VIBRATION & SOUND MEASUREMENT
Vibration is monitored using reliable calibrated seismographs during pile
installation, boring activities or blasting. The results obtained are in
the form of peak particle velocity (PPV) with the corresponding frequency.
The PPV obtained is then compared to the allowable emission levels for the
particular structures evaluated.
Sound measurement is obtained in dB(A). Maximum noise levels are measured
at the microphone location and compared to the recommended allowable levels
set by the local authority or the Department of Environment.
Vibration monitoring and Sound measurement ensure seismic and noise levels
are within allowable limits.
