So, I guess it’s time to go in. I need to Shop-Vac the unit because it’s full of metal shards from the cutting. Also, I’ll need to put a ThermaRest on the bottom of the inside. A flashlight, an assistant, and a few minutes of quiet and I should know if I’ve blocked The Hum. If not, I’ll follow up with some outside and inside readings on the VLF spectrum. My portable VLF unit is not reliable, and I’m quickly searching out an affordable alternative. My only concern is that the Box is not yet on a trailer, and it is sitting in an garage on the Sunshine Coast of BC. Because of all the outdoor sounds that transmit through the side lattice of the garage, the ambient noise level may be too high the hear the Hum. So I’ll need to gather funds for a trailer, which can then be taken anywhere for testing.
But I work full time (more than full time actually), and I want to have a life, so I will do it soon.
