โœฆ Synopsis

SUMMA R Y

A simple method of measuring soundpower is described. Noise is added from a second calibrated source until the room sound pressure lee'el is increased by 3 d B. The noise output of the device is then equal to the added power. A simple loudspeaker, modified to reduce the effect of the environment on the sound power output, is used as the calibrated source of sound power. Checks show that the sound power readings are substantially independent of the room in which they are made.

It is sometimes important to know the sound power radiated from a sound source so that,for example, the solution noise abatement can be carried out on the basis of the sound power radiated. Measurement of the sound power in general is carried out in a reverberant enclosure. This measuring method is

This paper presents calculated and measured sound intensity data describing power flow in near, reflective and refractive acoustic fields. The data illustrate how the intensity vectors can show sources and sinks in an acoustic system and how near and far fields are linked together to form a continuo
