There are numerous sources of noise and vibration in any construction project, from small hand tools, to large machinery such as drills, pile drivers, excavators and lorries. There are different types of regulations, both national and local, which establish maximum authorised levels to ensure that such noise and vibration does not harm the environment.
Noise and vibration are two closely related phenomena. Both are the result of an oscillation with a certain frequency. The essential difference lies in the medium through which they propagate.
A high level of prolonged exposure to vibrations triggers short-term health problems (e.g. migraine, difficulty concentrating, dizziness and pain) and eventually long-term physical sequelae (e.g. lumbago, inflammation of cartilage and osteoarthritis).
The experience of NIHON KASETSU in measuring vibrations in very diverse construction projects has led to the development of a simple and effective methodology for recording vibration levels with the eComo monitoring system.
The system allows for the analysis of specific activity during the duration of the project, with threshold values being able to be established remotely and automatic alerts received when these are exceeded.
To control vibrations transmitted outside the work perimeter, in nearby residential areas, for example, the number of sensors and their positions need to be properly determined.
In addition, to measure vibration properly, the vibration sensor, the accelerometer, must be properly supported on a rigid surface and in the same plane as the vibration to capture the movement in the perpendicular axis, so that no other element can cause mechanical interference.
G’day there! A new skate park is going to be build not far from my neighborhood and my cousin is one of the people in-charge of the project. I really appreciate your advice on controlling the amount of vibration throughout a construction process to reduce the risk of brain discomfort among those who are nearby. I’ll remind him about this important detail so he can take appropriate actions moving forward.
Oh, hello. When you talked about the many sorts of laws that set maximum authorized levels to minimize the impact of vibration and sound on their surroundings, it gave me a huge sense of relief. My uncle has decided to build a large warehouse next to his house starting next month and I’m sure the project would be extremely noisy. I hope he takes note of this matter and refers to a professional to monitor the situation.
