Hearing Protection For Shooting | What Actually Works

One shot from a.308 rifle hits 167 dB — loud enough to cause permanent hearing damage in a single exposure. Proper hearing protection for shooting must drop that blast below 140 dB, which is the safety threshold where OSHA says impulse noise stops causing harm. It’s not complicated, but the stakes are high — hearing damage from gunfire is cumulative and permanent.

How Much Noise Reduction Do You Actually Need?

Most gunshots land between 160 and 165 dB at the ear. A 9mm pistol runs about 162 dB, a 5.56 NATO AR-15 hits around 165 dB, and a.308 Winchester reaches 167 dB. Large magnum rounds indoors can push past 170 dB.

Indoor ranges reflect sound off walls and ceilings, making every shot louder than the same round outdoors. That’s why many ranges require or strongly recommend doubled protection. For outdoor shooting with smaller calibers, a good set of electronic muffs with 25+ NRR is usually sufficient.

Your protection needs to knock the blast below that number.

Why The NRR Number Is Misleading

The NRR printed on the box is not the actual decibel reduction you get — real-world protection is roughly half the listed value.

For indoor ranges, that margin gets thin fast. The Audibel hearing protection guidelines for shooting confirm that doubling up is the most reliable way to stay safe in high-noise settings.

The ability to amplify ambient sound while compressing dangerous peaks gives them both safety and situational awareness.

Doubling Up On Hearing Protection For Shooting

Here’s how to do it right:

• Insert foam plugs — Roll the plug into a thin cylinder, pull your ear up and back, and hold it in place until it expands fully.
• Layer over-ear muffs — Place high-quality electronic muffs over the plugs. Electronic models amplify quiet sounds like range commands while compressing gunshots over 82 dB in under 2 milliseconds.
• Check the seal — Shooting glasses often break the muff seal. Look for thin-armed frames or cutouts in the muff padding.
• Take breaks — Step away from the noise for a few minutes during sessions to let your auditory system recover.

When done right, you should hear almost nothing from gunshots — just a quiet thud. Range commands will still be audible through the electronic muffs, which is exactly how it should work. For proven products that hold up at the range, check the best ear protection for shooting range.

The golden rule is simple: if the shot sounds loud through your protection, it’s not enough. Switch to a higher NRR or double up. Your hearing doesn’t heal — once the damage is done, it’s permanent.

FAQs

Can I use regular foam earplugs for shooting?

Yes, but only if they have a sufficient NRR rating.

Do electronic earmuffs work better than passive ones?

Electronic earmuffs let you hear range commands and conversations while still protecting your hearing from gunshots. They compress loud sounds above 82 dB in milliseconds, which passive muffs cannot do — passive muffs simply block all sound equally. For tactical shooting, hunting, or range instruction where communication matters, electronic is clearly the better choice.

Is it safe to double up on hearing protection?

Yes, doubling up with foam plugs under earmuffs is considered the gold standard for indoor ranges and large calibers. Just make sure both layers fit properly and your shooting glasses don’t break the muff seal.
