Airborne sound transmission loss characteristics of wood-frame construction
(USDA Forest Service. Forest Products Laboratory, 2018)
Determinação experimental e numérica da redução sonora aérea em paredes de alvenaria utilizadas em habitações
(Universidade Federal de Santa MariaBREngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia Civil, 2011-03-15)
In this research some kinds of masonry walls have been used as internal divisions in
three Brazilian dwelling buildings to determine the airborne sound reduction, by
experimental tests in field and computer simulations. ...
The sound field generated by tethered stingless bees (Melipona scutellaris): inferences on its potential as a recruitment mechanism inside the hive
(COMPANY OF BIOLOGISTS LTD, 2008)
In stingless bees, recruitment of hive bees to food sources involves thoracic vibrations by foragers during trophallaxis. The temporal pattern of these vibrations correlates with the sugar concentration of the collected ...
Avaliação de ferramenta de simulação da transmissão sonora para projetos de isolamento acústico em edificações habitacionais
(Universidade Federal de Santa MariaBREngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia Civil, 2014-07-19)
In July, 2013, Brazil s new standard, NBR15575:2013, began to require minimum
thermal, luminal, structural and acoustical performance levels in new constructions of
residential dwellings. Thus, computer programs that ...
Comparison between sound insulation prediction models for airborne noise transmission
(IngenieriasIngeniería de SonidoBogotá, 2017-07)
El objetivo principal de este proyecto es analizar y comparar el comportamiento del aislamiento acústico
alrededor del rango de la frecuencia critica con diferentes modelos. Esto se hace con el fin de hallar un modelo ...
Comparison between sound insulation prediction models for airborne noise transmission
(IngenieriasIngeniería de SonidoBogotá, 2019)
Auralización del sonido transmitido por vía aérea a través de dos adecuaciones diferentes para un tabique simple, considerando distintas locaciones de oyente
(IngenieriasIngeniería de SonidoMedellín, 2019)
Análise comparativa do isolamento acústico em diferentes geometrias: Ensaios em campo e simulações computacionais
(Universidade do Vale do Rio dos Sinos, 2018-10-09)
Currently in Brazil, building companies need to design and construct residential buildings with a minimum of acoustic insulation conditions, and to this end, the acoustic characteristics of the constructive system must be ...
Thoracic vibrations in stingless bees (Melipona seminigra): resonances of the thorax influence vibrations associated with flight but not those associated with sound production
(COMPANY OF BIOLOGISTS LTD, 2008)
Bees generate thoracic vibrations with their indirect flight muscles in various behavioural contexts. The main frequency component of non-flight vibrations, during which the wings are usually folded over the abdomen, is ...
