Noise pollution can be defined as an excessive exposure to sounds and noises of an intensity greater than 65 decibels (dB), a threshold set by the World Health Organisation (WHO). Any sound above 75 dB is considered harmful to your hearing, while the pain threshold starts at around 120 dB. With noises beyond the threshold of 30 dB, it is even difficult to sleep.
Noise pollution is a major public health hazard; WHO estimates that 360 million people worldwide have a form of hearing loss.
How is noise transmitted? Noise is transmitted like a wave. When it is emitted, a vibration is transmitted into the air and when it is in front of an obstacle the pressure begins.
The vibration comes in the form of energy to the object that the noise is facing. The object in turn will begin to vibrate and transmit the vibration through itself.
Noise to spread requires the presence of a medium equipped with mass and elasticity. In a building this happens mainly in two ways: through the propagation by air, with no obstacles hindering its path, or by structural means, generated by mechanical impacts on walls and floors.
Acoustic stress, especially if also suffered at home, is one of the fundamental aspects that affect the quality of life.
This is why we as a company have decided to act on the causes of this stress.
What are these causes?
- music or TV set with a too high volume;
- street noise;
- trampling in the corridor;
- noisy neighbours;
- appliances in operation.
These are just the most common examples. But these are the ones that most affect our homes and the buildings in which we live.
To limit and eliminate these noises, we have designed the Stratifon panels.
