INTRODUCTION Acoustics at The University of Texas at Austin began prior to World War II. Immediately after the war, personnel from the Harvard Underwater Sound Laboratory , where sonar and other underwater acoustics technologies were developed during the war, relocated to UT and Pennsylvania State University . The facility at UT is in the Applied Research Laboratories (ARL) and is an internationally recognized center for underwater acoustics. In the 1960s, acoustics research in academic departments at UT gravitated from Physics Department to the Cockrell School of Engineering , where the engineering acoustics program started in and soon extended to Mechanical Engineering Today acoustics in the Cockrell School of Engineering is an interdisciplinary area of teaching and research. It includes basic acoustical wave theory, ultrasonics, underwater sound, transducers, nonlinear acoustics, noise and noise control, and environmental acoustics. The program remains concentrated in Mechanical and Electrical Engineering, but several other departments - mainly Civil Engineering , and Physics - have faculty and students who participate. Major campus facilities include:

Monitoring the global ocean through underwater acoustics Acoustic Monitoring Program: Underwater Acoustics Tutorial The following is a very brief overview of the basic principles of underwater acoustics. The tutorial is presented in twelve topics beginning with "What is Sound?". Choose Topic 1: What is Sound? 2: The Decibel Scale 3: Phase 4: Sound velocity 5: Sound pressure 6: Sound intensity 7: Sound pressure/intensity level 8. Conversion of dB from air to water 9. Source, path receiver model 10. Signal to noise ratio 11. SOFAR channel 12. Frequently used units 1. What is Sound? A propagating sound wave consists of alternating compressions and rarefactions which are detected by a receiver as changes in pressure. Structures in our ears, and also most man-made receptors, are sensitive to these changes in sound pressure (Richardson et al. 1995, Gordon and Moscrop 1996). The basic components of a sound wave are amplitude wavelength , and frequency The amplitude of a sound wave is proportional to the maximum distance a vibrating particle is displaced from rest. Small variations in amplitude produce weak or quiet sounds, while large variations produce strong or loud sounds. The

Highlighted projects Tagged whales ASIAEx 2001 Welcome to the Ocean Acoustics Lab at WHOI Scientists and engineers in the Ocean Acoustics Lab (OAL) at the Woods Hole Oceanographic Institution (WHOI) are conducting research that will lead to a better understanding of the mechanisms of sound propagation in the oceans, and, conversely, how acoustic transmissions themselves can be employed to measure the physical properties of the ocean and its boundaries. Low frequency sound energy is used to probe beneath the sea floor and to measure temperatures and currents in the water column. High frequency energy is used to measure temperature microstructure, small scale currents and wind-blown surface roughness. Many of the tools and techniques for ocean acoustics tomography originated in OAL where they are still the focus of active research. Underwater acousticians in OAL are involved in a wide spectrum of research areas including sonar array performance, acoustic imaging, sound scattering from the Arctic ice and from biologics. OAL scientists and engineers work all over the globe. Recent experiments have been conducted in the frigid Norwegian Sea and the tropical Tasman Sea, in the Gulf of Mexico, the Mediterranean, and the Atlantic and Pacific Oceans.

ACOUSTIC TREATMENT FOR HOME STUDIOS Part 1: Soundproofing Silence is golden, or at least pretty expensive. Commercial recording studios cost hundreds of thousands of dollars to build because they must allow absolutely no sound to enter from a usually noisy urban environment. Double and triple walls, isolated concrete slabs, custom steel doors are all standard but high priced items used in their construction. A studio's sound is its number one asset and most owners will go to any lengths to get it right. Luckily, electronic music does not normally require the extreme isolation needed for recording live ensembles. The use of microphones is infrequent enough that it can be scheduled for predictably quiet times, and close mic techniques, (which are usually appropriate for sampling or vocal lines) don't pick up much noise. Given a reasonably quiet, solidly built house to start with, a decent home studio can be created with modest expense and effort. Some Theory Sound can travel through any medium in fact it passes through solids better than through air. Sound intensity is reduced in the transition from one material to another, as from the air to a wall and back. The amount of reduction (called the transmission loss) is related to the density of the wall as long as it doesn't move in response to the sound. Unfortunately, all walls are somewhat flexible. Any motion caused by sound striking one side of the wall will result in sound radiated by the other side, an effect called coupling. If the sound hits a resonant frequency, the wall will boom like a drum. Most isolation techniques are really ways to reduce coupling and prevent resonances.
