There are a lot of people using this forum that know more about acoustic HFI, and all other potential types of HFI than the accumulative knowledge of every single person in BAE Systems.
This kind of technology was thought of and discarded years ago, from the work I have been involved in for HFI I seriously hope that this is some kind of early April fools joke, that or just the standard BAE spin on a product looking for a problem (more likely).
