Engineering Solutions to Noise and Vibration Problems

Jesse Spence

Mr. Spence is the Director of Technology at Noise Control Engineering, LLC. He joined the company in 2001. Mr. Spence has been the principle investigator and project manager on many projects of varying scope, requiring airborne noise, vibration, underwater noise, dynamic stress, and other specialized predictions and measurements. Mr. Spence has developed acoustic solutions for many vessel types including Platform Supply Vessels, Offshore Patrol Vessels, large and small Military Vessels, Research Vessels, Dredgers, Drillships, Drilling and Production Platforms, and other commercial vessels.

Mr. Spence is the product manager for NCE's Designer-NOISE® prediction software, responsible for coordinating programming updates, ensuring product quality, and interfacing with customers. Mr. Spence is the lead engineer/consultant on many projects when Finite Element Analysis is required to predict the vibration response of vessel and offshore structures, ranging from machinery foundations and masts to entire vessels. Mr. Spence recently led an effort performed by NCE for the Ship Structures Committee to identify appropriate methods of modeling low frequency ship vibrations using finite element methods.

Mr. Spence has been one of the lead developers of NCE's Buoy Acoustic Measurement System (BAMS) which allows for accurate measurements of underwater noise from vessels and other marine activities to be performed worldwide for reduced cost relative to other methods. Mr. Spence has also developed custom measurement and analysis tools for use both in-house and by third-party customers. Mr. Spence has been involved in specialized projects including development of underwater noise barriers, high frequency vibration testing (2 kHz to 60 kHz) of an underwater transducer array, testing and development of new absorption/cladding materials, quieting specialized underwater equipment, and detailed investigations of methods of treating bow thruster induced noise and vibration on support vessels. Mr. Spence was also the principle investigator for a year-long study into methods of reducing underwater sound from all oil and gas industry activities including seismic exploration, pile driving, explosives, vessels, platforms, and other operations.

Prior to his work at NCE, Mr. Spence was a Senior Transducer Engineer at Boston Acoustics where he was responsible for the design and manufacture of new transducers for high-end audio applications. He holds a BSME from the University of Rochester and a MS in Acoustics from Boston University. He is a member of Institute of Noise Control Engineers (INCE) and the Acoustic Society of America (ASA).
