Supressor Covers

EXO podcast talked about suppressor covers. They don’t like them unless you are shooting more then a few shots which when hunting your not for the most part. I know they used to claim the covers made the suppressor quieter. EXO said they couldn’t tell the difference. Has there ever been a good test on this? I’m suspicious on how much they help with sound reduction
