Abstract:
Noise is unwanted sound reaching the ear; it leads to annoyance, disturbance of sleep and
other effects that may disturb the comfortability of the user of the building if not controlled.
In Rwanda, Rwanda National Police (RNP) as well as ministries, local government and
public institutions in charge always mobilize Rwandan citizens; especially churches, cinema
halls, studios, public buildings, entertainment halls and other sources of noise that sound must
be reduced as much as possible so that they may not disturb people who are not concerned in
those activities. However, it should be normal practice to reduce noise reaching people using
a building.
It is in that context that international regulations as well as Rwandan regulations state that
each building should have sound insulation for the provision of comfortability of users
against noise.
One of solutions to fight against that issue of noise that our proposal is based on, is to provide
materials that may retain internal noise in the building so that its intensity is reduced outside
the building or its rooms.
My research project is based on combining together materials taken as waste in our country;
which are cardboards and wooden chips using glue so that we shall come up with a new
product used as sound insulating material.
This report shows clearly how research was conducted.
The method used to collect data is quantitative where materials are to be collected by
sampling to make insulating board sample 1m*1m and then field tests are carried out. Also
qualitative approach was used while we did research in previous reports and books as well as
internet research to simulate our product with other available sound insulating materials.
After producing our material, we found that our material will be able to retain noise by
measuring sound level before and after placement of sound insulating material and will be
exactly the answer of the stated problem.
