Experimental Evaluation of Impulse Noise Isolation by a Light Partition

The transmission of impulse noise between rooms differs significantly from the transmission of constant noise, which is also true for the soundproofing abilities of building structures – in general, impulse noise is isolated much better than constant noise, which was noticed back in the middle of the 20th century. However, today in practical acoustics this circumstance is not given due attention, although a number of studies show this difference. This paper presents the results of measurements of the insulation of impulse noise by a light partition, carried out in modern sound measuring chambers. The results obtained are compared with the measurements carried out according to the standard technique using constant noise.
