Tinnitus (ringing, buzzing or hissing in the ears) that occurs for only a short time after exposure to high noise levels is an early warning sign that your hearing is at risk and you may have suffered some permanent loss of hearing acuity.
The name of this noise is Crepitus. Crepitus is a medical term to describe the grinding, crackling or popping sounds and sensations experienced in the joints. It is possible that the noise is coming from scar tissue which is normal wear and tear on the joints. This sound happens when two rough surfaces in the human body come into contact.
