Noise & Vibration Measurement

SOUND MONITORING

 

Sound monitoring records and evaluates environmental noise levels (dB) generated by site activities. It ensures compliance with Department of Environment (DOE) Malaysia guidelines and protects sensitive areas from excessive noise.

 

Measure Parameters:

  • LAeq (Equivalent Continuous Noise Level)
  • Lmax / Lmin (Maximum / Minimum Noise Levels)
  • L10 and L90 (Statistical Noise Indicators)

 

Standards & References

  • DOE Malaysia 2-19 (Planning Guidelines for Environmental Noise Limits and Control

 

 

VIBRATION MONITORING

 

Vibration Monitoring measures and evaluates ground and structural vibrations generated by pile driving, blasting, or heavy equipment operation.

Using dual-axis or tri-axial accelerometers, the system continuously records Peak Particle Velocity (PPV) and Frequency to assess both ground motion and building response to vibration.

 

Purpose:

  • Monitor and control vibration levels during construction activities
  • Assess structural response to ground vibrations
  • Ensure compliance with environmental and structural vibration limits
  • Protect adjacent buildings, utilities, and sensitive installations

 

Standard & Compliance:

  • Department of Environment Malaysia 2021 (Planning Guidelines for Vibration Limit and Control in the Environment
  • BS 7385-2:1993 (Guide values for cosmetic damage: continuous and intermittent vibration limits)
  • DIN 4150-3 (Foundation vibration limiting values for cosmetic damage)

 

Key Benefits:

  • Continuous real-time vibration and frequency monitoring
  • Evaluates building response and potential cosmetic damage risk
  • Ensures compliance with international and local vibration standards
  • Provides alert-based control and comprehensive reporting
