It's very interesting to have a chapter about sound in a fucking manga. Then you must imagine them yourself, and both sound and silence are twice as true as they are personal. My favourite one up until now.
@Alraisen you'll probably have watched it by now, but this scene is in episode 5 of the anime at the end, you can also just search on youtube "girls last tour sound of rain", it is one of my favorite anime scenes in general
