 NCE is highly experienced in the measurement and assessment of
shipboard vibration and noise. The company has conducted numerous on-site noise and vibration
tests in many locations around the globe, from the USA to Europe to Asia. NCE has conducted hundreds of noise and
vibration tests on-site ranging from diagnostic surveys on ships with
new or long-term noise and vibration problems to sea trials of new
vessels. Our extensive test experience includes measurements of
airborne noise, vibration testing, underwater radiated noise and sonar
self noise.
Furthermore, our expertise in shipboard noise and vibration allows us
to use this data to not only assess compliance with noise and vibration
criteria but to also determine why excesses may be occurring. This
includes determination of controlling noise sources (gensets, propulsion
engines, propeller, HVAC, or other equipment) as well as noise
transmission paths. Once the source and path have been established, NCE
can work to identify appropriate noise and vibration control measures
that minimize impacts on non-acoustical factors.
 NCE's test equipment includes various two- and four-channel handheld
instruments to multiple 16+ channel data acquisition systems. This
equipment allows NCE to quickly perform ship-wide noise and vibration
surveys, all of which can be performed under multiple operating
conditions. NCE selects the appropriate microphones, accelerometers,
hydrophones, and other equipment necessary for each and every survey.
All of NCE's equipment is highly portable, so measurements can be
performed anywhere in the world, minimizing the costs to the owner or
operator.
