The goal of this faculty-student research project is a more fundamental understanding of tone production in organ pipes. One instrument that we study is the reed pipe used in pipe organs. Using a recently purchased laser vibrometer, we can measure the velocity at different points on the reed. This is the first experiment that has measured the actual shape of the vibrating reed. The observation of complex vibrational modes, including include torsional and 2nd and 3rd order modes as shown, was completely unexpected. |
| Acoustical Scattering | |
| Primary Investigator: Chuck Niederriter | |
 |
The goal of this acoustical scattering experiment will be to implement a low-coherence reflectometry technique to image through a highly-scattering medium. The impact of scattering coefficient and source coherence length on the system's resolution (the ability to distinguish adjacent objects) and the point spread function (the impulse response of the imaging system) will be investigated. This complete and quantitative investigation will be of great value, and may lead to direct applications in medical imaging or remote sensing in geology. |
