Abstract
Airborne sound insulation in situ tests were done for a roof prototype made with light and green material such as a coconut fiber substrate of 17 cm thickness in dry and humid conditions. Levels of background noise, sound pressure levels, and reverberation time in bands of 1/3 octave were measured in order to calculate the difference of the apparent level and apparent sound reduction index, as well as the prototype’s global values that characterize insulation of materials. It was observed that sound insulation in dry conditions is higher than in humid conditions, yielding 44 dB and 41 dB respectively.
