Resumen

The international standard ISO 16283-3: 2016 provides procedures to determine the airborne sound insulation of building facades, both for whole facades (global methods) and for facade elements (element methods), such as for doors, windows, etc. In both cases, the standard offers the possibility of using environmental noise as the sound source (road traffic noise, railway noise and aircraft noise) or, alternatively, a loudspeaker that emits broadband noise as an artificial sound source. When using an artificial sound source, the loudspeaker directivity requirements have been established to ensure uniform sound coverage across the facade area. This work analyzes the distribution of sound pressure level on the facades for the types of loudspeakers most commonly used in acoustic testing from a statistical point of view. This study has been carried out for both free field conditions, which is the condition specified for the qualification of loudspeaker directivity by the international standard, and actual conditions (i.e., "in situ" measurements). The purpose of the study is to determine the extent the speaker directivity requirement of the ISO 16283-3 standard guarantees correct sound coverage of facades under "in situ" measurement conditions. Finally, practical conclusions on loudspeaker choice have been derived, based on the behavior of the different types of loudspeakers applied to this type of measurement.
