I heard that if you wanted to hear SP, you could do so if you had sillicone ear plugs in at the time. Lucky me, my uncle works for a earplug factory. So if anyone in the contidental US wants some, just PM me and I'd be happy to sent a pair to you. But right now, I only have like 20 on me, so it may take a while to get some more. But if you want some, I'm here!
