Controlling the level of noise in a work is not yet an obligation constructor. However, taking some measures to help improve relationships with neighbors can be beneficial. With a minimal investment can create noise barriers to reduce the inconvenience for those living near the work and those who work in it.

"While existing rules do not require Buenos Aires noise impact reports for the routine work, monitor acoustically the different tasks and liaise with the neighborhood avoids unnecessary conflicts with the consequent loss of time and money in surveys and trials, "says architect Alejandro Badani, a specialist in acoustics.

The construction sites are not reached by the provisions of the 1540-1504 Law of Noise Pollution Control of Buenos Aires, which establishes a registry of potentially noisy activities to be subject to control.

However, that same law divides the city into seven areas of acoustic sensitivity for fixing maximum noise levels for day and night (60 and 50 dB respectively for a residential area). Trucks, backhoes, generators, saws, over 70 dB during operation.

"The building construction is equivalent to a factory in the open, it is clear that cause inconvenience to the neighborhood, but you can minimize its impact, "said Badani. He adds: "The noise level is different for each stage of construction due to the work and machinery to be used." The movement of soil, concrete and endings are some of the most annoying tasks .

One of the simplest measures to mitigate noise at work is the use of machinery and equipment in good condition and privilege electric motors. Furthermore, having the sources of noise, like compressors and generators, as far away as possible work area. A screen of phenolic or plastic wrap around the machinery may block the noise. The

acoustic enclosures must withstand inclement weather and provide sufficient insulation so that the sound that crosses not add to that is diffracted. You can also coat the inside with an absorbent material. Another recommendation to lower the noise is prepared off-site reinforcement or using cutters and scissors instead of saw or grinder. Finally, it is recommended plan schedules and notify neighbors before performing very noisy.
