Frequency

Frequency is the number of oscillations/pressure variations in a given time period. The unit of frequency is Hertz (Hz), where 1 Hz corresponds to one oscillation cycle per second. The human ear can perceive frequencies between 16 and 20,000 Hz. A low tone is produced by slowly oscillating sound waves. The faster the oscillations, the higher the sound perceived.

soni COLOR RD
soni COLOR RD – Acoustic inserts for grid ceilings soni COLOR RD is our high-quality acoustic insert for grid ceilings measuring 620 x 620 mm, which can be easily inserted into existing suspended standard grid ceilings or Odenwald ceilings (OWA). The elements consist of a sound-absorbing white polyester fleece, laminated with a thin, mottled felt surface in current trend colours. They thus combine aesthetic design and effective sound absorption in one product. Grid ceilings – function and advantages Grid ceilings consist of inserts in a supporting grid and are mainly used in offices, schools, medical practices, restaurants and public buildings. They enable flexible room design, easy access to cables and the integration of lighting, ventilation or acoustic elements. A common problem with grid ceilings is excessive reverberation, as the smooth ceiling surfaces reflect sound. soni COLOR RD noticeably reduces reverberation and noise levels, creating quiet, pleasant working and learning environments. Effective room acoustics with soni COLOR RD soni COLOR RD acoustic elements significantly reduce the sound level in a room and help to improve room acoustics in offices, meeting rooms or doctors' surgeries. soni COLOR RD is also a proven acoustic element for noise reduction in schools, daycare centres and nurseries. soni COLOR RD acoustic elements significantly improve room acoustics, reduce disturbing noises and increase speech intelligibility. They are ideal for: ✔ Offices & meeting rooms – less noise, better concentration ✔ Medical practices & care facilities – more pleasant room climate for patients and staff ✔ Schools, daycare centres & nurseries – targeted noise reduction for concentrated learning ✔ Restaurants & canteens – quieter atmosphere for guests ✔ Home offices & living spaces – comfortable, relaxed environment Fire protection and standards soni COLOR RD complies with the fire standards required for the construction industry in accordance with DIN EN ISO 13501-1. This means that the acoustic elements can be used safely in ceilings and as wall cladding – wherever fire protection regulations must be observed. Installation instructions – flexible and simple ✔ Installation in grid ceilings: The elements are simply inserted into the grid ceiling – no additional fastening is necessary. ✔ As wall absorbers: For installation on smooth, clean surfaces, we recommend our soni SPECIAL ADHESIVE ✔ Alternative installation: soni VELCRO TAPE can be used for removable fastening. Note: Only suitable for wall mounting, not for ceilings ✔ Or with WIKO spray adhesive, which is also very well suited for installing wall absorbers Design meets function Thanks to its modern felt surface and wide range of colour options, soni COLOR RD can be creatively integrated into any interior design. This harmoniously combines acoustic measures and interior design, ensuring a pleasant noise level in offices, educational institutions and catering establishments.

soni COMFORT
soni COMFORT is a very hard-wearing sound absorber made of a white PES non-woven fabric with exceptionally good sound-absorption capacity. In addition, soni COMFORT offers excellent fire-resistance values. soni COMFORT has been tested successfully according to the DIN 4102 fire safety standard and is classified as fire-retardant (B1). Therefore it is the material of choice for all applications requiring both an effective noise reduction and full compliance with fire safety regulations. When used as a ceiling element, soni COMFORT also fulfills the impact-resistance requirements according to DIN 18032-3 and is ideally suited for use in sports facilities and gymnasiums. What is more, soni COMFORT is aging-resistant, free of mineral fibers and physiologically perfectly safe. All this makes soni COMFORT a true all-rounder for effective sound-conditioning measures in a wide variety of room types. For covering entire wall or ceiling surfaces we recommend using soni COMFORT F. While soni COMFORT has plain edges, soni COMFORT F has beveled edges all around (10 x 10 mm), creating a beautiful visual effect when installed edge to edge. Additional advantage: The resulting pattern helps conceal any uneven patches on the ceiling or wall. If necessary, soni COMFORT and soni COMFORT F can be cut to the desired size and shape with a carpet knife or a keyhole saw with a blade suited to cutting soft materials. For fixing the absorber panels on the wall or ceiling we recommend our soni SPECIAL ADHESIVE, our soni VELCRO tape or our soni RING HANGER.

soni PROTECT
Out soni PROTECT noise absorber is made from an open-cell melamine foam (Basotect®) with outstanding sound-absorption capacity. Use soni PROTECT to significantly improve the acoustic conditions in interior spaces. With soni PROTECT acoustic panels fixed to ceilings and walls, your room will be much less reverberant.  soni PROTECT has been tested successfully according to European as well as German fire safety standards and can therefore be used wherever you need to reduce the noise level with materials that meet strict fire safety regulations. What is more, soni PROTECT is aging-resistant, free of mineral fibers and physiologically perfectly safe. All in all, an absolute classic for optimizing acoustics conditions in buildings. For edge-to-edge installation we recommend using soni PROTECT F. It consists of the same material as soni PROTECT, but has beveled edges all around, which make for very neat joints and an attractive surface design while actually helping conceal any uneven patches in the ceiling or wall surface. Please note: We do not recommend soni PROTECT for use on wall areas that are liable to be hit or touched, as the sound insulation panels are sensitive to mechanical stress. soni PROTECT and soni PROTECT F can easily be cut to the desired size with a carpet knife. For fixing the absorber panels on the wall or ceiling we recommend our soni SPECIAL ADHESIVE. Basotect® is a registered trade mark of BASF SE.
