency (in Hertz), and pitch together using an on-line hearing test. It should be completed after these concepts have been introduced.
This activity also incorporates technology in a manner that interests the students and is entertaining.
After initial instruction on sound, prepare a student computer by pulling up the following website: http://www.noiseaddicts.com/2010/10/hearing-loss-test/
There are other on-line hearing tests that may be accessed.
Grade 1 – Waves, Light, and Sound
PS4.A: Wave Properties
Sound can make matter vibrate, and vibrating matter can make sound. (1-PS4-1) PS4.B: Electromagnetic Radiation
Grade 4. Waves: Waves and Information
PS4A: Wave Properties: Waves of the same type can differ in amplitude (height of the wave) and wavelength (spacing between wave peaks).
Middle School: Waves and Electromagnetic Information
PS4.A: Wave Properties: A simple wave has a repeating pattern with a specific wavelength, frequency, and amplitude. (MS-PS4-1)
A sound wave needs a medium through which it is transmitted. (MS-PS4-2)
High School: Waves and Electromagnetic Radiation
PS4.A: Wave Properties: The wavelength and frequency of a wave are related to one another by the speed of travel of the wave, which depends on the type of wave and the medium through which it is passing. (HS-PS4-1)
