This simulation lets you see sound waves. Adjust the frequency or volume and you can see and hear how the wave changes. Move the listener around and hear what she hears.

Make waves with a dripping faucet, audio speaker, or laser. Add a second source or a pair of slits to create an interference pattern.

A simulation to learn about wave harmonics in a column of air by looking closely at the sound produced by a pan flute.

A free CK-12 account is required to view all materials.

Learn about wave harmonics on a string by looking closely at the sound produced by a violin. Test string tension with harmonic number on violin strings in a simulated practice. Understand sound waves and standing waves in sound.

A free CK-12 account is required to view all materials.

This activity is an investigation where students use tools to determine how the length of a sound source affects its pitch.

This video segment, adapted from ZOOM, explores the different sounds that a simple drinking straw can produce when you cut the straw and blow into it. [1:56]

This video segment, adapted from ZOOM, explores sounds made by homemade drums of different sizes, shapes, and materials. [3:41]

This video segment, adapted from ZOOM, demonstrates how to use a drinking straw and a bottle full of water to make low- and high-pitched sounds. [1:11]

To further their understanding of sound energy, students identify the different pitches and frequencies created by a vibrating ruler and a straw kazoo. They create high- and low-pitch sound waves.

Psychology is designed to meet scope and sequence requirements for the single-semester introduction to psychology course. The book offers a comprehensive treatment of core concepts, grounded in both classic studies and current and emerging research. The text also includes coverage of the DSM-5 in examinations of psychological disorders. Psychology incorporates discussions that reflect the diversity within the discipline, as well as the diversity of cultures and communities across the globe.Senior Contributing AuthorsRose M.

By the end of this section, you will be able to:

Describe the basic anatomy and function of the auditory system
Explain how we encode and perceive pitch
Discuss how we localize sound

Students continue to build a rigorous background in human sensors and their engineering equivalents by learning about electronic touch, light, sound and ultrasonic sensors that measure physical quantities somewhat like eyes, ears and skin. Specifically, they learn about microphones as one example of sound sensors, how sounds differ (intensity, pitch) and the components of sound waves (wavelength, period, frequency, amplitude). Using microphones connected to computers running (free) Audacity® software, student teams experiment with machine-generated sounds and their own voices and observe the resulting sound waves on the screen, helping them to understand that sounds are waves. Students take pre/post quizzes, complete a worksheet and watch two short online videos about "seeing" sound.

This lesson plan engages young students in the study of "sound." The questions What is vibration and what can affect it, thus affecting sound? will be answered during the lab.

A video and a short quiz on electricity, covering static electricity, lightning, and energy generated from electricity. [3:20]

Learn about sound waves with this science experiment. All you need is a balloon!

Discover how the art of DJing in Hip Hop culture and STEM intertwine in collaboration with MacArthur Fellow physicist, Dr. Carl Haber, Bay Area artist Jahi, and Berkeley Lab's own DJ Miles Green. Learn about the physics behind vinyl records and turntables, and the significance of them in the history and culture of Hip Hop. See live demonstrations on the turntables, an exploration on sound and sound restoration, along with various STEM connections to the turntable.

Students examine the existence of sound by listening to and seeing sound waves while conducting a set of simple activities as a class or in pairs at stations. Students describe sound in terms of its pitch, volume and frequency. They use this knowledge to discuss how engineers study sound waves to help people who cannot hear or talk.

This pathway explores the concept of sound. Sound is described in terms of its wave properties, and properties of sound are explained, such as interference, and the Doppler Effect. There is additional information on how hearing works.

Students learn the connections between the science of sound waves and engineering design for sound environments. Through three lessons, students come to better understand sound waves, including how they change with distance, travel through different mediums, and are enhanced or mitigated in designed sound environments. They are introduced to audio engineers who use their expert scientific knowledge to manipulate sound for music and film production. They see how the invention of the telephone pioneered communications engineering, leading to today's long-range communication industry and its worldwide impact. Students analyze materials for sound properties suitable for acoustic design, learning about the varied environments created by acoustical engineers. Hands-on activities include modeling the placement of microphones to create a specific musical image, modeling and analyzing a string telephone, and applyling what they've learned about sound waves and materials to model a controlled sound room.
