Which type of earplug provides the highest level of attenuation?
NRR Ratings The highest NRR rating for earplugs is 33, and the highest available NRR rating for earmuffs is 31. These values reflect the level of noise protection available for each device when worn alone. Combining earplugs with earmuffs can offer a NRR protection level of 36.
What is attenuation earplugs?
In hearing protectors, flat attenuation is achieved by re-introducing a resonant peak in the earplug response to simulate that of the average normal open ear. Combined with a moderate amount of sound reduction, a flat-attenuation earplug preserves the tonal balance of music and the clarity of speech.

Do earplugs block out all sound?
Unfortunately, earplugs or earmuffs that block out all noise don’t exist. They cannot exist because of bone conduction: noise doesn’t only reach our cochlea via the ear, but also through the skull.
Is NRR 32 good?
A hearing protector with an NRR below 20 will in general protect less than a device with an NRR in the 20’s. A device with an NRR in the high 20’s or low 30’s will generally offer the most protection you can buy.
How many dB do foam earplugs reduce?

What are earring plugs?
An earplug is a device that is inserted in the ear canal to protect the user’s ears from loud noises, intrusion of water, foreign bodies, dust or excessive wind. Since they reduce the sound volume, earplugs are often used to help prevent hearing loss and tinnitus (ringing of the ears).
