What causes joints to make snapping, popping noises? Q: I am a 20-year-old in okay shape and health, but the joints in my upper and lower back and shoulders are always stiff and snap all the time. Are noisy joints the sign of some problem? A: Snapping and popping of joints is common. The sound you hear is caused by air bubbles in the synovial fluid â the liquid that surrounds and lubricates your joints â and by the snapping of tightly stretched ligaments as they slide off one bony surface onto another.
I sometimes hear a crackle sound in my ear. The doctor said it was probably tinnitus, but I do not experience a ringing sound and it only happens when I move my jaw. Answer Wiki. The movement of your jaw produces the movement of the joint capsule between mandible (jaw bone) and temporal bone. This is very close to the ear. This produces a sound that's not intense or hardly noticeable except when you're in a quiet room. If it is intense, then there could be excess earwax in your ear canal. Even this produces a crackling sound.
