SPL Employment SIGNAL PHYSICS LABORATORY (SPL) The Signal Physics Laboratory conducts advanced research in a broad range of topics focused primarily on acoustics . Historically, our work has focused on underwater acoustics, primarily for the U.S. Navy ; more recently our sponsor base in underwater acoustics has expanded to include U.S. government law enforcement and intelligence agencies . We currently have ongoing research in the areas of active and passive sonar and submarine vulnerability reduction . These efforts involve a combination of basic research, algorithm development, system prototyping/validation, and full-scale data acquisition and measurement systems. SPL specializes in signal and information processing based on an understanding of the physics of signals and noise including their generation, propagation, and reception

Go to the Woodruff School's Graduate Program/Admissions Page Introduction The School of Mechanical Engineering at Georgia Tech offers graduate programs in Acoustics and Dynamics at the master's and Ph.D. levels. Research in Vibration falls within these categories, as well. The Acoustics and Dynamics research group within the Mechanical Engineering Program includes 5 faculty members who have a primary interest in Acoustics and Dynamics. Interaction among the various members of the group has resulted in an interleaving of collaborative research efforts. An attractive feature of the Graduate Program in Mechanical Engineering is that students may, if they desire, directly enroll in the Ph.D. program without first obtaining a master's degree. The Acoustics and Dynamics research group also maintains ties with several faculty members that are involved in this research area in other schools within the Institute. These other units are Electrical Engineering, Aerospace Engineering, Mathematics, and Architecture, as well as the Georgia Tech Research Institute.

At present the principal focus of interest is in the behaviour of wind instruments. Although the basic physics of these instruments has been understood for more than a century, many aspects of great musical importance are not yet adequately explained. Our approach to this problem involves a set of interlinked experimental and theoretical studies. In the Department's anechoic chamber, lined with foam rubber wedges to create an environment almost totally free from reflected sound, apparatus has been developed to investigate in detail the interior shape and the resonance characteristics of a wind instrument.

advanced search Subscribe to Physics News Update Physics News Graphics Physics News Links Archives Number 565 November 14, 2001 by Phil Schewe, James Riordon, and Ben Stein Quantum Acoustics The flatland world of electrons residing at the two-dimensional interface between semiconductor planes is an integral part of quantum-well lasers found in many popular electro-optical devices such as grocery scanners and CD players. But the physics at work in these two dimensional electron gases (2DEG) is far from exhausted. Two years ago a team of physicists used subtle sound waves (surface acoustic waves, or SAW) rippling through one of the semiconductor planes used to confine the electrons to form up the electrons into orderly lines (in effect "quantum wires") and also to transport controllably these formations (see Physical Review Focus Now the team, consisting of physicists at the Institute of Semiconductor Physics in Novosibirsk, Russia (contact Sasha Govorov, temporarily at Ohio University, govorov@helios.ohiou.edu) and the Ludwig Maximilans University in Munich (Achim Wixforth, achim.wixforth@physik.uni-muenchen.de ), propose to use two such surface acoustic waves, oriented at right angles, to confine the electrons to essentially zero-dimensional pockets which can be maneuvered around. Thus initially free electrons are organized into quantum wires and dots by intense sound waves.

Physics Tutorial Sound Waves and Music Lesson 1 Sound is a Mechanical Wave ... Lesson 5 Lesson 1: The Nature of a Sound Wave Sound is a Mechanical Wave Sound and music are parts of our everyday sensory experience. Just as humans have eyes for the detection of light and color, so we are equipped with ears for the detection of sound.We seldom take the time to ponder the characteristics and behaviors of sound and the mechanisms by which sounds are produced, propagated, and detected. The basis for an understanding of sound, music and hearing is the physics of waves. Sound is a wave which is created by vibrating objects and propagated through a medium from one location to another. In this unit, we will investigate the nature, properties and behaviors of sound waves and apply basic wave principles towards an understanding of music.

The Definition of Sound The first thing we should understand about sound is that it is a mechanical wave. Any mechanical wave is a disturbance that travels through some material or substance, such as air, called a medium for the wave. Sound waves can travel through any kind of gas, liquid or solid medium.
