Abstract: When designing loudspeakers, a number of parameters have to be known. The total radiated sound power is one of these measures. Typically performed in anechoic conditions a large number of measurements are needed for this estimation. It is of interest to know how accurate this estimation is related to the actual radiated power. Two coherent point sound sources separated by 30 cm are simulated in three scenarios. The sound pressure is calculated over discrete points at a distance around a sphere covering the two point sources. The error between estimated and analytical sound power solution is computed. A number of different microphone arrangements are tested. Results suggest that spatial distribution over the sphere and the number of measurements is critical.
