Noise pollution has become a significant global problem in recent years. Unfortunately,
conventional acoustic materials cannot offer substantial improvements in noise reduction …

As sustainability is one of the main pillars in developing future cities, adopting natural
ventilation whenever possible is one way to reduce energy consumption, thus indirectly …

Ventilated acoustic insulation currently represents one of the most promising research
directions in applied acoustics. With the ongoing development and application of acoustic …

Achieving sound attenuation across a broad frequency range while maintaining adequate
ventilation remains a significant challenge in acoustic engineering, as there exists a rigid …

The interest in phononic crystals and acoustic metamaterials has been an intensive subject
of research in recent years. Finding a robust way to significantly expand or actively control …

This article puts forward theory and design approaches for three thermally controlled
subwavelength acoustic topological insulators. They are presented by immersing arrays of …

Efficient broadband silencing of low-frequency sound (< 1000 Hz) while retaining the fluid
free-flow remains a challenge in acoustical engineering. Here, a ventilated acoustic barrier …

We revisit the modelling of labyrinthine metasurfaces with space coiling design. To do so,
we use homogenization theory which allows us to replace the actual structure by a slab filled …

Resolving the trade-off problem between wave obstructing and flow transport is an intriguing
but challenging task that may find potential applications in many noise control scenarios …

We demonstrate a flexible meta-curtain that can simultaneously block the propagation of
sound waves of selected frequencies and let air flow through freely. Such a meta-curtain is …
