Infrared spectroscopy (IRS) is a technique used to analyze individual substances in isolation or a mixture, using their spectral information. IRS is based on the measurement of the wavelength and ...

With SoundFlow, models of multi-layered wall constructions can be created for predictions of absorption, reflection and transmission. Wall construction simulation is set up via a few clicks a ...

Many asymmetric absorbers are currently based on a single-port system, where sound enters one side and is absorbed before a rigid wall. In this design, however, light and air are unable to pass ...
