The extent that may lead to hearing loss — when extended, he says — is decrease, at 85 dB.
“These spikes are normally transient,” Cushing provides, referencing these motion scenes, “but when they exceed 120 dB, even brief bursts could be unsafe. … At ranges above 100 dB, injury can happen in as little as quarter-hour.”
“That may be as loud as a live performance,” Sarah Lundstrom, an audiologist at HearCare Audiology, fellow of the American Academy of Audiology and member of the American Board of Audiology, tells Yahoo Life. “The louder the sound, the much less time it takes to wreck your listening to.”

Lundstrom recommends additionally sporting them when working with noisy gear, reminiscent of a lawnmower or energy instruments.
Whereas the plugs will restrict noise, they don’t fully block it out. “Filtered earplugs, whether or not they’re OTC or customized, permit sound to stay clear however at a quieter stage — in different phrases, they don’t distort the standard of the sound,” Cushing clarifies.
