What should parents do if they fail the hearing screening?

Hearing loss is the most common congenital birth defect in the world. The incidence rate of permanent hearing loss accounts for about 20% of all birth defects, with the incidence rate ranging from 1/1000 to 3/1000. Normal listening is a prerequisite for people to learn a language, The brain needs both ears to receive external stimuli continuously before it can acquire language. If children with hearing impairment are not diagnosed and treated in time, they will lose the ability to socialize and learn, bring them difficulties in life and psychological trauma, and eventually become a burden on their families and society. Hearing impairment in infancy can cause devastating damage to language learning, causing children to be deaf and dumb. If Read More …

Hearing aids: Don’t make it a habit for the elderly [not to hear]

Hearing problems are very common among the elderly, The causes of senile hearing loss are various. At present, there is a relatively consistent view that it is related to the natural aging of the auditory system, the gradual accumulation of noise exposure, genetic factors, etc. The elderly not only show that they cannot hear some sounds, It is also manifested in the inability to understand each other’s words, which is even more prominent in the environment where children and grandchildren gather together and laugh. So does it mean that people are old and can’t hear, forget it? Or is it clear that your ears do not listen? Many studies have suggested that the elderly with hearing loss, As it becomes Read More …

Cochlear implant

1. Is what a cochlear implant? Cochlear implant is an acoustic-electrical conversion device. It can collect and convert the acoustic signals in the environment into electrical signals, which are transmitted to the cochlea of the patient through electrodes to stimulate the remaining nerves and make the patient produce hearing. It includes the need to implant a receiver and electrode into the brain through surgery, and at the same time wear an external device to collect sound, similar to an earphone. Work together to make the patient hear the sound. Generally speaking, cochlear implants can help patients with extremely severe hearing impairment to feel the speech sound with a frequency of 100 Hz to 6,000 Hz and a sound intensity of Read More …

Training injury and blast deafness

Long-term exposure to ultra-high decibel sounds such as shooting and explosion without proper protection may cause hearing damage, which is called “knock deafness”. Artillery often suffers from “knock deafness”. Manifestations of blast deafness The damage of noise to ears generally develops from temporary hearing loss to permanent hearing loss. At first, you may only feel the buzzing of your ears, that is, tinnitus, and then slowly progress to hearing loss. People who have been exposed to strong noise for a long time may also feel headache and dizziness, which will affect sleep and cause problems such as increased blood pressure, decreased immune function, gastrointestinal discomfort, etc. With the extension of the exposure time to noise, or the hearing loss caused Read More …

Training Injury · Ear Barotrauma, Ear Deep Water Injury

Ear barotrauma and deep-water ear crush often occur in air force, navy and parachuting troops. Why do ear barotrauma and deep-water ear crush occur? There is a layer of membrane in the ear, which is the tympanic membrane, also known as the eardrum. Outside the tympanic membrane is the external auditory canal. The tympanic membrane is connected to the back of the nose through a channel called eustachian tube. Therefore, there is air inside and outside the tympanic membrane. Under normal circumstances, the air pressure on both sides of the tympanic membrane should be equal. During the rapid ascent and descent of the plane, Either the diver gradually rises to the surface of the water, or when diving, the surrounding Read More …

Mom, be careful, this disease seriously affects the baby’s intelligence, and must be checked and treated as early as possible!

Do precious mothers still remember? Two to three days after the baby is born, the doctor will take blood from the baby’s heel for an examination. Is it what? Congenital hypothyroidism Yes, it is the baby’s thyrotropin TSH that is taken from heel blood for examination. This examination can preliminarily judge whether the baby has congenital hypothyroidism. Congenital hypothyroidism (hereinafter referred to as [congenital hypothyroidism]) is caused by congenital thyroid defects of the baby or iodine deficiency in the mother’s diet during pregnancy, which can seriously affect the baby’s intellectual and physical development. One in every 2,000 newborns is congenital hypothyroidism. What are the hazards of congenital hypothyroidism? Thyroid hormone is very important to human body, especially to infants. 1. Read More …

What should I do if I suffer from sudden deafness?

Deafness is a common hearing disease. There are many kinds of deafness, including [occupational noise deafness] [knock deafness], etc. However, there is a kind of deafness that is quite strange. Patients will suddenly become deaf without warning one day. In medicine, this kind of deafness is called [sudden deafness], also called [sudden deafness]. If a person’s hearing drops rapidly in a short period of time or within 3 days, which is manifested by a hearing drop of ≥ 30 decibels at three connected frequencies (such as 500 Hz, 1000 Hz and 2000 Hz on pure tone audiometry), and is usually caused by monaural onset, then he is likely to suffer from sudden deafness. If you don’t know what kind of Read More …

Who is more harmful to ears, ordinary earphones or in-ear earphones?

(The above picture shows ordinary earphones; The following figure shows in-ear headphones.) First, the damage caused by listening to earphones belongs to chronic sound damage. The damage of sound to hearing is called noise deafness in medicine. Noise deafness is mainly divided into chronic sound injury and acute sound injury: A. Chronic sound injury: refers to slow sensorineural deafness caused by long-term exposure to noise stimulation. B. Acute sound injury: It is caused by close explosion (such as bomb explosion nearby during war) and is caused by instantaneous exposure of high-intensity impulse noise. II. Noise Intensity and Exposure Time The severity of noise damage to hearing is mainly determined by noise intensity and exposure time. The greater the intensity, the Read More …
