Calculating the Sound Power of a Dodecahedron Loudspeaker
Calculating sound power helps to quantify the sound radiating from a source. One way to determine sound power uses acoustic intensity. However, the traditional method of calculating acoustic intensity is limited in bandwidth because of spatial sampling. The PAGE method for acoustic intensity has been shown to increase the bandwidth in some situations. To test whether this method improves the calculation of sound power, all sides of a dodecahedron loudspeaker were measured and the intensity was calculated. Multiplying the intensity by the area of the measurement surface yielded the total power. We expect to find that the power spectrum obtained using PAGE is accurate up to higher frequencies than the traditional method. Ultimately, the PAGE method allows for simpler, more accurate measurements with larger microphone spacing.
