I am wondering how important it is to protect your hearing under different circumstances of blasting.
When are my ears possible damaged? For example once I sat of 400g of ANNM and was 45 m away without ear protection, was it dangerous?(Ifelt no pain afterwards or even directly when the shockwave hit, what I can rembember)
An other time I hit a small ammount of AP with an hammer BANG, a high frequenzy ringing in my ears for some minutes, I hadnīt expected it to be that loud, here it is of course good to wear protections, but how dangerous was it?) Three times when I detonated a wery powerfull mix of Ap/mg/kcl04 (filmcanisters) from 15-25m away I really felt it in my ears, but it didnīt thurt afterwards, just when the soundwaves hit. How damaging was this, for example compared with the ANNM explosion I metioned.
I also want to know if you use to wear earprotections, and when you find it necessary. Is the common earplugs ok, or do I need something more sometimes( that sorts higher frequenzies out)?
I also hope that this is in the right section and that it is going to be a good topic.
