MAXITO OCTAGONS AS A COPING FOR ACOUSTIC SCREENS

Road noise is a growing problem that negatively affects our health and quality of life. Maxito offers octagons, which are an effective addition to the concept of acoustic screens.

Octagonal sound reducers, or octagons for short, are elements that cope the wall of acoustic screens. This solution complements the function of the screen and further reduces road or industrial noise.

Application and operation of octagonal sound reducers

Octagonal sound reducers are elements that cope the upper edge of the wall of acoustic screens. They are often used to further reduce the level of unwanted traffic or industrial noise. The positive effect of octagons results from the phenomenon of sound wave absorption bent at the upper edge of the screen. The acoustic efficiency of noise-absorbing screens is directly related to the fact that the sound energy of the acoustic wave is bent by the upper edge of the screen, which causes the acoustic wave to scatter.

Mounting an octagon allows you to reduce the height of the screen while maintaining the same noise reduction effect. The acoustic efficiency, determined on the basis of the PN ISO 10847:2002 standard, which was estimated for acoustic screens with and without octagons, clearly indicates that the results of screens with reducers are lower by about 3 dB for 600 mm diameter octagons compared to screens without reducers. It should be remembered that a difference of 3 dB means a twofold reduction in noise.

Dimensions:

  • Adapted to the post spacing in the project.

  • The dimensions of the octagon cross-section are each time adopted according to the design or in accordance with the customer’s requirements, however, octagons with a height of 450 mm or 600 mm are most often used.

Main features of Maxito octagons:

  • Sound wave scattering: The octagonal shape acts as an acoustic diffuser. The specifics of the regular octagon favor the scattering of sound waves, which contributes to the reduction of the reverberation phenomenon and the equalization of the acoustic energy level.

  • Sound wave reflection: The shape of the octagon causes the sound to be reflected in specific directions, depending on the position of the octagon. In certain situations, such controlled reflection can be beneficial, allowing the sound to be directed in a chosen direction and limiting its impact on nearby built-up areas.

  • Reverberation reduction (resonance): The carefully designed octagonal coping of the screen helps to reduce reverberation (resonance), especially if they occur in a given place and are problematic.

  • Aesthetical aspects: The octagonal coping of the screen can also play an aesthetic function, giving the structure a more unique character.

  • Acoustic aspects: In order to obtain optimal results, the appropriate shapes and dimensions of octagons are selected depending on the frequency band of the sound. The octagonal shape can affect the direction of sound propagation. This can be beneficial when there is a need to direct sound in a specific direction or limit its impact on surrounding areas.
