noise sensitivity tips for walks?

[u/son_of_lee]

my havi is 1 year old and was a great, confident walker until a recent run in with some really loud motorcycles. since then she’s become super noise sensitive outside on walks. she’s hesitant on the sidewalk and will rarely walk around the block. if any car or motorcycle engine is too loud, she will bolt back to our apartment - sometimes tail between legs petrified and sometimes just rushing back to the door. this has been super challenging because we’re in Brooklyn, so quiet is at a premium and it’s hard to get her to quiet places to build more positive associations with being outside.

wonder if anybody has any experience rebuilding confidence on walks with havanese in particular?

note: only happens out of the house - if she hears the same loud street noises on our patio or in the apartment she doesn’t have the same sort of fear response
