Stretch Acoustics
Stretch Acoustics is a leader in stretch ceiling installations, offering an innovative system with versatile design options. The system is available in various colors and finishes, is hygienic, non-toxic, recyclable, and comes with a 12-year guarantee. It meets the Euroclass fire standard B s1 d0.
Sound Absorption Technology
The system uses a micro-perforated membrane as a resonance absorber, converting sound energy into heat. Acoustic performance is influenced by perforation size, sheet thickness, and air volume behind the material, allowing customization for specific acoustic needs.
Measurement of Sound Absorption
Sound absorption was measured according to ISO 354:2003 in a reverberation room, testing various scenarios including different cavity depths and acoustic insulation. Results are presented as sound absorption coefficients across frequencies.
Case Study: Oslo Opera House
Stretch Ceilings installed over 3000 square meters of acoustic panels at the Oslo Opera House, using bespoke acoustic Matt White panels to enhance architecture and improve acoustics by reducing noise reverberation.
Key Findings
- Non-perforated ceilings with no insulation showed lower sound absorption coefficients.
- Perforated ceilings with glass wool insulation demonstrated higher sound absorption, especially at mid to high frequencies.
- Micro-perforated materials significantly enhance acoustic performance.
Conclusion
Stretch Acoustics offers a flexible and effective solution for sound absorption in architectural spaces, with customizable options for specific design and acoustic requirements.
The document highlights the benefits of Stretch Ceiling Acoustic systems in enhancing acoustic comfort in environments like atrium foyers and restaurants, using micro-perforated sheets to reduce reverberation and improve sound absorption.
Specifications and Features
The system features micro-perforated material that enhances sound absorption through air friction and resonance. Available in various colors and finishes, the Matt White finish offers high light reflectance. The material is water-resistant, durable, and requires no ongoing decoration. It complies with European Classification EN13501-1, is non-toxic, and fully recyclable.
