The causes of foamy sound in the ears may be external ear canal diseases, secretory otitis media, phantom hearing, etc. 1. Diseases of the external auditory canal: such as cerumen and foreign bodies in the external auditory canal may irritate the tympanic membrane, which may lead to the foamy sound in the ear. 2. Secretory otitis media: Mainly secretory otitis media may cause foamy sounds in the ears, accompanied by hearing loss, due to the accumulation of fluid in the middle ear drum chamber, especially during head movement, yawning or nose blowing. 3. Phantom hearing: Patients usually do not have organic lesions, but due to mental or psychological abnormalities such as stress and anxiety, the symptoms of foamy sounds in the ears may occur. If there are symptoms of foamy sounds in the ears, you should consult a doctor in time and standardize the treatment after diagnosis and clarification.
