S|Twist| acoustic silencers
EFFECTIVE AND COMPACT ACOUSTIC SILENCERS
Silencions s|Twist| are compact acoustic silencers that reduce noise wherever free air flow is required. Their geometry reduces noise by up to 20 dB in selected frequency ranges.
POSSIBILITIES OF STWIST ACOUSTIC SILENCERS
Place s|Twist| behind a gravity ventilation inlet in the wall or as covers for ventilation openings in bathroom doors. We can tune them to the frequency range that is most bothersome for you.
Effectiveness
Up to 20 dB of noise reduction in the selected frequency range
Air flow
Unobstructed, free air flow
Flexibility
Ability to tune to the most problematic frequencies
Example applications
Gravitational ventilation, grilles, culverts, door inlets
Let’s talk about specifics
Cicho wszędzie
Cichy przepływ powietrza
Silencions sTwist to metamateriały dedykowane wszędzie tam, gdzie występują wszelkiego rodzaju przepusty, kanały i otwory wentylacyjne.
Najlepsze efekty uzyskasz tam, gdzie przepływ powietrza nie jest wymuszany mechanicznie, a odbywa się swobodnie (np. wentylacja grawitacyjna). sTwist działa na zasadzie rozpraszania fali dźwiękowej, nie powodując przy tym zaburzenia przepływu powietrza.
INNOVATIVE METAMATERIALS
The s|Twist| acoustic silencer is a system that works on the principle of destructive interference of acoustic waves, which occurs through the appropriate shaping of spiral channels.
Its geometry can be modified to achieve effectiveness in selected frequency ranges.
Example comparison of the sound level of a source emitting a white noise signal located behind the channel. The black line shows the measurement result for the case of the hole closed with a mask, the pink line shows the result obtained after applying the sTwist silencer tuned to the frequency range 1000 Hz – 1600 Hz.
ACOUSTIC COMFORT WHERE YOU NEED IT
COMPACT S|TWIST| ACOUSTIC SILENCERS
| Effective acoustic attenuation by up to 20 dB in the selected frequency band |
| Highest efficiency in the low frequency range, ideally below 1000 Hz |
| Compact dimensions (30-150 mm) and weight less than 100 g (depending on version) |
| Adapted to the characteristics of the noise source |
| Free air flow thanks to the open structure |
| Numerous applications – from domestic to industrial |
Where will an acoustic silencer help?
Example applications
Replace the regular air vent cover with Silencions sTwist and enjoy silence with air flow. We can make an acoustic silencer for you in various shapes, depending on the function.
Ventilation openings and openings in doors and walls (e.g. bathroom doors)
Window vents will reduce unwanted noise from outside (e.g. planes, trains, trams)
Ventilation holes in furniture and device casings (e.g. refrigerators in furniture)
Ventilation grilles are particularly effective in the case of gravity ventilation
