Acoustics Acoustics is the science of sound. Acoustical scientists help to increase the clarity of music at concert halls, improve hearing aids, and reduce noise from highways and aircraft. Dating back to World War II, federally supported research on long-range underwater communication introduced sonar and ultrasound techniques which have become ubiquitous. Within industrial settings, robots use sonar for positioning themselves and pinpointing objects. Doctors now examine almost every pregnancy in the United States with ultrasound. ACOUSTICS IN THE OCEANS • Ships use sound to "see" other vessels, map the ocean floor, identify mines, and isolate precise spots in which to drill for oil. NOISE CONTROL Another in a series of Physics Success Stories from the MEDICAL ACOUSTICS • Placing electronic "cochlear" implants in the ear of a deaf person restores partial hearing by stimulating the hearing nerve. Acoustics Sonochemistry ConcertHall Acoustics To obtain the best possible audio environment, new concert halls are designed with moveable canopies, curtains, and chambers that can be individually positioned to enhance the unique sound of each presentation.

Home Physics Profile Curriculum ... FEL Degrees Although the curricula are tailored to address Navy requirements, they are developed within the framework of classical academic degrees, meeting the highest academic standards. Each curriculum leads to a master's degree; however, additional study can lead to either an engineer's degree or the doctorate degree. Requirements for the degree Master of Science in Applied Physics are met as a milestone en route to satisfying the Educational Skill Requirements of the curricular program. On a case-by-case basis, some students, depending on background, may earn a Master of Science in Physics, Computer Science, or one of the engineering disciplines. Master of Science in Applied Physics All programs leading to the degree Master of Science in Applied Physics must satisfy the general Postgraduate School's minimum requirements for the Master's degree, must include an acceptable thesis, and must be approved by the Chairman of the Department of Physics. Master of Science in Physics A candidate for the degree Master of Science in Physics must complete satisfactorily a program of study which includes a minimum of 30 quarter hours of physics courses (not including thesis) distributed among courses at the graduate (3000 or 4000) level; of these 30 hours at least 15 hours must be at the 4000 level. Upon approval of the Chairman of the Physics Department, a maximum of 4 hours of courses taken in another department may be applied toward satisfying the above requirements. In lieu of the preceding requirements, students who are qualified to pursue graduate course in physics when they arrive at the Naval Postgraduate School may complete a minimum of 20 hours entirely of 4000 level physics courses.

30. Introduction To Flute Acoustics The physics of airjet instruments. http://www.phys.unsw.edu.au/~jw/fluteacoustics.html

Introduction to flute acoustics This introduction to the physics of the flute requires no mathematics beyond multiplication and division, nor any special acoustics knowledge. For some preliminary information about sounds and vibration, read the introduction to How do woodwind instruments work? Some more technical references are listed near the end of this page. Overview The air jet vibrates The flute as an open pipe Harmonics of an open pipe ... More detailed information To set the mood, listen to Geoffrey Collins play some Debussy. Overview The air jet vibrates The figure at left shows a jet striking an edge and being alternately deflected up and down. The sketch at right represents a cross section of the flute at the embouchure. The flute is an open pipe The flute is open at both ends. It's obvious that it's open at the far end. If you look closely at someone playing a flute, you'll see that, although player's lower lip covers part of the embouchure hole, s/he leaves a large part of the hole open to the atmosphere, as shown in the sketch above. Let's begin by considering a pipe that is simpler than a flute. First, we shall pretend that it is a simple cylindrical pipe-in other words we shall assume that all holes are closed (down to a certain point, at least), that the head is cylindrical, and we shall replace the side mounted embouchure hole with a hole at the end. In fact, this is more like a shakuhachi than a flute. It's a crude approximation, but it preserves much of the essential physics, and it's easier to discuss. (We shall introduce the effects of finger holes and the embouchure geometry below, or you can consult our

Jamie Whitten National Center for Physical Acoustics S ince its inception in 1986, the Jamie Whitten National Center for Physical Acoustics (NCPA) has evolved into the premier university based physical acoustics research center in this country. Staffed with some of the best known scientists and engineers in the world, NCPA engages in sponsored research programs supported through federal agencies, private industries and small businesses. N CPA programs run the gamut of research from basic studies into the nature of sound and its interaction with solids, liquids and gases to the development of prototype systems through applied studies. O ur greatest products are future researchers, teachers, practitioners, and leaders in acoustics. NCPA scientists direct students in laboratory and field research. NCPA is committed to educating students in the frontiers of the physics of acoustics. I n acknowledgement of NCPA's excellence in acoustics research, the following in-house organizations were established: the Institute for Humanitarian Demining, the Army Center of Excellence in Acoustics, and the FAA Center of Excellence in Source Noise Reduction. University of Mississippi Lyceum NCPA resides on the campus of the University of Misssippi , which, in turn is located in the beautiful and charming town of Oxford, Mississippi

NCPA: Ultrasonics Research group The National Center for Physical Acoustics, located on the University of Mississippi at Oxford Campus, is one of the nations premiere acoustics research institutions. In the Ultrasonics Research Group, we use mechanical (acoustical) waves at frequencies between 20 kilohertz and 100 Megahertz to study the underlying properties of physical systems. A variety of ultrasonic techniques are applied to the study of both liquids and solids (both crystalline and amorphous). Our research efforts are concerned with both fundamental and applied physics.

Various branches of acoustics that deal with different aspects of sound and hearing include bioacoustics, physical acoustics, ultrasonics , and architectural acoustics. Unlike electromagnetic radiation , which can travel in the vacuum of free space, sound Waves require a medium (solid, liquid, or gas) in which to travel. Another important difference is that sound travels much slower than electromagnetic radiation; the speed of sound in air at sea level is approximately 1000 ft/sec (300 m/sec), which is roughly a millionth the speed of light in air. Sound waves are longitudinal, which means that the material particles transmitting the waves oscillate in the direction of propagation. Important factors to be considered in working with sound include reverberation and interference . Reverberation is the persistence of sound in an enclosed space caused by repeated reflections. Reflection of sound sometimes causes an echo . Depending on the location of the listener and the frequency of the sound, varying degrees of interference between the primary sound and its reflections will be produced. Reflection can be reduced by the use of sound-absorbent materials, which are usually soft and porous, such as draperies, upholstery, carpets, acoustic tile, or plaster. In a room, reflection is decreased by the presence of people and open windows and doors.
