Fireworks and baby?

Its victoria day long weekend here in canada so my neighbors have been lighting fireworks alllllll nigbt

My 10 month old is sound asleep and im laying beside him covering his ears with my hands/blankets/whatever i can find, as much as i can😩

I feel like the worst mom ever for not getting some sort of headphones for him, ugh

Im afraid these fireworks will damage his hearing???:(
