Virtual Journals Search and Discovery Acoustics Experiment Shows Why It's So Hard to Make Out the Heroine's Words at the Opera Vocal-tract resonances enhance the output of the vocal cords. They also create the distinctions between different vowels sounds. For sopranos singing high notes, the two functions come into conflict. A frustrated listener might well define grand opera as musical theater where you have a hard time making out the words even when they're being sung in your own language. Conceding the point, many opera houses nowadays always flash surtitles above the proscenium. Comprehension is particularly difficult in the higher reaches of the soprano register. Hector Berlioz long ago warned composers not to put crucial words in the soprano's mouth at high notes. A recent study at the University of New South Wales in Sydney, Australia, lays most of the blame on an inescapable tradeoff dictated by the physical acoustics of vowel differentiation and singing very high notes. Acoustical physicists John Smith and Joe Wolfe, working with physics undergraduate Elodie Joliveau, have carried out an experiment that demonstrates why different vowel sounds are almost impossible to distinguish when sopranos are singing in the highest octave of their range. The experimental subjects were eight professional operatic sopranos. Joliveau is herself a soprano, Wolfe is a composer and woodwind player, and Smith plays the double bass. The experimenters used equipment developed by Smith and Wolfe for the analysis of acoustic resonances in musical instruments and in the vocal tract during ordinary speech. The equipment is, in fact, designed to help adults master the sounds, especially the vowels, of a new language. It's also being applied to the correction of speech pathologies.

Virtual Journals Issues and Events Aerobics Acoustics Can Harm Hearing Working out at a gym may improve your muscle tone, but both the staff and exercise participants could damage their ears from the loud music, says physicist Eugenie Mielczarek of George Mason University in Fairfax, Virginia. Over the past three years, Mielczarek measured sound levels in aerobics and other exercise classes at three fitness clubs in Fairfax County. At some clubs, sound levels reached 120 decibels, "close to that of using a jackhammer," she says. Loud music at fitness clubs may destroy your hearing, says physicist Eugenie Mielczarek (above). Regular exposure to loud music slowly destroys the delicate hair cells inside the ear, which reduces the volume and frequency of information transmitted to the brain. Since 1991, the American Council on Exercise (ACE) has published noise level guidelines for its members, but few instructors follow them. The guidelines, based on recommendations by the Occupational Safety and Health Administration, limit noise levels over an eight-hour period to under 85 dBthe equivalent of noise from heavy traffic. But some national fitness club chains hold 45-minute-long classes at 110 dB, says Mielczarek, and most instructors teach six to eight classes each day. "The club staff were either unaware that [ACE] guidelines existed or asked me to leave the class when I asked them to turn the sound down," she adds.

Ph.D. graduates will face competition for basic research jobs. Nature of the Work About this section Back to Top Physicists explore and identify basic principles governing the structure and behavior of matter, the generation and transfer of energy, and the interaction of matter and energy. Some physicists use these principles in theoretical areas, such as the nature of time and the origin of the universe; others apply their physics knowledge to practical areas, such as the development of advanced materials, electronic and optical devices, and medical equipment. Physicists design and perform experiments with lasers, particle accelerators, telescopes, mass spectrometers, and other equipment. Based on observations and analysis, they attempt to discover and explain laws describing the forces of nature, such as gravity, electromagnetism, and nuclear interactions. Physicists also find ways to apply physical laws and theories to problems in nuclear energy, electronics, optics, materials, communications, aerospace technology, and medical instrumentation.

If you are on Windows and are using IE5 or another older browser, then you might try the Java plug-in , which runs faster, but not as fast as the IE6 Java VM from Microsoft; also it has a slower startup time, and won't run some applets that have sound. But you can turn it on and off from your browser configuration. If you are on Windows XP and don't have Java, I would get the Microsoft Java VM instead of Sun's.

Acoustics Demonstrations I. The Missing Fundamental This demonstration explores the relation between the frequency content of a musical note and the pitch perceived by listeners. As we explore in Physics 160, musical notes are complex tones consisting of a fundamental frequency and higher harmonics (known as partials) that are integer multiples of the fundamental frequency. The particular mix of partials is part (but only part!) of what gives different musical instruments their individual character. The pitch of the note is related to the fundamental frequency of the complex tone. However, the pitch of the note remains unchanged even if this fundamental frequency is removed. The accompanying .wav file consists of a complex tone made up of a fundamental and nine higher harmonics. The first tone heard has all the frequencies; the second tone has the fundamental removed but maintains all of the higher harmonics. Each successive tone sequentially removes the lowest harmonic. Notice that although the character of each note changes, the pitch remains the same. Missing Fundamental demonstration II. Circularity in Pitch Judgment

Acoustics Generation, propagation and perception of sound Physiological acoustics. Physical acoustics The theory of sound belongs to Physics as well as to Physiology, because the cause, which under ordinary conditions evokes sound sensations, can be reduced to a strange kind of motion, an investigation of which is indispensable for insight into the nature of sound sensation. Sound sensation arises by stimulation of the auditory nerve. Every stimulation of the auditory nerve causes it; according to Helmholtz , it is in effect "the ear's peculiar mode of reaction to external stimulation". The stimulus, which is to be considered as normal arises through oscillations of an elastic membrane (ear drum), which closes the inner end of the auditory canal. It acts with the aid of the adjacent auditory ossicles and the endolymph (auditory fluid), into which extend the ends of the auditory nerve, on the auditory nerve. This stimulation of the nerve generates the sensation of sound. The ear drum starts to vibrate through the oscillations of the air in the auditory canal, which are caused by the oscillations of the body, which we consider to be the source of a sound . Its oscillations are transmitted to the air in the auditory canal through the air in between them. Corresponding to this process, we must consider the oscillations, arising from the source of the sound and being transferred through the air to the ear, as the source of the sound sensation. In a physical sense, we call this the motion of the sound or, briefly

About Greenville Acoustics The VIOCADEAS research project in the Acoustics Laboratory approaches the analysis of violin quality from a new direction - measuring normal mode properties of the violin. The ultimate aim of VIOCADEAS is to characterize material properties - geometry, elastic moduli, damping and density - of the various substructures to aid in reverse engineering the violin. The automated data acquistion system includes a scanning laser vibrometer in an anechoic chamber with a rotating microphone array to collect vibration and acoustic radiation information simultaneously. CT scans are being used to generate a solid model in the compuer which can then be used for finete element and boundary element analysis, and other simulations. The system will be used to collect a normal mode database over a wide quality range of violins. Bioacoustics The Bioacoustics Research Group has an ongoing project to study sound-producing fish and other marine organisms. Many commercially and recreationally important fish species produce sounds associated with mating behavior. ECU physicists and biologists are working together developing techniques for discriminating species, mapping spawning areas, and counting fish by recording sounds and using spectral analysis techniques. These acoustic techniques are more accurate and faster than the traditional techniques for stock assessment.

Staff 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.
