Acoustic Mirrors

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.

The Anthropology of Sound, Spring 2008
Conditions of Use:
Remix and Share
Rating

This class examines the ways humans experience the realm of sound and how perceptions and technologies of sound emerge from cultural, economic, and historical worlds. In addition to learning about how environmental, linguistic, and musical sounds are construed cross-culturally, students learn about the rise of telephony, architectural acoustics, and sound recording, as well as about the globalized travel of these technologies. Questions of ownership, property, authorship, and copyright in the age of digital file sharing are also addressed. A major concern will be with how the sound/noise boundary has been imagined, created, and modeled across diverse sociocultural and scientific contexts. Auditory examples--sound art, environmental recordings, music--will be provided and invited throughout the term.

A DSP Based Class D Audio Amplifier
Conditions of Use:
No Strings Attached
Rating

Class D amplifiers have proven a higher power efficiency performance against linear classes such as Class A, B and AB. Power losses on Class D amplifiers are mainly due to non-ideality of the output transistors, operating as switches, controlled by Pulse Width Modulators. This example describes a method for utilizing both the Enhanced Pulse Width Modulator (ePWM) and the Analog-to-Digital Converter (ADC) of the TMS320F2808™ digital signal controller as D-Class Audio amplifier. The method involves analog full bridge D-class power amplifier and analog low-pass filtering the amplified PWM signal to remove high frequency components, leaving only the audio-frequency content.
