The Sonocat can measure the sound intensity level and direction in 3D. This can be used to determine the location of sound sources, for example. It is not always obvious where the sound is coming from or which source has the highest contribution to the noise.

Applying the theory of sound propagation around a rigid sphere enables the SonoCat to account for the most dominant scattering that impacts the measurements. It is therefore possible to estimate the 3D sound intensity vector and sound pressure level as if the SonoCat was not in the field.
