The safe noise level is typically considered to be below 85 decibels (dB) for extended periods of time.

Prolonged loud noise exposure can lead to permanent hearing loss, tinnitus, and other hearing-related issues.

You can measure the decibel level of noise using a decibel meter, which can be purchased at many electronics stores. There are also several apps that measure noise levels.

To protect yourself from loud noise, you can use earplugs or noise-cancelling headphones, keep the volume down on personal devices, and limit your time in noisy environments.

Symptoms of hearing damage from loud noise can include ringing in the ears, difficulty understanding speech, and a decrease in overall hearing ability.

Once your hearing is damaged by loud noise it is typically permanent and cannot be reversed. The best way to protect your hearing is to prevent damage in the first place by avoiding excessively loud noises and using protective gear when necessary.
