ACOUSTIC PANELLING SYSTEMS

Product catalog summary

Acoustic Quality and Design: Acoustic quality is essential in room design, influenced by geometry, materials, and their arrangement relative to sound sources. Proper design requires defining the space's intended use, as different environments like theaters, offices, and restaurants have unique acoustic needs. The goal is to ensure sound signals convey messages clearly, whether music or speech.

Challenges and Solutions: High noise levels can hinder communication, leading to increased sound pressure as people raise their voices. Controlling reverberation is key, with reverberation time optimized using sound-absorbent materials to create a well-defined acoustic environment.

Sound-Absorbent Systems: Various systems, including milled and drilled, mixed and suspended, and radiant sound-absorbent systems, reduce reverberation time and enhance acoustic clarity, contributing to better communication and comfort.

4akustik System: This system uses MDF slats for walls and ceilings, offering high sound-absorption performance. It adheres to strict health and safety standards, including low formaldehyde content, and is available in versions with and without fire reaction certification.

Product Overview: The 4akustik sound-absorbing system is designed for walls and ceilings, made from MDF slats that are coated, lacquered, or veneered. It is based on Helmholtz resonator theory and sound dissipation through porosity, offering high sound absorption and health and safety standards.

Specifications: The 4akustik panels are available with EC certification for fire reaction class B-s2,d0 and comply with the Japanese F4 star certification for low formaldehyde content according to JIS standards. An alternative version without fire reaction certification and with E1 formaldehyde emissions is also available.

Installation Procedures: Panels can be installed on walls and ceilings using a simple, adhesive-free method involving screws and sliding clips, allowing for easy removal and adaptation to environmental conditions. Curved installations are possible by milling the rear of the slats to provide elasticity.

Acoustic Performance: Acoustic tests are conducted according to UNI EN ISO 354:2003 standards. The document provides sound absorption coefficients across various frequencies, highlighting the system's effectiveness in different acoustic environments.

Additional Features: The S-Top accessory enhances the functionality of the 4akustik system by providing a versatile attachment compatible with specific panel models. It is designed for easy installation and repositioning without the need for additional drilling.

Letwood System: Letwood is a modular ceiling and wall system designed for high-end design, acoustic quality, and comfortable decors. It is ideal for spaces such as airport lounges, hotel foyers, public transit areas, bars, clubs, and stores. The system offers a unique synthesis of aesthetic style and acoustic quality, allowing for visually and acoustically appealing spaces.

Specifications: Letwood panels are available in a square format (60x60 cm) and offer modularity and interchangeability. The panels feature four different milling patterns, providing creative options for architects and designers. The panels are made from MDF with a melamine finish and have a low formaldehyde content (E1) or very low emission (F**** class).

Installation: Letwood panels can be mounted on walls or ceilings. The installation uses straight metal profiles with an omega section, and panels are fixed using special metal plates. The system allows for a total thickness of 36 mm and a weight/surface ratio of about 12 kg/m². Ceiling installation involves flat or channel metal profiles attached to the existing ceiling.

Acoustic Performance: The panels provide high sound-absorbent acoustic performance through through-hole perforation, porous texture, and membrane absorbers. Different milling and rear perforation types correspond to varying acoustic capacities. Sound absorbency coefficients are available for each standard model and installation method.

Fire Safety: The panels are available in EC-certified, class “B-s2,d0” fireproof material, compliant with current Eurocodes for construction materials.

Sound Absorption Systems: The document outlines two methods for measuring sound absorption: the American NRC and the European Alpha Weighted. Porous absorbers like mineral wools and foams are effective at medium and high frequencies. Resonant absorbers use a thin panel to selectively absorb energy at its resonance frequency. Cavity absorbers, or Helmholtz resonators, provide selective absorption around their resonance frequency, typically between 50 and 400 Hz.

Reverberation Chamber: In collaboration with the University of Udine, the Fantoni Group developed a reverberation chamber for measuring the sound absorption properties of materials. The chamber's innovative design provides a state-of-the-art tool for acoustic research and product development.

Acoustic Experience: Fantoni has created special installations for retail outlets to demonstrate the acoustic performance of their products, allowing customers to experience the difference between untreated and treated environments with Fantoni's sound-absorbing panels.

ACOUSTIC PANELLING SYSTEMS La qualità acustica è un elemento fondamentale nella progettazione degli ambienti e dipende principalmente dalla loro geometria, dal tipo di materiali presenti al loro interno e dalla loro disposizione rispetto alle sorgenti sonore, dalla riverberazione del suono e dal livello totale del rumore di fondo. D’altra parte per una corretta progettazione acustica di un ambiente è necessario definire a priori la destinazione d’uso per cui esso verrà impiegato. Differenti sono infatti le caratteristiche che deve possedere un teatro rispetto ad un auditorium, un ufficio rispetto...
