What I’m Listening to Now

“I enjoy the large variety of interesting projects that we get involved with here at Acentech, especially the “detective work” aspect of figuring out the sources of noise and vibration. I joined Acentech as part of the merger with RH Lyon Corp in 2005, and Dick Lyon (my former thesis advisor at MIT and a luminary in this field), has been an inspiration to me throughout my career.”

David Bowen is a principal consultant and director of Acentech’s Noise and Vibration group. With more than 30 years of experience, David performs sound and vibration analyses associated with solving product noise and other probelms. His work includes sound quality evaluations and source/path identification efforts that lead to effective modifications, as well as studies for developing, implementing and evaluating various signal processing procedures for use in remote sensing, active noise/vibration control, and machinery diagnostics.

In addition to his consulting work, David has served as project lead on many government-sponsored programs. Examples include the use of vibration and electrical signals for remote condition monitoring of machinery, the use of acoustical signals for remote reconstruction of cave and tunnel geometry, and the use of vibration signals acquired on building exteriors to locate and identify machinery that may be operating within. Other representative projects include the development of loudspeakers and other transducers, the design of effective audio signal processing to change the perceived height of sounds in home theater applications, and noise reduction of products ranging from medical devices to appliances to truck-mounted refrigeration units.

Pet peeves?

I am a member of many professional societies, but since one of my biggest pet peeves is the unnecessary use of acronyms, I won’t give you the alphabet soup of them.

In a previous life, I raced motocross. Working on those motorcycles no doubt influenced my decision to major in mechanical engineering. Today, I spend much of my spare time maintaining our 130+ year-old house in Cambridge.
