Just had a brilliant game in part thanks to Syrinscape. Characters were deafened from an explosion from end of the last time we met and we started this game off with a high resonance tone mixed with lots of underwater voices and noises to simulate deafness and then once hearing finally restored after several minutes switches it to the sound of screaming, crying, burning, and alarm bells very loud.
Really added to the immersion for this sort of thing a LOT!
