Definitions
As a variable we used the international unit of sound, the decibel. Using this unit of measurement we measured the noise that existed in various places and then proceeded to making the subsequent diagram (and then we were told to make the subsequent diagram). The areas where we took the measurements are as follows:

• the middle of the hall (room) 


• the corridor outside the hall


• the central part of the playground (yard)


• outside the canteen


• inside the staff room


• the principals office


• outside the school

Statement of limitations
The experiment was carried out once only and the duration of the experiment was less than a week. At the end of the experiment we placed the numbers we found on the pivot?, but it was impossible to compare the two
countries, since we came to the conclusion  that the school in Austria was located in a city where as ours is in the countryside.
Therefore, for us to be able to compare the measurements (we had found) we took the smallest measurement from each group and we subtracted it from the rest of the measurements. We came to the conclusion
again that the Austrians have more noise than us.
Based on the measurements we took we noticed that the school in Austria is in a city, also we
should mention that the school is new an industrial zone.


In contrast our school is located in the countryside, in a peaceful place far from big highways
and busy streets. It's apparent that if we compare the
two schools one can understand why the Austrian school
has more noise. The experiment we carried out serves a
social need (and since the school in Austria has more noise
there probably is the need). There is the possibility that the
noise and disturbance that exist there everyday affords
  the teachers and pupils. Taking into consideration the
above we came to the conclusion that it would help to
take immediate measures, for instance the installation
of double glazed windows, the construction of a
pavement round the school premises, banning of traffic
during lesson time (if this is possible).
From all the above we conclude that it is better for schools to be built outside the towns or in places where there
is not much traffic.

Since every research requires the carrying out of experiments so we, too, did some experiments.
In the course of the experiments several factors were not taken into consideration.
The factors are:
- The number of children.
- The season in which the experiment was carried out.
- The size of the classrooms.
- The time the experiment was done.
- Weather conditions.
