Buildings which have high levels of sound pollution and facades that do not isolate outside noise are often found in large cities. This situation affects people s sound comfort and health. In connection with that, there ...

Variations in communication systems profoundly affect bird evolution. Vocalizations mediate species recognition and therefore intra-specific variation may lead to reproductive isolation, ultimately resulting in speciation. ...

Geographical variation of bird vocalizations may be related to factors influencing sound production and sound propagation. If birds, e.g. the Great Antshrike (Taraba major), produce vocalizations that develop normally in ...

This work aims to determine the acoustic isolation to aerial noise of glasses used in the civil building, as insulations or frames, of different types and thicknesses, in a simple form and composing double glasses. This ...

The present work evaluates the acoustic isolation of a wall of plates pre-molded, constructed with recycled material (rubber of tires), used in popular constructions the two decades, in the city of Santa Cruz do Sul - RS. ...

Why study acoustic communication? And why in subterranean rodents? There are several reasons for studying acoustic communication in this particular group of mammals. First, acoustic communication is of great importance to ...

This article aims to identify acoustically insulating materials, to choose the best option among the materials found in order to acoustically isolate a indoor firing range, thus providing the shooter and the person outside ...
