"In any case, I just found something better to do than watching my colleagues. I'll do some research on the findings of that archeological team you told me about, it might be helpful."
Joe left and headed for his room, the console with access to the corporate network should suffice for his research.

He got to his room without incident, the console started and connected without issue, but when he was about to type his search query Joe noticed he had forgotten to ask for the name of the archeologists, where the facility in question was located, or for that matter anything that would point at a source. However Joe also didn't want to walk back, interrupt James, and ask for that information, she was busy already. In addition he would likely encounter her again, and an archeological site doesn't just run away.

Thus Joe decided to just search for the vague topic, and didn't find anything too useful for his research, what a failure that was. Most of what he did find was a bunch of scam sites on how to quickly increase one's synch rate; great, just great.
Still, among the hundreds of scams and uninteresting unrelated results, he did find one old archive. It didn’t contain what he was looking for, but he did stumble upon an article about what at the time of writing was called a 'sound cannon' by some, while others just called it plainly long range acoustic device.
Intrigued by the concept he decided to search the market for one, but to his disappointment, the market for NC parts contained nothing but the usual weapons.
Despite that he still found something, although it was on the normal electronics market: High powered speakers for 500 credits per speaker, with fitting control circuits for 1000 credits each.

After looking at his balance, he decided to purchase 2 control circuits and 200 speakers for 102000(2*1000+200*500) credits, about a third of his balance. In hindsight Joe felt sorry for the poor guy accepting parcels, he would have a hard time in a few days.
