Agrupamentos Sonoros Plenos na Música de Simultaneidades Acústicas e Estruturais
(Univ Federal Goias, 2012-01-01)
The present article reflects about the concepts of linearity, space and acoustic complexity in the definition of sound grouping as a criticism to the linear concept of phraseology mainly when applied to the music of imitative ...

Sparse arrays and image compounding techniques for non-destructive testing using guided acoustic waves
(2013-06-01)
Piezoelectric array transducers applications are becoming usual in the ultrasonic non-destructive testing area. However, the number of elements can increase the system complexity, due to the necessity of multichannel ...

Molecular phylogenetics of Doraditos (Aves, Pseudocolopteryx ): Evolution of cryptic species, vocal and mechanical sounds
(Wiley Blackwell Publishing, Inc, 2020-12-01)
While bird vocalizations (produced by the syrinx) have been the focus of countless studies, mechanical sounds (produced by external body structures) have received much less attention. In particular, the evolutionary interplay ...
Construção e estudo de uma caixa acústica bookshelf
(Universidade Tecnológica Federal do ParanáCuritibaBrasilCurso de Engenharia de Controle e AutomaçãoUTFPR, 2018-12-04)
In order to bring the context of DIY (do it yourself) acoustic boxes closer to the brazilian reality, this paper intends to be used as help for a better understanding of this vast and complex subject. Starting off of the ...
Complex acoustic signals in Crossodactylodes (Leptodactylidae, Paratelmatobiinae): a frog genus historically regarded as voiceless
(Taylor & Francis Ltd, 2021-04-05)
Vocal sounds occur in most anurans and are often emitted as simple and stereotyped acoustic signals. Some frog groups, however, have complex signals and others can produce distinctive acoustic structures, such as purely ...
