摘要：
Various apparatuses and methods for use in determining the density of insulation in a building cavity are provided. The density of the insulation can then be used for determining the R-value of the insulation. An insulation density measuring apparatus includes a sound wave source and a sound detecting device, such as a microphone, for measuring the sound wave attenuation of a sound wave that moves between the sound wave source and the sound detecting device through the insulation. The sound wave attenuation measurement is correlated with an insulation density.
