The measurement of the acoustic characteristic of throttling valves, especially in water installation systems, is usually based on air-borne sound presure measurement. With this approach we could not obtain the acoustic parameters which determine the acoustic properties of noise-producing sources.Through direct measurements of fluid-borne noise, i.e. with hydrophones, we can gain better knowledge of the noise-source and transmission characteristics. Because of the influence of the measurement set-up on the noise-source acoustic characteristic, the transfer function of the measurement set-up which forms a closed loop with the source, must be determined. With change of operation conditions and operating parameters, the transfer function changes as well. In this way, the determined noise-source characteristics make it possible for us to involve hydroacoustic models for describing the relation between hydraulic and acoustic conditions.Furthermore,we can also discover the influence of geometric parameters on noise production and emission. We have experimentally analysed the influence of the diameter and length of valve tube on the acoustic characteristic. Through the analysis, we establish the common influence of the chosen geometric parameters on noise production. This relationship is described by a combined geometric parameter, defined as "slimness".
