“Do they completely block out all noise, or do they allow some ambient sound to pass through?”

1-1 of 1 Answer

• The Westone TRU WR20 Universal Earplugs provide 20dB and NRR 12 average attenuation, which means they reduce mid-level noise exposure. They are designed to ensure comfortable listening levels at concerts, clubs, sporting events, and during air travel, suggesting that they allow some ambient sound to pass through rather than completely blocking out all noise.
