Sound Insulation Testing – Leicester LE3

THE BRIEF

  • We were instructed to complete Sound Insulation Tests on this change of use building which was previously classed as a villa, but has now been skilfully divided into three self contained flats
  • These tests consisted of a mixture of Airborne Floor and Impact Floor tests
  • To pass an Airborne test, you must score 43db or higher (45 on new build properties)
  • 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 an Impact test, you must score 64db or lower (62 on new build properties)
  • Impact tests measure how effectively the Sound Insulation between floors cancels out sound. If there is less than 64 decibels of sound leaking through into below floors then the test would be a pass

THE PROCESS

  • After reviewing drawings, on site testing was ready to be completed. All suitable equipment was set up and checked over to ensure the best possible result
