Acoustic material testing capabilities include:
- Density (kg/m3)
- Air Flow Resistivity (Ns/m4)
- Alpha Cabin (small reverberation chamber)
- Impedance tube testing – acoustic absorption and transmission loss
Autins Technical Centre is the core provider of technical knowledge, testing services and product innovation for all Autins Group companies. Our laboratory has a range of mechanical, thermal and acoustic testing equipment to assist in the provision of technical information and data to Autins Group and its customers.
Established in 2016, Autins Technical Centre is the core provider of technical knowledge, testing services and product innovation for all Autins Group companies. Headed by Dr Kathy Beresford, who has a PhD in Multichannel Automotive Audio, her team of acousticians hold extensive experience in nonwovens, polymers, material testing, acoustics and automotive NVH (noise, vibration and harshness).
Inverse and indirect software methods for characterising Biot parameters:
These parameters are common for modelling porous materials using statistical energy analysis (SEA) or finite element analysis (FEA) packages
In addition to acoustic testing services we also offer finite transfer matrix method (FTMM) acoustic modelling. This takes material Biot parameters and uses them to predict acoustic performance. We use acoustic modelling to generate expertise and scientific rigour for customer projects and product developments
