Not even sure that this is even related to anything, or even if this is the right forum for this. Here goes. Anyway, went to the Rush concert at the weekend. It was an amazing concert and the bass was so loud, even from where I was sat about half-way back the floor was shaking! But ever since then, I've been feeling light-headed and have also had balance issues, as well as not being able to hear all weekend (which I expected, but seeing as it's Geddy, I don't care). Now I know from the principles of physics that bass sound penetrates further than treble range sound, and I'm wondering if this is the cause of the problem. I don't normally have problems with balance so this is the ONLY thing I can think of which may have caused the problem. Anyone know if this might be the case? I'm already planning to see a doctor in any case.
