Orange trees improve acoustic insulation.

A new method for creating acoustic insulation uses fibers from orange tree pruning, creating a product that provides 150% more noise control than conventional gypsum boards. The researchers from the Universitat Politecnica de Valencia and the Universitat de Girona used polypropylene, a common plastic, in addition to the orange tree fibers to develop the new insulation material.

Published in the Journal of Construction and Building Materials, the research shows that the design provides an acoustic insulation potential of about 29 dBA, while gypsum boards typically provide around 27 dBA. The researchers note that by using a double solution material, one that incorporates two boards and an absorbent wool in between, the improvement over gypsum could be as high as 5 to 6 dBA, more than double the single layer design.
