The Relevance of the Low-Frequency Sound Insulation of Window Elements of Façades on the Perception of Urban-Type Sounds

Buildings, 2023
The sound insulation of the façade and its elements is a very important characteristic, as it largely determines the degree of sound protection of the building’s interior from external noise sources.

Integrated Photogrammetric-Acoustic Technique for Qualitative Analysis of the Performance of Acoustic Screens in Sandy Soils

Sensors, 2019
In this work, we present an integrated photogrammetric-acoustic technique that, together with the construction of a scaled wind tunnel, allows us to experimentally analyze the permeability behavior of a new type of acoustic screen based on a material ...

A tunable acoustic barrier based on periodic arrays of subwavelength slits

AIP Advances, 2015
The most usual method to reduce undesirable enviromental noise levels during its transmission is the use of acoustic barriers. A novel type of acoustic barrier based on sound transmission through subwavelength slits is presented.
