Environmental noise at high levels and inappropriate construction techniques used in conventional buildings in Brazil claim for a transition to better construction systems. Recently the Brazilian standard NBR 15575:2013 ...

Acoustic signals are distorted by vegetation, wind currents, or other sounds when transmitted through the environment. Consequently, vocalizations with features that optimize sound transmission or behaviors that improve ...

Many species use low-amplitude (soft) song during close range interactions with conspecifics, such as in aggressive encounters or courtship displays. It has been suggested that soft song is adapted to limit eavesdropping ...

When designing an environment or an equipment it is often necessary to consider its acoustic conditions, such as the amount of sound that transmitted to nearby environments, as there is often a need for sound insulation, ...

This paper presents the design, construction and evaluation of an acoustic enclosure, which was used as basis for the study of the sound insulation caused by these devices. An acoustic enclosure is a passive noise control ...

The Acoustic Adaptation Hypothesis posits that habitat characteristics influence the structure of animal vocalizations and that animals will vocalize and display behaviours optimized for sound transmission. White-eared ...

For the purpose of solving the problems of vibration transmission and sound radiations in ships, synchrophasing control technology was presented. The phases of multiple rotating or reciprocating machines installed on a ...
