Under Water Noise Analyses

  • Noise analysis/Prediction during detailed design stage and Recommendation to be provided.
  • Noise level measurements during sea trials (Approx. 120 compartments) in both Cruising and Max. speed.
  • Machinery vibration measurement around all major equipment (Approx. 70equipments) in both Cruising and Max. speed.
We work according to Applicable Standards:
  • The acoustic levels in ship space should be iaw NES 810.
  • Noise Measurement to be made as per NO 19/07.
  • Equipment Vibration- ISO 10816 or as specified by Navy
Additional Areas:
  • Shock and Vibration Testing
  • Any types of noise and vibration problems in the “design objective” during development
  • Simulations and modeling during design
  • Statistical Energy Analysis/Finite Element Analysis/Fluid Structure interaction analysis
  • Scale model studies
  • Modeling and Testing
  • Development of specialized bulkheads
  • Development of specialized isolation systems
  • Acoustic material design and optimization
