This paper investigates the sound insulation properties of clay hollow brick walls with low void fraction, horizontal/vertical mortar joint and plaster finishing. Methods based on homogeneous walls (Sharp theory and ISO 12354 procedure) are evaluated. A reference curve obtained as the mean of normalised sound reduction index curves measured in laboratory on real brick walls is proposed and its suitability for sound insulation estimations is discussed.

Abstract
This paper investigates the sound insulation properties of clay hollow brick walls with low void fraction, horizontal/vertical mortar joint and plaster finishing. Methods based on homogeneous walls (Sharp theory and ISO 12354 procedure) are evaluated. A reference curve obtained as the mean of normalised sound reduction index curves measured in laboratory on real brick walls is proposed and its suitability for sound insulation estimations is discussed.File in questo prodotto:
