Análise de performance de um enclausuramento por meio de medição de potência sonora em câmara reverberante
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2023-03-21)
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 ...
Analysis of sound propagation for outdoor emergency speakers networks
(Institute of Electrical and Electronics Engineers Inc., 2017)
In this work we show the results of analysis of propagation of sound waves applied for an alert system in the river Chili, in Arequipa city. We used mathematical models, ISO standards, geographical, demographical and ...
Generating sound stimuli with given emergence level and low frequency content by mixing recordings
(S Hirzel Verlag, 2017-09)
Noise annoyance and other effects of noise are reasonably correlated with A-weighted sound levels. Currently, the influence of low-frequency content and of sound emergence level (i.e. the sound level difference between ...

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, ...
Eavesdropping avoidance and sound propagation: the acoustic structure of soft song
(2017-12)
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 ...
