Glass, concrete and steel are being used more and more in modern architecture. These clean surfaces reverberate which is often interpreted as an uncomfortable noise. This can be counteracted by fabrics. They absorb the sound and thus reduce noise pollution. In addition, they can optimize the acoustics of the room and positively influence communication. Be it at work, in a restaurant, in a hotel room or in the theatre, good room acoustics foster the well-being, communication and output. There are many possibilities to influence room acoustics with the help of textiles. They can be used as curtains, chairs, room separators, wall covering, seiling suspension, as a panel or an upholstery fabric. With its comprehensive acoustic collection, DELIUS creates the peace that we humans need to feel well at our work desk or during our leisure time.
Basically, room acoustics are in relation to the sound in the room. The sound absorption coefficient, which describes the property of a material to absorb sound, is measured. This is measured in a reverberation room according to DIN EN ISO 354 and divided into absorber classes A-E.
The DELIUS Acoustic Collection covers the complete area of textile furnishings. It comprises different blackout fabrics, plains with and without structures, exclusive velvets, modern wool fabrics and transparent sheers.
Transparent acoustic fabrics
Light transparent acoustic fabrics are a novelty for the contract market; they offer a completely new way of designing offices, hotels and restaurants. When the curtain is drawn, its sound-absorbing property becomes apparent; at the same time, it serves as privacy protection and deflects glaring sun light. The natural daylight in the room creates a pleasant atmosphere. The sheers are room-high (330 cm width) and can thus be mounted without a seam.
Apart from the darkening properties the DELIUS Dimout fabrics have outstanding acoustic properties. Their sound absorption volume is less than w 0.65 / class C. They thus create a pleasant peacefulness and darkness in hotel rooms and conference rooms. The room acoustics and the light situation during a beamer situation are perfect.
Velvets and wool fabrics
Classical acoustic fabrics are velvets and wool fabrics. Velvets have a luxurious appearance and offer excellent acoustic properties thanks to their soft surface. It is exactly for this reason that one finds them frequently in theatres and cinemas. Wool fabrics are equally effective. They are also sound absorbing and have a more puristic appearance.
Furniture is also able to absorb sound. Fabrics with acoustic properties can increase this effect. Sound-absorbing upholstery fabrics can be velvets, wool fabrics and fabrics with structured surfaces.
Fabrics for acoustic panels / sound absorbers
Acoustic panels are available in different forms; they exist as room partitions, counter displays, display boards, ceiling attachments, etc. Absorbers absorb sound waves up to 100%. The fabric primarily serves a decorative purpose. With its colourful and structural variety, it sets highlights in every room. Absorbing fabrics require an acoustic transparency so that sound waved can penetrate them.
