Surfing on Sound Waves

Learn all about sound and sound waves in this SOCK as a part of the International Year of Sound (2020-2021), in partnership with the Acoustical Society of America (ASA)!

Portable Oscilloscope and Microphone: Sound is not visible to the human eye, but have you ever wondered what sound looks like? This demonstration utilizes a portable oscilloscope to visualize sound signals! https://www.spsnational.org/programs/outreach/portable-oscilloscope-and-microphone

Longitudinal and Transverse Waves: What are waves? And, more specifically, what are sound waves? A slinky is used to explain two types of waveforms - longitudinal and transverse - while a tuning fork exhibits sound waves as longitudinal waves. https://www.spsnational.org/programs/outreach/longitudinal-and-transverse-waves

Interactive Soundscapes: We can see many features of a place, but what we hear in a place tells us a lot more than what we see. Here we will listen to soundscapes and travel to different places via sound. https://www.spsnational.org/programs/outreach/interactive-soundscapes 

Doppler Ball: What exactly is the doppler effect? To find out,use a foam ball with a buzzer to throw around and experience the doppler effect! https://www.spsnational.org/programs/outreach/doppler-ball 

Elastic Cord: What are standing waves? What is a fourier transform? Use a latex rope to demonstrate different modes of standing waves and to construct waves! https://www.spsnational.org/programs/outreach/elastic-wave 

Vocal Fold Straws: Where does our voice come from? Learn about how our vocal folds work by using straws to create vibrations! https://www.spsnational.org/programs/outreach/vocal-fold-straws
