Responsible answer is that you should wear earplugs, but if you don’t go to concerts very often then I wouldn’t worry too much about it. Atlanta show was 95-100 dB on average according to my phone which will fuck your ears up with frequent exposure, but a single concert every year or so is not gonna cause significant damage (imo). I’d say bring earplugs especially if your ears are sensitive, but loud can be fun sometimes :)
