Nowadays, there is a vast need to calculate performances of timber constructions. Usually,
simulations are implemented to predict buildings elements final performances. Here, the …

Global warming and noise pollution have emerged as the most serious environmental
problems ever to confront humanity. In recent years, the use of natural fibers as thermal …

This definitive guide covers the design and application of absorbers and diffusers in
acoustics. Surface diffusion is a relatively young subject area, and diffuser design …

The purpose of this paper is to present and discuss a range of in-situ and laboratory
methods can be used to measure the morphological characteristics of porous materials. In …

This paper presents an acoustic metamaterial, coiled-up structure with porous lining (CSPL),
which is constructed by adding porous material lining to a coiled-up air channel for the …

Sound-absorbing and thermal-insulating materials have a noteworthy role in the
performance of buildings. In recent years, there has been a significant focus on utilizing …

The use of natural fibers in the buildings and construction industries as a sustainable and
biodegradable product with the aim of noise pollution control has attracted the attention of …

An increasing interest in the possibilities of converting agricultural wastes to value-added
products has emerged. Annually, 200,000 tons of date palm waste are generated, which are …

Conventional sound absorbers can hardly own the good performance of low-frequency and
broadband absorption simultaneously. In order to combine these two functions into one kind …
