Abstract

In many applications of noise control engineering, knowledge about the sound-absorbing properties of acoustically reacting surfaces is essential. Being able to measure sound absorption of surfaces in-situ, i.e. at the site but also for the actual sound source, would prove very useful for this reason and would eliminate the need for laboratory measurements. This paper will present a (patented) new method for the in-situ measurement of sound absorption. This method is particularly useful since the sound absorption can be determined without a priori knowledge about the actual sound field present near the structure under investigation. In the paper the theory behind the method will be described and some experimental results will be shown.
