Crackling Sound in Ear — Causes and Treatment

A crackling, popping, or clicking sound in the ear can be annoying and sometimes worrying. In most cases, the cause is harmless and treatable, but persistent or severe symptoms warrant professional assessment.

Common causes

• Eustachian tube dysfunction — the most common cause. The eustachian tube connects the middle ear to the back of the throat and helps equalise pressure. When it becomes partially blocked — often due to a cold, allergies, or sinus congestion — it can cause crackling or popping sounds, especially when swallowing, yawning, or chewing.
• Ear wax — wax sitting against the eardrum or in the ear canal can cause crackling sounds, particularly during jaw movement.
• Middle ear infection (otitis media) — fluid behind the eardrum can cause crackling, popping, and muffled hearing.
• TMJ (temporomandibular joint) disorders — problems with the jaw joint, located just in front of the ear, can produce clicking or crackling sounds that seem to come from the ear.
• Myoclonus — rare involuntary spasms of muscles in the middle ear or palate can cause rhythmic clicking.

Home remedies

For eustachian tube dysfunction:

• Swallowing, yawning, or chewing gum to help open the eustachian tube
• Valsalva manoeuvre — gently blow with your nose pinched and mouth closed
• Steam inhalation — can help relieve congestion
• Decongestant nasal sprays — short-term use (max 7 days) to reduce swelling
• Antihistamines — if allergies are contributing

When to see a doctor

See your GP if:

• Crackling persists for more than 2 weeks
• You have hearing loss alongside the crackling
• There is pain, discharge, or bleeding from the ear
• The sound is rhythmic and matches your heartbeat (pulsatile — see your GP promptly)
• You have dizziness or balance problems
