Sorgenti per l'Acustica degli Edifici

Per effettuare misure di acustica degli edifici in conformità con le norme, ad esempio la ISO 140, sono richiesti diversi tipi di sorgenti.

Le sorgenti della Brüel & Kjær sono state ottimizzate per l’acustica degli edifici e comprendono sorgenti sonore omnidirezionali per l’eccitazione degli ambienti e macchine da calpestio per l’eccitazione dei pavimenti.
