The microphone on the bike camera doesn't pick up much, but it could register the pointy little bits of hail dinging off the casing, in some casesd after having already dinged off my face on their way down. It can pick up your voice if you shout loudly enough, such as when a twat in a stupid Mitsubishi ute thing passes unnecessarily closely in order to sit two metres further ahead in the slow-moving traffic on Lower Granton Road.
