NCE has developed two software programs that are used in the shipbuilding/marine industries. A
brief description is given below and detailed description is given on the link below.
 Designer-NOISE: This GUI-enabled software is used for
shipboard compartment
noise predictions. A model made-up of structural elements is constructed with compartments and
major machinery (noise sources). Information about the structure (bulkhead thickness, stiffeners),
joiner panels, and acoustic insulation is entered into the model. Both sound and vibration levels
of the major machinery need also be entered into the program. Designer-NOISE then calculates the
octave bands and overall A-weighted sound pressure levels. Noise treatments can be added into the
model to determine how to treat a vessel to minimize noise. Use the link to see more details or
contact Jesse Spence at jesse@noise-control.com.
 Sound-Guard: This program is for monitoring underwater
radiated noise (or self-noise) from a ship. It was originally designed for the University of
Delaware's quiet
research vessel, R/V HUGH R. SHARP which was designed to meet the ICES CRR 209 underwater
noise
limits. It accepts inputs from either hull mounted hydrophones or accelerometers and displays the
sound levels in 1/3 octave bands on the screen. The system was designed to operate with a
touch-screen and is very easy to operate. Use the link to see more details or contact Nathan Jones
at nathan@noise-control.com.
