Effective noise reduction of 2 ear muffs?

Author: admin Category: Noise Reduction

I have 2 ear muffs. One is in-the-ear type and the other is external(over the ear.) The in-ear muff has a noise reduction rating of 21db. The external ear muff has a rating of 30db. If I wear both, what is the effective noise reduction?
