Effect of Systematic Errors on Building Component Sound Insulation Measurements Using Near-Field Acoustic Holography

Effect of Systematic Errors on Building Component Sound Insulation Measurements Using Near-Field Acoustic Holography

Near-field acoustic holography (NAH) provides an effective way to achieve wide-band, high-resolution visualization measurement of the sound insulation performance of building components. However, based on Green’s function, the microphone array’s inherent amplitude and phase mismatch errors will expo...
