Abstract

Il comfort acustico nei luoghi di lavoro, quali gli uffici, garantisce il benessere dei lavoratori, migliorando la concentrazione e la produttività. Norme recenti come la ISO 22955:2021 e protocolli volontari come la certificazione WELL (WELL V2 - Sound) offrono linee guida per raggiungere il comfort acustico attraverso una corretta progettazione dell’ambiente. Le sfide sorgono soprattutto in ambienti con vincoli architettonici durante i lavori di ristrutturazione. L'analisi preliminare prevede la configurazione degli ambienti in base agli standard, alla letteratura, e in ultimo da casi di studio in situ di uffici open plan esistenti. Gli ambienti considerati sono privi di arredi e il trattamento acustico è limitato ai controsoffitti, in conformità alla norma ISO 22955:2021. I parametri includono la valutazione dell'effetto Lombard - l'aumento involontario dello sforzo vocale del parlatore in presenza di elevato rumore ambientale - per garantire il comfort acustico negli uffici open plan. L’intero studio è volto ad analizzare la sinergia tra standard normativi (ISO) e protocolli volontari (WELL) al fine di individuare compatibilità nell’applicazione di entrambi i documenti.
