Freudenberg Performance Materials Business Group produces Evolon, a highly effective lightweight microfilament nonwoven material that has superior acoustic absorption
and is used for vehicle interior noise and vibration control.

By increasing the salt to polymer mass ratio, acoustic absorption
of the PP foams improve and also the peak of the absorption curve moves towards higher frequencies.
From office chairs that are fully adjustable and adaptable to any kind of morphology to workstations that accommodate new workplace strategies by improving connections, supporting collaboration and increasing sharing, height adjustable desks and partition systems that offer acoustic absorption
and clever cable management, we offer smart business solutions to address the changing workspace requirements in today's private and open-plan environments.
The absorption mechanism of mineral wool is based on the viscous effects in the air contained inside the interconnecting pores which separate the fibres; the solid structure can generally be regarded as ideally rigid and stationary, and the acoustic absorption
as produced by the viscosity of the air, which is subjected to a process of alternate compression and rarefaction as a sound wave passes through it (Zwikker and Kosten 1949; Attenborough 1993).
The requirements are always to get good acoustic properties at low weights and you usually have only limited space for the parts--sometimes only 10 millimeters and you still want good acoustic absorption
Even the seating fabric on the planned comfortable armchairs will have an acoustic absorption
The result is a system that offers broadband acoustic absorption
Perfect for those toiling in call centre conditions--the cheerful and colourful Wannabetree by Bertil Harstrom for Glimakra provides both acoustic absorption
and visual privacy.
2, compared to the acoustic absorption
coefficient for concrete noise barriers.
Four artists were commissioned to create the pieces, including a blue and gold glass dome for the debating chamber floor, 44 slate slabs to form public seating outside the entrance, a 'wind hedge' made from 32 glass plates (Cardiff Bay is a windy place), and 600 fabric-covered acoustic absorption
