Noise Impact Assessment

2. Noise Impact Assessment
For construction works, the noise assessment is extremely important for the well being and
comfort of the closest neighbors. Surrounding environment is also affected by noise, so
sensitive areas become commercial / industrial areas without any study of noise impact,
and without any record of previous data.
The ideal monitoring would be:
. First – Noise study before the construction
. Second – Noise study during the construction
. Third – Noise study after the construction
This way you will be able to see the impact that the construction had on the environment
of the area and compare the data in order to improve future projects.
When this process is not possible, the surrounding buildings or neighbors should be
protected during resting hours with an easy and fast monitoring solution, so the building
authority can give or retrieve the construction license during night works.
The noise impact in residential areas should be minimum and constantly monitored so that
the authorities can create solutions and be aware of what is really happening.

3. Noise Impact Assessment
For ideal construction works, the noise levels are not
recommended to go over (examples):
Day (8am to 7pm) – No Limit
Evening (7pm to 11pm) – 3 dB
Night (11pm to 8am) – 1 dB
For the authorities to have a comparison, a
monitoring should be done when no works are being
done, so as an example here are some levels for your
understanding:
No works Working
Day 72 80
Evening 70 73
Night 67 68
If levels are exceeded, authorities can issue Fines or even retrieve the “extended
hours of work” License.

4. Noise Impact Assessment
To be able to monitor, it will be needed a noise level meter, with outdoor capabilities.
Authorities can request the Construction companies to have this equipment installed in
order to approve the “extended working hours” license.
This equipments should be connected to an online platform where Only the Police and
Municipality can have access to constantly check the data, apply fines and/or retrieve
licenses.
The noise level meter should be installed the closest to the neighbor as possible.

5. Noise Impact Assessment
NoisePlatform is an on-line platform that displays and dynamically analyses, in real time,
the noise measured by a mixed network of sensors and terminals that can monitor the
entire area affected by noise-generating activities.
Authorities will have access to this encrypted platform, where only they will be able to open
each monitor readings in Real Time.

9. CESVA TA120
Monitoring sensor for sound level based on a
continuous measurement (24h).
The TA120 is characterized by its class 1
measurement accuracy (IEC 61672).
It has outdoor kit protection + IP65.
Thanks to its light weight and structure allows easy
installation
The sensor is compatible with both Noiseplatform as
other open source platforms.
