I didn’t mean to take the Marvel thread off topic by debating with warneral the wisdom of turning up streaming volume (while turning down HA mic input, it turns out). Don has started a thread on OSHA noise levels that I think would be a great place to continue discussion of how to deal with hearing-threatening noise while wearing HA’s - and the first thing that came up in that thread is there is a serious difference between OSHA workplace permissible exposure limits (PEL) and NIOSH “safe” recommended exposure limits (REL).
I still think the best approach to too much outside noise while streaming, if it doesn’t seem dangerous, just annoying, would be just to turn down the HA mic volume (not turn up streaming volume) and if that doesn’t work, plug one’s vents in molds as gr8dane604 has suggested, wear ear muffs or ear plugs over the HA’s, or as Neville suggests, if it’s really bad, just remove the HA’s entirely and don proper ear protection - the max of which is foam ear plugs combined with ear muffs - but I read somewhere that custom-made foam molds work best as ear plugs because of the irregular shapes in ear canals - I wonder how the foam “impressions” that are used to make molds would work?!)
Anyway, I suggest further remarks about combating noise go to Don’s OSHA limits thread or if there is a better, older thread, that thread could be revived to allow the Marvel thread to be more about what a great choice Marvels are as a very premium HA.
