Acoustic Calculator
The Acoustic Calculator on the Oracle is a cost effective alternative to acoustic labelling and testing schemes. It enables subscribers to the Oracle to quickly calculate the acoustic performance of a range of frame and glazing options and in most cases, with no need for acoustic testing in a laboratory.
Subscribers can then have the calculations verified with a report from an accredited UKAS laboratory such as Build Check Limited.
