文摘

When measuring the acoustic properties of building constructions, a chain generating excitation noise, in which a generator generates the chosen type of noise, is used. White or pink noise is most often utilised. Standard STN ISO 140-4 recommends using white noise, whereas standard STN EN ISO 717-1 recommends pink noise. No reasonable science-based recommendations for the choice of noise are known. This study elucidates the impact of noise on the measurements of acoustic properties of building constructions.
