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 properties.
