The earplugs each measure just 25 x19 mm (0.9 a 0.7 in) and weigh throughout at 3.8 g (0.1 oz), with the aim of being comfortably worn. The company says the earplugs are actually ergonomically designed to fit comfortably and tightly inside wearer’s ear. That tight fit could help to cut the number of noise that the user hears through closing off the ear (passive sounds reduction). The active noise cancellation however, is where things get interesting.
Noise cancelling technology, which is widely employed in headphones, lets users drown out background distractions to listen for their music better. But what should you not want to hear anything at most? Standard earplugs often don’t cut it (or bring inconveniences with their own), so the new earplugs employ active noise cancelling (sans music) to decrease what users can hear.
The tecnología de cancelación de ruido aren’t really the only noise cancelling earplugs available (there’s Pro Sounds X-Pro earplugs, which in turn passively cancel different noise using valves, along with Hush earplugs, which combine passive cancellation using white noise or nature scenes). But Noise Cancelling Tecnologia differentiates itself by making use of active noise cancelling tech similar about what you’d find in some consumer earbuds.
Comparable to noise cancelling ohrstöpsel, earplugs each have a smaller microphone that captures ambient sound that the wearer would otherwise be can hear. Using speakers, they then produce a noise-cancelling wave that’s 180-degrees beyond phase with the original sound – this can be a hallmark of all ANC, a process introduced rice by Bose.
