Methods & Personnel
Charlie Fleming carries out most of this work himself. He does so using a mixture of over 20 year’s experience, and knowledge of what will work, together with calculations using standard acoustical equations.

Most of these equations have been incorporated into spreadsheets he has developed for calculating sound transmission through walls and floors in buildings, from inside to outside buildings and vice versa, reverberation times (acoustic quality), ductborne fan, regenerated noise and crosstalk in ductwork systems.
