Revisiting the drivers of acoustic similarities in tropical anuran assemblages
(2021-01-01)
Acoustic signaling is key in mediating mate choice, which directly impacts individual fitness. Because background noise and habitat structure can impair signal transmission, the acoustic space of mixed-species assemblages ...
Simulação acústica de salas de aula em escolas de educação básica: uma proposta tipológica para prática musical
(Universidade Federal de Santa MariaBREngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia Civil, 2012-09-24)
The study of room acoustics is linked to the importance of sound inside a room, so the architectural characteristics of the internal space determine the acoustic
behavior. To get better acoustics of a room there are ...
Room acoustics: Idealized field and real field considerations
(Acoustical Society of America, 2018-05)
How is an acoustically diffuse field defined? To what extent are the equations of diffuse field theory valid? These are the questions addressed in this presentation. The answers are explained through more general theories, ...
Analytical study of the acoustic field in a spherical resonator for single bubble sonoluminescence
(Acoustical Society of America Institute of Physics, 2009-09)
The acoustic field in the liquid within a spherical solid shell is calculated. The proposed model takes into account Stoke?s wave equation in the viscous fluid, the membrane theory to describe the solid shell motion and the ...
AcMus: an Open, Integrated Platform for Room Acoustics Research
(Campinas, 2009)
This article describes the design, implementation, and experiences with AcMus, an open and integrated software platform for room acoustics research, which comprises tools for measurement, analysis, and simulation of rooms ...
In-Dressing Acoustic Map by Low-Cost Piezoelectric Transducer
(Ieee-inst Electrical Electronics Engineers Inc, 2020-08-01)
The main difficulty in the grinding process is to identify the correct moment to dress the grinding wheel. Therefore, the cutting tool (grinding wheel) must be monitored. In this context, an innovative technique was developed ...
Caraceterização acústica de salas para prática e ensino musical
(Universidade Federal de Santa MariaBREngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia Civil, 2011-08-25)
The musician needs to properly perceive the sound in rooms where it operates, either in an environment designed to be performed or to studying and practice music. For this, it is necessary that these sites are acoustically ...
Anfis applied to the prediction of surface roughness in grinding of advanced ceramics
(2011-12-01)
This paper introduces a methodology for predicting the surface roughness of advanced ceramics using Adaptive Neuro-Fuzzy Inference System (ANFIS). To this end, a grinding machine was used, equipped with an acoustic emission ...
