Elevating the quality of life through efficient noise protection
In today’s urban landscape, environmental noise stands out as a prominent contributor to the escalating problem of noise pollution. Areas exposed to traffic-related noise often exceed 75dB. The repercussions of these noise levels on human well-being primarily materialize as noise-induced stress, influencing individual performance, and fostering enduring negative effects.
Effectively addressing noise through protective measures can significantly contribute to an improved quality of life.
What are the relevant factors of noise it’s perception?
- Sounds, tones, and noises collectively shape the auditory experience.
- The human ear has limited perception within specific frequency ranges.
- Sound pressure delineates the intensity of the sound.
- Hollow spaces within a building can give rose to resonances, which play a crucial role in building acoustics.
- Sound insulation denotes the ability to resist the transmission of sound.
Building Requirements for Sound Insulation and Noise Protection:
Noise pollution from external sources depends on factors such as time of day and the building's location, especially in proximity to traffic hubs like airports, railways, or industrial areas. The building requirements may differ depending on the designated use, such as residential areas, offices, or healthcare facilities.
Selecting the ideal construction of the exterior wall is crucial, emphasizing the effective reduction of airborne sound across the entire structure, including the exterior wall and windows.
The Positive Impact of Ventilated Facade Construction: Ventilated facade construction emerges as a highly effective solution against noise pollution, leveraging the acoustic properties inherent in its components.
The sound-absorbing mass of the wall structure is enhanced by the inclusion of thermal insulation. Thermal insulation, exemplified by ROCKWOOL insulation, absorbs and dampens sound waves penetrating through facade panels and the rear ventilation space, outperforming foamed insulation materials.
The rear ventilation space, with a minimum of 20 mm between facade panels and insulation, amplifies the mass-spring-mass principle's effect, reducing resonance and dispersing vibrations.
The cladding material's weight per unit area, rigidity, and joint arrangement can also positively influence sound, further enhancing the overall acoustic performance.
