The Sound and Vibration Laboratory uses analytical, numerical, and experimental approaches to create and discover across 11 orders of spatial scale, from 1 nanometer to 100 meters. If it involves sound, vibration, or both, we are interested. We are currently working on $2.8 million in externally funded research, of which approximately $2 million is assigned to a Principal Investigator in our laboratory.
Researchers from biology, computer science, material science, and additive manufacturing collaborate with us on a variety of interdisciplinary projects. We embrace the challenges of working on projects in which sound and vibration is only one aspect. Living and working in the rich academic environment of Boston provides our group with inspiration and perspective derived from diversity, culture, and innovation. Our students travel often to national and international research conferences and frequently receive awards for their presentations.
Our laboratory offers a significant inventory of new equipment for performing experiments. Recent investments in laboratory equipment amount to approximately $0.5 million. This inventory includes a new Brüel and Kjær vibration testing system comprised of shakers, instrumented hammers, accelerometers, microphones, and a data acquisition system. We have procured funding for a 3D vibration imaging system produced by Trillion Quality Systems and will receive that equipment in 2019. Additionally, a number of research groups at Boston University share their laboratory resources with us.
Our laboratory also maintains 3 high-speed boats, each approximately 6 feet in length, capable of autonomous motion and acoustic sensing. Each boat is equipped with an “acoustic brain” that integrates onboard hardware that includes a hydrophone with data acquisition, two GPS, a Raspberry Pi computer, an autopilot, a remote emergency stop system, and a radio antenna.
For high performance computing, we use Boston University's Shared Computing Cluster (SCC) located at the Massachusetts Green High Performance Computing Center (MGHPCC). Over its 20 year history, the laboratory has developed a large collection of documented and benchmarked computer codes related to sound and vibration and these are routinely used for new projects.
We fabricate test fixtures and prototypes at Boston University’s Engineering Product Innovation Center (EPIC), an impressive 15,000 square foot, multi-million dollar makerspace located in the heart of Boston University's Charles River Campus. This includes a 3D metals printer. We also work with the Boston Universtiy’s Scientific Instrument Facility, which is has 10,500 square feet of climate-controlled working area equipped with a Wire Electrical Discharge Machine and a wide array of machining tools.
