A state-space modeling approach for active structural acoustic control
(IOS PRESS, 2009)
The demands for improvement in sound quality and reduction of noise generated by vehicles are constantly increasing, as well as the penalties for space and weight of the control solutions. A promising approach to cope with ...
Evaluating acoustic indices in the Valdivian rainforest, a biodiversity hotspot in South America
(Elsevier B.V., 2019)
Passive acoustic monitoring is becoming an extensively used tool to evaluate the status and variation of populations of sound producing animals. The analyses of extensive acoustic recordings for identification and detection ...
Energetic analysis of an actively controlled one-dimensional acoustic waveguide
(Elsevier Sci LtdOxfordInglaterra, 2003)
A model for three-dimensional simulation of acoustic emissions from rotating machine vibration
(Acoustical Soc Amer Amer Inst PhysicsMelvilleEUA, 2010)
An indirect hybrid sound transmission loss controller

Calling sites and acoustic partitioning in species of the Hyla nana and rubicundula groups (Anura, Hylidae)
We analysed spatial and acoustic partitioning among four species of Hyla belonging to two species-groups: nana (H. nana and H. sanborni) and rubicundula (H. elianeae and H. jimi). Field activities were conducted at three ...
Velar activity in individuals with velopharyngeal insufficiency assessed by acoustic rhinometry
(Faculdade de Odontologia de Bauru - USPBauru, 2014-07)
Acoustic rhinometry is routinely used for the evaluation of nasal patency. Objective: To investigate whether the technique is able to identify the impairment of velopharyngeal (VP) activity in individuals with clinical ...
Piezoelectric composite film for acoustic emission detection
The continuous technological advances require materials with properties that conventional material cannot display. Material property combinations are being the focus to the development of composite materials, which are ...
Visual and acoustic communication in the Brazilian torrent frog, Hylodes asper (Anura : Leptodactylidae)
(Herpetologists League, 1999-09-01)
We studied the signaling, territorial, and courtship behaviors of the diurnal frog Hylodes asper. Visual and acoustic communication were used during intraspecific interactions involving males, females. and subadults. Hylodes ...
