How do you know if earplugs are good?
How do you know if earplugs are good? If fit-testing is not available at your workplace, you can check earplug fit by counting out loud while slowly cupping and uncupping your hands over your ears; if you have a good fit, your voice should sound about the same as you cup and uncup your ears.
How long is too long to wear earplugs?
The length of time that it is safe to wear ear plugs depends on the type of earplugs being used, as well as the individual wearing them and the situation they are being used in. For disposable foam ear plugs that are commonly used to block out noise, it is generally safe to wear them for up to 8 hours at a time.
