Segura Alcaraz, Jorge Gabriel; Crespo Amorós, José Enrique; Juliá Sanchis, Ernesto; Nadal Gisbert, Antonio Vicente; Gadea Borrell, José Mª (Federación de Asociaciones de Ingenieros Industriales de España (FAIIE), 2014-01)[EN] The present study is conducted to characterize multilayer acoustic panels made from recycled tire rubbers (GTR’s) in order to determine the sound absorption characteristics of these new materials for different ... -
Gilabert Ramón, María Teresa (Universitat Politècnica de València, 2018-11-05)Este trabajo fin de máster consiste en la realización de un estudio numérico mediante elementos finitos sobre sistemas de mitigación sonora del ruido producido por los cohetes espaciales durante la fase de despegue. Este ... -
Atiénzar Navarro, Roberto (Universitat Politècnica de València, 2021-05-17)[ES] En este trabajo de Tesis se han llevado a cabo cuatro líneas de investigación a fin de analizar el comportamiento acústico de nuevas soluciones basadas en tejidos textiles procedentes de la industria textil, a partir ... -
Sánchez-Dehesa Moreno-Cid, José; García Chocano, Víctor Manuel; Torrent Martí, Daniel; Cervera Moreno, Francisco Salvador; Cabrera García, Suitberto; Simon, Francisco (Acoustical Society of America, 2011-03)A systematic study of noise barriers based on sonic crystals made of cylinders that use recycled materials like absorbing component is reported here. The barriers consist of only three rows of perforated metal shells filled ... -
Ramis Soriano, Jaime; Alba Fernández, Jesús; Rey Tormos, Romina María del; Escuder Silla, Eva María; Sanchis Rico, Vicente Jorge (Consejo Superior de Investigaciones Científicas (CSIC), 2010)Acoustic Standards in the building are responsible for, companies and individuals, propose new acoustic materials for the sound isolation. This paper presents a new sound-absorbent material, it is based on natural fibres, ... -
Rey Tormos, Romina María del; Alba Fernández, Jesús; Ramis Soriano, Jaime; Sanchis Rico, Vicente Jorge (Consejo Superior de Investigaciones Científicas (CSIC), 2011)In the building acoustics field usually fibrous materials are used as sound absorbing materials. Nowadays polyester fiber is one of the most used but the pure chip of polyester has a problem. Polyester is obtained of ... -
