On Site Sound Testing & Reporting

These tests are more commonly known and referred to as SI tests. They are one of the same procedure and assessment that has been introduced in order to evaluate and check the validity of a partitioning structure separating two adjoining residential developments. The requirements for this sound testing refer to either new build constructions or refurbished developments.

Sound testing is carried out at your development usually within 5-10 days from the initial enquiry and the reports are submitted to you in report format 5-7 days later and come complete with individual data sheets. Multiple sound testing reports are issued to allow you to pass on copies to the relevant parties.

Our sound testing procedures are carried out in accordance with current standards ISO 140-4 'Field Measurement of Airborne Sound Insulation Between Rooms' and ISO 140-7 'Field Measurement of Impact Sound Insulation of Floors.' The results are rated in accordance with ISO 717-1 and ISO 717-2. These results are then assessed generally in accordance with the 2010 Building Regulations Document E 'Resistance to the Passage of Sound' in order to indicate compliance.

For purpose built dwellings or dwellings formed by material change of use, the Building Regulations Approved Document E 2003 'Resistance to the Passage of Sound' requires separating structures to adhere to the following requirements as detailed in Table 1a of the below document.
