Fibrous materials have been widely used in noise reduction due to the porous structures. In
this review, available studies regarding the prediction methods of acoustic absorption …

Concrete is the most common building material; therefore, when designing structures, it is
obligatory to consider all structural parameters and design characteristics such as acoustic …

Effect of pore size and its distribution on the noise reduction coefficient of jute felt were
studied through capillary flow porometer and impedance tube. The inter-criteria correlation …

This manuscript reports on the effects of localized application of porous material on trailing-
edge noise of a circulation-controlled wing. This circulation-controlled configuration consists …

The acoustic performance of fibrous materials is mainly determined by its airflow resistance,
and it is a parameter of the resistance that the airflow meets through the materials. This …

The application of porous materials is a common measure for noise mitigation and in room
acoustics. The prediction of the acoustic behavior applies material models, among which …

The effects of cross-sectional shape, fiber density, and porosity of flax, jute, okra, sisal, and
wool fibrous assemblies on noise absorption coefficient have been investigated. The shape …

In the framework of the German Collaborative Research Center CRC 880: Fundamentals of
High Lift for Future Civil Aircraft porous materials as a means towards the reduction of airfoil …

This chapter includes the mechanism of sound absorption and the classes of sound
absorbing material to control the noise. The basic phenomena related to the reduction of …

When tailoring porous absorbers in acoustic applications, an appropriate acoustic material
model, as well as the relationship between the material model parameters and the …
