Acoustic Calculator
The Acoustic Calculator on the Oracle is a cost effective way of getting acoustic performance values for your windows up to 38 dB. It enables subscribers to the Oracle to quickly calculate the acoustic performance of a range of window frames 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 notified body such as Build Check Limited which is acceptable for UKCA Marking.
