Which materials are best for ear defenders?

The head-band and outer covering is usually made from a hard thermoplastic or metal. The protection usually comes from acoustic foam – this absorbs sound waves by increasing air resistance, thus reducing the amplitude of the waves. Ear defenders can be carried on a head-band or clipped onto the sides of a hard hat.

Are foam ear plugs safe for shooting?

“For louder firearms or indoor or covered shooting situations, Howard Leight’s Impact PRO electronic earmuff (NRR 30) or foam earplugs (up to NRR 33) are the smart choices.” Doubling up—the practice of wearing both foam earplugs along with earmuffs—is a viable option as well.

What should I look for in shooting ear protection?

Ear protection for shooting should have an NRR of 30 or better. Most ear protection will max out at NRR 34, so the best bet is to get earmuffs AND plugs at that rating. Electronic earmuffs can work very well, so they should certainly be considered. Many models will automatically attenuate noise of 85 dB or more.
