The research is still in the preliminary stages of lab testing. But Guarino hopes to eventually take it into the field to check for bolts that are vibrating loose or degrading through exposure to the elements. "If we're successful, this could lead to implanting permanent, inexpensive accelerometers that could monitor joints continuously," says Guarino.
The talk "Acoustic detection of bolt detorquing in structures" (3a5A8) by Joe Guarino is at 10:30 a.m. on Wednesday, May 20. Abstract: http://asa.aip.org/web2/asa/abstracts/search.may09/asa665.html
5) MUSIC WORDS
In the world of wine tasting, people often use evocative words, such as "fruity" or "chalky," to convert a taste sensation into everyday language. Can one do the same thing for a piece of music? What are the words most used in describing an aural experience? MIT scientist Mihir Sarkar asked more than 800 people to listen to a battery of 64 sounds and then to match them up with a selection of 62 words to describe the quality or timbre of the sounds. Some of the favorite words they chose included "resonant," "metallic," "warm," and "thin." Surprisingly, non-musicians generally chose the same words as musically-trained persons. Sarkar says that one possible application for these studies would be in designing audio post-processing software. For example, a sound engineer could tell the computer, "Make this sound 'brighter'," and that sound track would be made "brighter." (http://web.media.mit.edu/~mihir/projects/sound_design.html).
The talk "The effect of musical experience on describing sounds with everyday words" (4aMU2) is at 9:15 a.m. on Thursday, May 2
