Hamilton Buhl HG26 NoiseOff Ear Plugs 26 dB

What the NoiseOff ear plugs are

Hamilton Buhl HG26 NoiseOff ear plugs are passive hearing protectors that use patented, battery-free technology to reduce ambient noise. They are designed for students, office workers and travellers who need to concentrate in loud surroundings without losing the ability to hear speech clearly. The adjustable headband and lightweight build suit extended wear during study, reading or focused work sessions.

Practical limits of the 26 dB rating

The Noise Reduction Rating of 26 decibels applies to steady broadband noise under laboratory conditions; real-world attenuation varies with fit, headband tension and the frequency content of the sound. Sudden impulse noises and very low-frequency rumble are reduced less effectively than the single-number rating suggests. The device does not amplify or process audio, so it cannot compensate for poorly fitting ear cups or seal leaks.

What to check before ordering

Verify that an over-the-head band with ear cups is comfortable for your head size and that you can tolerate the clamping force required for a proper seal. Confirm that the black colour option matches your preference, as the product is supplied in this single finish. Ensure you do not require active noise cancellation, Bluetooth connectivity or a higher certified attenuation value for regulated occupational use.
