Estudo de cortinas black-out como componentes no isolamento sonoro de fachadas
(Universidade Federal de Santa MariaBREngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia Civil, 2008-10-24)
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 ...
On synchrophasing control of vibration and sound radiation for a floating raft vibration isolation system
(2014-01-01)
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 ...
Estudo e desenvolvimento de uma fonte sonora com direcionamento controlado, voltado para exames de audiometria
(Universidade Estadual Paulista (Unesp), 2017-06-23)
O presente trabalho trata do estudo de uma fonte acústica com direcionamento sonoro controlado. A proposta envolve o desenvolvimento do projeto de um equipamento de teste para uso biomédico na aplicação e análises ...

A non-linear stiffness experimental device for shock isolation
(2013-01-01)
Shock vibration is a common problem involving large forces and accelerations, usually resulting in non linear behavior. Normally shock isolation systems are modeled eith linear passive stiffness elements intended to absorb ...

An investigation of a two-stage nonlinear vibration isolation system
(2013-03-18)
This paper investigates the most desirable configuration of a two-stage nonlinear vibration isolation system, in which the isolators contain hardening geometric stiffness nonlinearity and linear viscous damping. The force ...

Variation among vocalizations of Taraba major (Aves: Thamnophilidae) subspecies
(Taylor & Francis Ltd, 2018-01-01)
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 ...
