Analysis of Characteristics of Noise for Construction trial in 3.5 MW Fish Ship

Key Points

• The aim is to analyze noise characteristics during the construction of a 3.5 MW fish ship and evaluate compliance with sound standards.
• Conducted acoustic measurements near engine rooms and classrooms
• Applied floating structure layers for noise reduction
• Compared noise levels across different compartments
• Classroom noise recorded at 59.2 dB(A), close to the threshold of 60 dB(A)
• Main engine noise measured at 101.5 dB(A), meeting the 110 dB(A) standard
• Noise in the main engine control room at 66.6 dB(A), adhering to the 67 dB(A) limit
• Auxiliary machinery room noise exceeded standards at 109.5 dB(Cpeak) and 123.3 dB(Cpeak)
