How do hearing aids work for noise-induced hearing loss?

Since noise-induced hearing loss reduces the volume and what you hear, a hearing aid makes up for that loss by acting as a miniature amplification system in your ear. They use tiny microphones that catch sounds that your naked ear might miss. These sounds are transferred to a small speaker that rests in your ear canal. Hearing aids, however, will not help with the warping and lack of clarity that you may experience with sounds.
