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 …

Ultraviolet radiation (UVR) and noise are the ubiquitous environmental hazards with
considerable detrimental effects on the physiological and psychological health of humans …

Nowadays the use of porous polyurethane sponge (PPS) is very common for sound
absorption, thanks to its light-weight feature and easy fabrication. However, in many …

Traffic noise has been regarded as one of the most annoying pollutions that induce severe
hazards to human health, both physiological and psychological. The commonly used fibrous …

Sound absorbing materials are used in buildings to dissipate sound energy into heat using
viscous and thermal processes. Sound absorbers increase the transmission loss of walls …

This paper investigates the acoustic absorption capability of a multilayer micro-perforated
panel absorber (MPPA) whose front layer is produced by additive manufacturing. The MPPA …

Noise is an environmental pollutant with recognized impacts on the psychological and
physiological health of humans. Many porous materials are often limited by low sound …

A sound-absorbing periodically arrayed structure (SPAS) based on the combined effects of
cavity resonance and impedance transition is designed. Different types of polyurethane …

Antibacterial sonothermal therapy (ASTT) is attractive for treating implant‐associated
infection, which addresses the limitations of poor penetration of photothermal therapy …

Microperforated panels are light, clean and tunable sound absorbers, which fundamentals
were already established in the previous century. They consist of a distribution of minute …
