How effective are sound isolating earmuffs? What should I pay attention to when buying?

The effect of soundproof earmuffs depends on the sound insulation value, generally you can look at the NRR coefficient, the higher the NRR, the better the sound insulation performance. And this effect is determined by the sound insulation method: active noise reduction and passive noise reduction.

Passive noise reduction is to directly use the soundproof material in the earcup for sound insulation, generally using soundproof cotton. Active noise cancellation is to add a device in the earcup, which emits a reverse sound wave at the same time when receiving external noise waves, and two positive and negative opposite sound waves will cancel out to achieve the effect of noise reduction. Then there is a kind of electronic noise reduction earmuffs with a pickup function, generally known as tactical earmuffs, sports shooting earmuffs, don't look at the words and looks like they are only used in wooden warehouses, and many workers on the construction site can actually use them.

For example, long-term work on the construction site will be disturbed by noise for a long time, and the hearing will be very damaged; Wearing earmuffs can be effective in reducing noise, but if there is danger on the construction site, the pickup function will work: it will transmit the shouting of others to you, the warning sound from outside, and let you hear it clearly, so that you can reduce the noise at work and see all directions.

As for the purchase precautions: depending on the environment you need to use, choose general earmuffs or pickup earmuffs, active noise cancellation is generally thousands, not affordable. Comfort, some cottage earmuffs may have sound insulation performance, but there will be problems such as too tight chucks, poor materials, etc., in this regard, it is best to search for other people's use evaluation, or have physical stores to try it on the spot.

Whether to support the replacement of accessories, such as soundproof cotton is needed to be replaced regularly, can not expect a piece of cotton to be used for five or six years and the effect is consistent, and the size of the soundproof cotton used without ear cups is also different, so it is best to bring your own accessories** (DIY high play look at another look).

How to wear helmet-style earmuffs: Insert the inserts on the earmuffs into the standard accessory slots on the helmet and fix them in the correct position.
