   www.aol.com/crackling-ear-causes-home-treatments...

   Key Takeaways. Crackling in the ear is often due to an issue with the Eustachian tube opening and closing properly. Occasional crackling in the ear home remedies can help (see our suggestions below).

3. Patulous Eustachian tube - Wikipedia

   en.wikipedia.org/wiki/Patulous_Eustachian_tube

   Patulous Eustachian tube is a physical disorder. The exact causes may vary depending on the person and are often unknown. [5] Weight loss is a commonly cited cause of the disorder due to the nature of the Eustachian tube itself and is associated with approximately one-third of reported cases. [6]

4. Tympanic membrane retraction - Wikipedia

   en.wikipedia.org/wiki/Tympanic_membrane_retraction

   The majority of tympanic membrane retractions do not cause any symptoms. Some cause hearing loss by restricting sound-induced vibrations of the eardrum. Permanent conductive hearing loss can be caused by erosion of the ossicles (hearing bones). Discharge from the ear often indicates that the retraction pocket has developed into a cholesteatoma.

5. Eustachian tube - Wikipedia

   en.wikipedia.org/wiki/Eustachian_tube

   In humans and other tetrapods, both the middle ear and the ear canal are normally filled with air. Unlike the air of the ear canal, however, the air of the middle ear is not in direct contact with the atmosphere outside the body; thus, a pressure difference can develop between the atmospheric pressure of the ear canal and the middle ear.

6. Inner ear decompression sickness - Wikipedia

   en.wikipedia.org/wiki/Inner_ear_decompression...

   History of difficult ear clearing or forced Valsalva manoeuvre: No history of eustachian tube dysfunction Low-risk dive profile: Depth >15 m, helium mixtures, helium to nitrogen gas switches, repetitive dives Isolated inner ear symptoms, or inner and middle ear on the same sides: Other neurological or dermatological symptoms suggestive of DCS

7. Tensor tympani muscle - Wikipedia

   en.wikipedia.org/wiki/Tensor_tympani_muscle

   The tensor tympani acts to damp the noise produced by chewing. When tensed, the muscle pulls the malleus medially, tensing the tympanic membrane and damping vibration in the ear ossicles and thereby reducing the perceived amplitude of sounds. It is not to be confused by the acoustic reflex, but can be activated by the startle reflex.

8. Ear clearing - Wikipedia

   en.wikipedia.org/wiki/Ear_clearing

   Diver clearing ears Section of the human ear, the Eustachian tube is shown in colour. Ear clearing, clearing the ears or equalization is any of various maneuvers to equalize the pressure in the middle ear with the outside pressure, by letting air enter along the Eustachian tubes, as this does not always happen automatically when the pressure in the middle ear is lower than the outside pressure.

9. Musical ear syndrome - Wikipedia

   en.wikipedia.org/wiki/Musical_ear_syndrome

   Musical ear syndrome (MES) is a condition seen in people who have hearing loss and subsequently develop auditory hallucinations. "MES" has also been associated with musical hallucinations , which is a complex form of auditory hallucinations where an individual may experience music or sounds that are heard without an external source.
