LA BASSA RUMOROSITA' E' DA SEMPRE UNA QUALITA' APPREZZATA PER OGNI TIPO DI ELETTRODOMESTICO, SEBBENE IL MIGLIORAMENTO TECNOLOGICO NEL SETTORE SI CONCENTRA SU ASPETTI LEGATI AL RISPARMIO ENERGETICO E AL BASSO IMPATTO AMBIENTALE DEI MATERIALI. UNO DEI LIMITI PER LO STUDIO DI SOLUZIONI ACUSTICHE APPLICATE AI PICCOLI ELETTRODOMESTICI, E' LA COMPATTEZZA DEGLI STESSI: LE AZIENDE PRODUTTRICI TENDONO A REALIZZARE OGGETTI CON IL MINIMO INGOMBRO POSSIBILE, RENDENDO DIFFICILE L - INSERIMENTO DI MATERIALI AGGIUNTIVI FINALIZZATI AL CONTENIMENTO DEL RUMORE. L - OBIETTIVO DEL PROGETTO E' QUELLO DI SVILUPPARE UN MATERIALE FONOASSORBENTE EFFICACE MA DALLE DIMENSIONI RIDOTTE. L - INNOVAZIONE ACUSTICA OGGETTO DI RICERCA INDUSTRIALE CONSISTE NELLO STUDIO DI SISTEMI DI ASSORBIMENTO INEDITI: I "METAMATERIALI". ESSI COSTITUISCONO UN - EVOLUZIONE DEI "RISONATORI DI HELMOLTZ",DIFFERENZIANDOSENE PER DUE MOTIVI: 1) SELETTIVITA': I "METAMATERIALI" OPPORTUNAMENTE PROGETTATI, SONO CAPACI DI SVILUPPARE UN FONOASSOR (Italian)

LOW NOISE HAS ALWAYS BEEN A QUALITY APPRECIATED FOR ANY TYPE OF HOUSEHOLD APPLIANCE, ALTHOUGH THE TECHNOLOGICAL IMPROVEMENT IN THE SECTOR FOCUSES ON ASPECTS RELATED TO ENERGY SAVING AND THE LOW ENVIRONMENTAL IMPACT OF MATERIALS. ONE OF THE LIMITS FOR THE STUDY OF ACOUSTIC SOLUTIONS APPLIED TO SMALL APPLIANCES, IS THE COMPACTNESS OF THE SAME: MANUFACTURERS TEND TO CREATE OBJECTS WITH THE LEAST POSSIBLE FOOTPRINT, MAKING IT DIFFICULT TO INSERT ADDITIONAL MATERIALS AIMED AT REDUCING NOISE. L — THE OBJECTIVE OF THE PROJECT IS TO DEVELOP AN EFFECTIVE BUT SMALL SOUND-ABSORBING MATERIAL. L — ACOUSTIC INNOVATION SUBJECT TO INDUSTRIAL RESEARCH CONSISTS OF THE STUDY OF NEW ABSORPTION SYSTEMS: ‘METAMATERIALS’. THEY CONSTITUTE AN EVOLUTION OF THE HELMOLTZ ‘RESONATORS’, DIFFERENTIATING THEMSELVES FOR TWO REASONS: 1) SELECTIVITY: THE APPROPRIATELY DESIGNED “METAMATERIALS” ARE CAPABLE OF DEVELOPING A FONOASSOR (English)

LE FAIBLE BRUIT A TOUJOURS ÉTÉ UNE QUALITÉ APPRÉCIÉE POUR TOUT TYPE D’APPAREIL MÉNAGER, BIEN QUE L’AMÉLIORATION TECHNOLOGIQUE DANS LE SECTEUR SE CONCENTRE SUR DES ASPECTS LIÉS AUX ÉCONOMIES D’ÉNERGIE ET À LA FAIBLE INCIDENCE ENVIRONNEMENTALE DES MATÉRIAUX. L’UNE DES LIMITES POUR L’ÉTUDE DES SOLUTIONS ACOUSTIQUES APPLIQUÉES AUX PETITS APPAREILS, EST LA COMPACITÉ DE LA MÊME: LES FABRICANTS ONT TENDANCE À CRÉER DES OBJETS AYANT LE MOINS D’EMPREINTE POSSIBLE, CE QUI REND DIFFICILE L’INSERTION DE MATÉRIAUX SUPPLÉMENTAIRES VISANT À RÉDUIRE LE BRUIT. L — L’OBJECTIF DU PROJET EST DE DÉVELOPPER UN MATÉRIAU D’ABSORPTION SONORE EFFICACE MAIS DE PETITE TAILLE. L — L’INNOVATION ACOUSTIQUE SOUMISE À LA RECHERCHE INDUSTRIELLE CONSISTE EN L’ÉTUDE DE NOUVEAUX SYSTÈMES D’ABSORPTION: «MÉTAMATÉRIAUX». ILS CONSTITUENT UNE ÉVOLUTION DES «RÉSONATEURS» HELMOLTZ, SE DIFFÉRENCIANT POUR DEUX RAISONS: 1) SÉLECTIVITÉ: LES «MÉTAMATÉRIAUX» CORRECTEMENT CONÇUS SONT CAPABLES DE DÉVELOPPER UN FONOASSOR (French)
