                            HACSensor

This sensor performs Hearing Aid Compatibility testing on a region in space. HAC testing requires data gathered on a 5cm by 5cm arbitrarily oriented rectangle in freespace. The point is to determine if e.g. a cellphone will generate E and H fields large enough to interfere with a hearing aid, modulo the wearer's ability to adjust the position of the phone to a better location.
