Silphon® acoustic cylinder Basotect® B white for excellent sound absorption across a wide spectrum.

The Silphon® acoustic cylinders are made of Basotect® B white melamine resin foam and, thanks to their low weight of approx. 9kg/m3, can be installed easily and without major effort. The Silphon® acoustic cylinders have very good sound absorption properties over a wide spectrum. A further plus point is the fulfillment of the fire protection standard according to DIN 4102 / B1 as a result Basotect is a flame-retardant material and also achieves above-average results in surface insulation and thermal insulation. The standard dimensions of the acoustic cylinders are 500 mm long with a diameter of 150 mm. On washes, we can also produce customer-specific dimensions with our "swiss made" processing. The Silphon® acoustic cylinders can be easily mounted on the ceiling with the Vibra® suspension system or simply by means of hooks and nylon thread. You can find further information in our online-shop!

Frequently asked questions (FAQ)

Sound attenuation can be understood as the prevention of sound spreading through the absorption of airborne sound. The sound energy is converted into inaudible oscillation waves during sound absorption and as a result the reflection at a boundary surface is reduced. The acoustics within the room are improved and the noise is reduced.
In the mid to high frequency range, the existing furnishings of the room have a great influence on the reverberation time (sofa, carpet, curtains etc. are also absorbers). The use of additional porous absorbers can be useful in some places, but can also have a (very) fast negative effect and lead to a dull sound without natural dynamics. The upper frequency range is often already damped sufficiently well by the typical living room furnishings even before a planned optimisation of the room acoustics. With any acoustic measures, the main focus should generally be on the lower frequency range. Here a good and sufficient absorption is much more difficult to achieve
By using foam absorbers or foam bass traps, the reverberation time is reduced evenly across the entire frequency spectrum. Thereby a clearer and drier room sound is created. With the targeted use of absorbers, especially the disturbing initial reflections from the walls can be attenuated. The booming bass range can be specifically absorbed by bass straps. The sound image of the room through the use of absorbers becomes more homogeneous, softer and more lively.
The positioning of the acoustic elements on the wall and ceiling can be determined by using a mirror. Viewed from the listening position, the mirror is thereby shifted to the ceiling or wall until the speakers are visible in it. This is the perfect position for the most important acoustic elements. The Silphon bass traps are most effective when positioned in the corners of a room, because of the sound reflection from the ceiling, walls and floor. In principle you start with the lineup behind the boxes. The siphon bass traps can be stacked until the desired absorption is achieved.
Various factors can influence the room acoustics. For example, organic materials such as cork floors, wooden parquet, wooden ceilings or wooden walls are very well suited for pleasant room acoustics. Smooth concrete walls, granite floors and glass surfaces reflect sound very strongly and as a result are acoustically unfavourable. The interior design has a great influence on the sound spreading and as a result on the sound image in the room. A lounge seating area or a fitted carpet has an absorbing effect and a book shelf on the wall ensures that the sound is diffused. However, a specific improvement of the room acoustics can only be achieved by combining special Silphon acoustic modules.
Booming bass frequencies are often the cause of resonances of sound in the room. Silhouette bass traps effectively suppress the low frequencies and can contribute to an improvement and stop the annoying booming.
Materials such as concrete, glass or tiles are placed under sound-reflecting surfaces, which reflect the sound waves up to 100% and as a result do not insulate or absorb the sound. To reduce the volume (sound pressure) and the reverberation time in hard rooms, hard surfaces must be reduced and replaced by surfaces with sound absorbers that absorb the sound. The sound absorbers allow the sound waves to penetrate the structure and as a result the sound energy is converted into heat or kinetic energy.
In general, it can be said that the more surface of walls and ceiling is covered with foam materials, the less sound can be reflected from them. From experience, it can be assumed that approx. 40% - 50% of the ceiling and wall surfaces should be covered. With 100% cladding there is no more natural sound and this leads to unpleasant acoustics.
In general, the thicker the foam, the better and more efficient the sound absorption. If mainly middle or higher frequencies have to be optimized, good results can be achieved already from a thickness of about 30 mm. If low frequencies (bass tones) are involved, thicknesses from approx. 50 mm are advantageous. In general, it should be noted that the lower the frequencies and the higher the room, the thicker the foam panels should be. If a material is too thin, it only absorbs treble. If the material is thicker, it also absorbs low frequencies
Basotec? melamine foam has the BKZ 5.2 (hardly inflammable with medium smoke formation)
Our melamine foams Basotect? meet both of these requirements in equal measure, highly sound-absorbing and with very good thermal insulation properties.
Small air inclusions or blowholes on the foam top of Bastotec laminate foams can occur and are created during production. Unfortunately these cannot be prevented. However, the air inclusions have no influence on the absorption capacity.
The melamine foam standard panels are supplied as untrimmed raw panels. The ordered usable dimensions are guaranteed, but protruding material (foam, fleece, SK-foil etc.) is possible.
