Hello so my apartment complex is having a drill next week and I asked if I could help set them off and they said yes and I’m going to do it. But I have sound to sensory issues and was wondering if these earmuffs would be sufficient for dealing with 6 simplex 4903s in the building going off all close proximity to each other in the building. Anyways these are the brand of earbuds but not sure what they are rated for noise dcb thanks. Yes I don’t like loud noises but I have an interest in fire alarms. Plus after the drill I will be getting a simplex 4903 
Pretty sure those are called “headphones”, & given they’re similar to a pair I use I’m sure they’ll be more than adequate for your application.
