FAQs

What do the NRR numbers mean? SensGard has 26 and 31.

The Noise Reduction Rating (NRR) is a standardized way to compare how effectively different hearing protection devices reduce sound. A higher NRR indicates greater noise reduction.

Because NRR values are measured in decibels—a logarithmic scale—every 10 dB represents a doubling of sound reduction. That means an NRR 31 device provides roughly twice the noise‑reducing power of an NRR 21 device.

How do I know what number or NRR rating I need?

Choosing your NRR is simple—match it to your noise level and comfort needs.

  • For everyday loud environments like lawn equipment, power tools, concerts, or busy spaces, NRR 26 delivers strong, comfortable protection.

  • For high‑intensity noise such as chainsaws, jackhammers, firearms, or heavy construction, NRR 31 gives you maximum protection.

  • If you want the highest level of defense—especially if you already have some hearing loss—NRR 31 is the smarter choice.

Higher NRR typically means more advanced protection, so pricing may vary accordingly.

Is SensGard an ear plug or an ear muff?

Neither. SensGard represents a third category of hearing protection with a completely different approach.

Ear plugs work by filling the ear canal and physically blocking sound. To be effective, they must be inserted deeply and correctly—something many users struggle with.

Ear muffs create a seal around the entire ear. The headband pressure keeps the cushions tight against the head, but that seal is easily compromised by glasses, safety eyewear, facial hair, or movement, which reduces their effectiveness.

SensGard works differently. It seals at the entrance of the ear canal and uses acoustic chambers to redirect and dissipate sound energy before it reaches the ear. These chambers are precisely tuned to reduce harmful noise while still allowing safe‑level sound to pass through, giving you protection without isolation.
