This is not a hoax!!! When Marketforce came to me asking to create and record the actual sound certain chemical compounds emitted it blew my mind. It started me off on a quest to investigate do these chemical compounds actually make a unique sound and if so how the hell do I create and capture it. Eventually after much reading and investigating it tuned out they do and I would need the help of a Physicist to make it happen. What you hear in these radio spots is actually what you would hear being emitted from the chemical compounds only pitched down considerably to a frequency range we can actually hear. Mind blowing right.
