THINK CITIES AND BUILDINGS THROUGH: noise reduction approach

The general idea is to design a city with “noise controlled concept” Urban nuisances and noises inside buildings.

Urban acoustics is linked to the level of economic development of a country. In other words, more a city develops in infrastructures which means more mobilities (cars, motorbikes, trains, metros, planes, …), more it is confronted with the problem of noise. It affects medium-sized cities, large metropoles and megalopoles: Abidjan, Cotonou, Lomé, etc …
We need to think of future cities and act right now to limit :
the impact of noise pollution on the urban scale.

To achieve this, it is necessary to raise upstream awareness of the harmful and irreversible consequences of noise and the prospects of its resorption :

• Deafness, partial or permanent deafness,
• Stress, fatigue, loss of efficiency and productivity,
• cardiovascular illnesses,…
• Public health problem,

In existing buildings or buildings to be built, care should be taken to ensure the well-being of the occupants.
For this reason, the preliminary studies and technical solutions proposed by Gérard Kotingan and his team of acoustic engineers at abc décibel, are likely to ensure isolation to airborne noise from the outside, impact noise, noise from field equipments.
More generally, to bring a well-being to citizens …
