Brighton – Sound Testing & SAP Calculations

THE BRIEF

  • To pass Airborne tests, you must score 43db (45db for new builds) or higher
  • Airborne tests measure the difference in sound levels between the receiver room and neighbouring walls or floors
  • If the sound output in the receiver room is 100db and the sound leakage being passed through into the neighbouring room is 40db, then the result would be 60 and therefore would be a pass
  • To pass Impact tests, you must score 64db (62db for new builds) or lower
  • Impact tests measure how effectively the Sound Insulation between floors cancels out sound. If there is less than 62 decibels of sound leaking through into below floors then these tests would be a pass

THE PROCESS

  • After reviewing drawings, on site testing was ready to be completed. All calibrated equipment was setup in accordance to our strict procedures to ensure the most accurate result possible

  • Compliant
  • The Proposed Dwelling is more efficient than the Notional Dwelling and therefore compliant with regulations
  • We achieved a Water Efficiency Rate of 109.65 Litres per person per day, the Target being ≤ 110L 
  • All of the Ventilation Tests passed with no problems   
  • Our Combined Testing and Certification package offers excellent value
