Sound comes from vibrations! Adjust frequency and amplitude to see waveforms change in real-time and listen to the actual sound 🔊 Faster vibrations mean higher pitch, bigger ones mean louder sound! Includes a fun target sound matching game. Supports 7 languages.
About this app
Sound and Vibration is an interactive educational web app that demonstrates how sound is created by vibrations. Users can adjust frequency and amplitude sliders to see real-time waveform changes and hear the corresponding synthetic audio pitch and volume. It also features a target sound matching game where learners test their understanding by reproducing specific pitches and volumes to earn stars.
Use cases
- Elementary science students learning about sound waves, frequency, and amplitude
- Teachers looking for an interactive visual and audio tool for physics or music lessons
- Parents introducing basic physical science concepts to kids through hands-on play
Features
- Interactive real-time SVG waveform visualizer driven by frequency and amplitude controls
- Live audio generator button to hear exact pitch and volume changes instantly
- Sound matching game with randomized target prompts, instant feedback, and streak counters
- Dynamic text explaining low and high pitch as well as quiet and loud sound relationships
- Multi-language support for seven languages including English, Korean, Japanese, and European languages
