Sound insulation tests measure how much noise travels through a seperating wall and/or floor into a neighbouring house - the tests are carried out on newly constructed buildings and test certificates are required by your local Building Control/Standards department before they will accept a completion certificate.

Stewart has  relevant and recognised expertise in acoustics for sound insulation testing - in addition he is a member of the Sound Testing Association - a professional organisation which accredits its members as competent to both test and confirm the results.
