Various methods of ear clearing such as yawning, swallowing, or chewing gum may be used to intentionally open the tube and equalize pressures. When this happens, humans hear a small popping sound, an event familiar to aircraft passengers, scuba divers, or drivers in mountainous regions.
The outer ear pathway corresponds to the sound pressure generated in the ear canal cavity due to the vibration of the ear canal wall, which constitutes the source of the occlusion effect. At low frequencies, the outer ear pathway is negligible when the ear canal is open but dominates when it is occluded.
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.
Tinnitus can sound like buzzing, ringing in the ears, and even clicking. This condition can cause stress and discomfort, but there's a way to find relief.
First-line treatment options are generally aimed at treating the underlying cause and include attempting to "pop" the ears, usually via the Valsalva maneuver, the use of oral or topical decongestants, oral steroids, oral antihistamines, and topical nasal steroid sprays, such as Flonase.

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]
