Physics of Sound

Explore the Physics of Sound with NI LabVIEW

This lesson uses the Physics of Sound Instrument from the Ergopedia - Essential Physics curriculum. It allows students to visualize live sound using 3 different engineering plots. The waveform graph, the Spectrum plot and the Spectrogram. This instrument is a powerful tool that can enable a new understanding of sound.


As students complete this lesson, they’ll have the opportunity to meet the following learning objectives:
Physics—Students explore and understand concepts of sound, waves, and frequency.
Mathematics – Students explore sine functions, various plots, and Fourier Transforms in a concrete way.
