Hearing loss is one of the important health problems that often occurs in the elderly. Hearing loss in adults can be caused by many different reasons and can develop at different levels of severity depending on the health of each person. Hearing loss is not life-threatening but greatly affects the psychology and daily life of the patient.

According to statistics, for every 1000 children born, 3-4 have congenital hearing loss. Hearing loss in infants and young children affects the process of learning to speak and communicate in language. Many cases of severe hearing loss, deafness,... can lead to muteness, greatly affecting the future.

Hearing is a part of us from birth, but not everyone understands sound, how the auditory system works, and the causes of hearing loss.

Hearing loss is often related to age or injury. It is not life-threatening, but it can cause problems in daily life, so it needs to be diagnosed and treated appropriately.

Damage to any part of the ear can lead to hearing loss. Loud sounds often damage the inner ear (cochlea). Damage can result from a single exposure to extremely loud sounds or from long-term exposure to loud sounds. Noise damages the cells and membranes in the cochlea.

Epitympanitis is a form of otitis media, the disease has no clear clinical manifestations. Therefore, it is difficult to detect, patients are often subjective, causing the inflammation to become more severe, progressing to become chronic.

The Eustachian tube is a communication organ between the middle ear and the pharynx to create pressure between the inside and outside of the eardrum. When the Eustachian tube is blocked, it will cause tinnitus and hearing loss. Eustachian tube inflation is a method to help clear the blockage of the Eustachian tube when non-invasive methods are not possible.

Sound therapy is the use of another type of sound to mask the tinnitus, helping the patient to focus less on the tinnitus. Choosing the right sound device will help improve the condition better.
