Acústica Integral has installed Acustiart 50 type absorbent acoustic elements on the ceiling of a school’s dining facilities in order to increase the absorption of the existing ceiling.
According to the current regulations based on the DB-HR of the Technical Building Code a reverberation time of 0.9 seconds is recommended for empty dining rooms.
As the reverberation value is above that recommended, corrective measures to control the current reverberation time and be able to adjust it appropriately to the recommended value are required. We must also note that this canteen already has an accessible absorbent acoustic ceiling of 600x600mm which is insufficient to meet the objective criterion of the DB-HR building code (CTE).
The following graph shows the measurements taken before and after installing the ACUSTIART Acoustic Islands, which allows achieving a reverberation time below the recommended value:
The result obtained after installing the ACUSTIART absorbent panels is a reverberation time in the canteen of 0.82, which is a value lower than the limit established by the DB-HR Building Code (CTE).
Therefore, the values recommended by the Technical Building Code are achieved with the treatments conducted with Acustiart 50 Acoustic Islands, and in addition, they confer a highly positive subjective feeling to the final user. Another of the advantages of the Acustiart 50 products, is that the customer could maintain the existing installation and the impact of the installation of the Acustiart 50 products was minimum in the daily use of the canteen.
