SILENCIADORS AC\u00daSTICS<\/h3>\n

La p\u00e8rdua d’inserci\u00f3 es mesura en dB. \u00c9s el nivell d’atenuaci\u00f3 real o reducci\u00f3 de soroll del silenciador. La p\u00e8rdua d’inserci\u00f3 es pot restar directament dels nivells de soroll de la font sempre que l’embocadura, apantallat o tancament estigui dissenyat d’acord amb aquesta atenuaci\u00f3.<\/p>\n

Hem de tenir en compte el soroll generat, a causa de l’aire que flueix a trav\u00e9s del silenciador en cada projecte corregint-se en fase de disseny. \u00c9s a dir, l’aire de subministrament ingressa als silenciadors a una velocitat frontal (m\/s) i despr\u00e9s accelera a mesura que passa entre els deflectors del silenciador o el nucli del silenciador circular.
\nAig\u00fces avall (sortida) del silenciador, l’aire s’expandeix.<\/p>\n

L’aire s’accelera i despr\u00e9s s’expandeix. Aquesta expansi\u00f3 provoca soroll generat. Amb un silenciador amb flux d’aire positiu \/ cap endavant \/ de subministrament, obt\u00e9 atenuaci\u00f3 (p\u00e8rdua d’inserci\u00f3) i soroll generat.<\/p>\n

En cada projecte preveurem la p\u00e8rdua de c\u00e0rrega aportada aix\u00ed com tindrem en compte les velocitats d’aire i efectes de turbul\u00e8ncies, optimitzant en cada cas l’atenuaci\u00f3 assolible respectant el rendiment necessari de la instal\u00b7laci\u00f3.[\/vc_column_text][\/vc_column_inner][vc_column_inner width=”1\/2″ css=”.vc_custom_1600769428629{padding-top: 300px !important;padding-bottom: 100% !important;background-image: url(https:\/\/acusticsambient.com\/wp-content\/uploads\/2020\/09\/SILENCIADORES-5.jpg?id=1938) !important;background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;}”][\/vc_column_inner][\/vc_row_inner][vc_row_inner row_type=”row” type=”full_width” text_align=”left” css_animation=””][vc_column_inner width=”1\/2″ css=”.vc_custom_1600769501898{padding-top: 300px !important;padding-bottom: 180% !important;background-image: url(https:\/\/acusticsambient.com\/wp-content\/uploads\/2020\/09\/SILENCIADORES-7-rotated.jpg?id=1940) !important;background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;}”][\/vc_column_inner][vc_column_inner width=”1\/2″][vc_column_text css=”.vc_custom_1604490768331{padding-bottom: 30px !important;padding-left: 30px !important;}”]<\/p>\n

Disseny del comportament aerodin\u00e0mic i ac\u00fastic constant en la totalitat de la cadena de treball.<\/strong><\/h3>\n

P\u00e8rdua de soroll per inserci\u00f3 din\u00e0mica a trav\u00e9s del silenciador. S’expressa en decibels (dB) a cada banda d’octava de freq\u00fc\u00e8ncia (Hz).<\/p>\n

Velocitat frontal: Relaci\u00f3 de la taxa de flux d’aire sobre l’\u00e0rea de la secci\u00f3 transversal del conducte en m2.<\/p>\n

Flanqueig del conducte: el soroll transm\u00e8s en el material d’acer del conducte limita efica\u00e7ment el soroll del silenciador rendiment a 50 dB aproximadament en conductes est\u00e0ndard de xapa met\u00e0l\u00b7lica sense tractar.<\/p>\n

Flux cap endavant: el flux d’aire en el silenciador en la mateixa direcci\u00f3 que la propagaci\u00f3 de soroll.<\/p>\n

Freq\u00fc\u00e8ncia: l’atenuaci\u00f3 de soroll del silenciador s’expressa per a cada una de les 8 bandes de vuitena.<\/p>\n

Caiguda de pressi\u00f3: Del flux de gas a trav\u00e9s del silenciador, en mmca.<\/p>\n

Flux invers: el flux d’aire en el silenciador est\u00e0 en la direcci\u00f3 oposada a la propagaci\u00f3 de soroll.<\/p>\n

El flux invers passa quan l’aire i les ones sonores viatgen en direccions oposades, com en un sistema t\u00edpic d’aire de retorn. En condicions de flux invers, el so es refracta allunyant-se de les parets i cap al centre del silenciador del conducte.<\/p>\n

Self-Noise: soroll generat en el silenciador i causat per la interacci\u00f3 del gas amb el silenciador.
\nS’expressa en pot\u00e8ncia ac\u00fastica en dB i varia amb la velocitat del flux de gas.<\/p>\n

El flux cap endavant passa quan l’aire i les ones sonores viatgen en la mateixa direcci\u00f3, com en un sistema d’aire condicionat o desc\u00e0rrega de ventilador. En condicions de flux directe, el so d’alta freq\u00fc\u00e8ncia es refracta cap a les parets del silenciador del conducte.<\/p>\n
