This unit launches with a slow-motion video of a speaker as it plays music. In the previous unit, students developed a model of sound. This unit allows students to investigate the cause of a speaker’s vibration in addition to the effect.

Students dissect speakers to explore the inner workings, and engineer homemade cup speakers to manipulate the parts of the speaker. They identify that most speakers have the same parts–a magnet, a coil of wire, and a membrane. Students investigate each of these parts to figure out how they work together in the speaker system. Along the way, students manipulate the components (e.g. changing the strength of the magnet, number of coils, direction of current) to see how this technology can be modified and applied to a variety of contexts, like MagLev trains, junkyard magnets, and electric motors.

Students play and record the “Mary Had a Little Lamb” song using musical instruments and analyze the intensity of the sound using free audio editing and recording software. Then they use hollow Styrofoam half-spheres as acoustic mirrors (devices that reflect and focus sound), determine the radius of curvature of the mirror and calculate its focal length. Students place a microphone at the acoustic mirror focal point, re-record their songs, and compare the sound intensity on plot spectrums generated from their recordings both with and without the acoustic mirrors. A worksheet and KWL chart are provided.

Acoustics (from Greek ακουστικός pronounced akoustikos meaning "of or for hearing, ready to hear") is the science that studies sound, in particular its production, transmission, and effects. The science of acoustics has many applications which are dependent upon the nature of the sound that is to be produced, transmitted or controlled.

The Acoustics of Speech and Hearing is an H-Level graduate course that reviews the physical processes involved in the production, propagation and reception of human speech. Particular attention is paid to how the acoustics and mechanics of the speech and auditory system define what sounds we are capable of producing and what sounds we can sense. Areas of discussion include:

the acoustic cues used in determining the direction of a sound source,

the acoustic and mechanical mechanisms involved in speech production and

the acoustic and mechanical mechanism used to transduce and analyze sounds in the ear.

In this lesson, students are introduced to audio engineers. They discover in what type of an environment audio engineers work and exactly what they do on a day-to-day basis. Students come to realize that audio engineers help produce their favorite music and movies.

This module is part of the Audio Production 1 class offered at Lane Community College in Eugene, OR. The purpose of this class is to introduce students to sound manipulation for time-based media. The class covers three elements; field recording, foley capture and ADR. The course uses Pro Tools for recording, editing, mixing and mastering.This first module looks at mobile recorders. It is broken up into three tasks.Activity 1: Getting to know the equipmentActivity 2: Using the equipmentActivity 3: Importing and Editing sounds captured.The mobile recording units used at LCC are the PMD-660, Zoom H4n (and Pro) and Tascam DR-110. You will need the following equipment:mobile recording devicesXLR mic cablesshotgun microphones------------------------------------------Footnote:Image used: Two individuals recording ecoacoustics in the field. Recording ecoacoustics in rural Illinois, USAPublic DomainFile:Ecoacoustics recording in Rural Illinois, USA.jpgCreated: 04:24, 11 November 2009 (UTC) July 2009

When you spin it around, this toy sounds like a swarm of buzzing bees.

Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

By the end of this section, you will be able to:Describe the relationship of amplitude and frequency of a sound wave to attributes of soundTrace the path of sound through the auditory system to the site of transduction of soundIdentify the structures of the vestibular system that respond to gravity

Students wire up their own digital trumpets using a MaKey MaKey. They learn the basics of wiring a breadboard and use the digital trumpets to count in the binary number system. Teams are challenged to play songs using the binary system and their trumpets, and then present them in a class concert.

Using different texts students learn many ways to communicate with sound. With this lesson, students will learn also how to communicate with sound over a distance.

This class explores sound and what can be done with it. Sources are recorded from students’ surroundings - sampled and electronically generated (both analog and digital). Assignments include composing with the sampled sounds, feedback, and noise, using digital signal processing (DSP), convolution, algorithms, and simple mixing. The class focuses on sonic and compositional aspects rather than technology, math, or acoustics, though these are examined in varying detail. Students complete weekly composition and listening assignments; material for the latter is drawn from sound art, experimental electronica, conventional and non-conventional classical electronic works, popular music, and previous students’ compositions.

Students gain a deeper understanding of how sound sensors work through a hands-on design challenge involving LEGO MINDSTORMS(TM) NXT taskbots and sound sensors. Student groups each program a robot computer to use to the sound of hand claps to control the robot's movement. They learn programming skills and logic design in parallel. They experience how robots can take sensor input and use it to make decisions to move and turn, similar to the human sense of hearing. A PowerPoint® presentation and pre/post quizzes are provided.

In this lesson, students learn that sound is energy and has the ability to do work. Students discover that sound is produced by a vibration and they observe soundwaves and how they travel through mediums. They understand that sound can be absorbed, reflected or transmitted. Through associated activities, videos and a PowerPoint presentation led by the teacher, students further their exploration of sound through discussions in order to build background knowledge.

Students are presented with the following challenge: their new school is under construction and the architect accidentally put the music room next to the library. Students need to design a room that will absorb the most amount of sound so that the music does not disturb the library. Students use a box as a proxy for the room need to create a design that will decrease the sound that is coming from the outside of the box. To evaluate this challenge, students use a speaker within the box and a decibel meter outside the box to measure the effectiveness of their design.

Students begin by following instructions to connect a Sunfounder Ultrasonic Sensor and an Arduino Microcontroller. Once they have them set up, students calibrate the sensor and practice using it. Students are then given an engineering design problem: to build a product that will use the ultrasonic sensors for a purpose that they all specify. Students will have to work together to design and test their product, and ultimately present it to their classmates.

This six-day lesson provides students with an introduction to the importance of energy in their lives and the need to consider how and why we consume the energy we do. The lesson includes activities to engage students in general energy issues, including playing an award-winning Energy Choices board game, and an optional graphing activity that provides experience with MS Excel graphing and perspectives on how we use energy and how much energy we use.

Drawing on the author's four decades of experience as a concert oboist, this open access book studies a number of foundational issues in the philosophy of music, such as musical meaning and expression, musical ontology and the existence of the musical work, the relation between music and language, and the phenomenology of music. The book surveys the development of Western classical music from the Baroque era through to the 20th century, both from the perspective of contemporary Lithuanian philosophers such as Girnius, Maceina, Šliogeris, and Jackūnas, and 20th century European philosophy. In addition to discussing key questions in the philosophy of music, the book also analyses technical musical terms such as articulation, phrasing, and rhythm.
