Hey doctor, how do i know your   hearing aids   is good? Yes, there is the methods of hearing aid effect evaluation include sound field test, hearing aid threshold, speech test, real ear analysis, and questionnaire.   1.Hearing aid hearing threshold evaluation: Verification of the sound adjustment of the hearing aid by waving the smallest sound that can be heard after wearing the hearing aid, which is one of the most widely used verification methods.   2. Questionnaire survey evaluation: It refers to whether the hearing aids after fitting can achieve the desired effect. Audiologists need to make subjective judgments on the benefit effect and final effect of the patient through a standardized questionnaire. This method is used more abroad.   3. Speech test: After wearing the hearing aid, play the recorded vocabulary list through headphones or speakers. This list is divided into monosyllables, two-syllables and short sentences. When the user hears a word, he repeats it, and records the n

HOW TO PROTECT OUR HEARING

25dB is considered normal hearing, 25-40dB is considered mild hearing impairment. Hearing loss can lead to impairment in interaction, so we have to pay more attention to the hearing problems. If there is an abnormality, further examination of the ear is recommended. An otoscopy can be performed to identify the specific cause and treat it as soon as possible to avoid further hearing loss. Follow are tips for protecting our hearing in the daily life: 1. Stay away from noise, which can damage the inner ear and accelerate the onset and development of early age-related deafness, so avoid exposure to noise, especially to firecrackers, explosions and strong gongs and drums, etc.   2. Early detection and treatment.   3. Quit smoking and drinking, do not use ototoxic drugs, etc.; nicotine and alcohol can directly damage the auditory nerve, and long-term heavy smoking and drinking can also lead to cardiovascular and cerebrovascular diseases, resulting in insufficient blood supply to the inner ea

THE LIFE OF A HEARING AID

When we go to the hearing centers or hearing clinics, people with hearing loss always ask for the audiologist before they get a hearing aid: How long will the   hearing aid   last? The answer to this question is usually 5 to 8 years. In fact, even if the same hearing aids are used by different people, their “life” are varies greatly. Some people may wear their hearing aids for 2 or 3 years before the hearing aids start to be overhauled, the shell is damaged, the sound is distorted and the hearing aids have to be replaced; but Some people may wear their hearing aids for 10 years, and the hearing aids still look intact and sound good. So, how long do hearing aids last? It is related about what factors can affect the life of a hearing aid and how can we extend the life of hearing aids.   There are 6 factors affect the life of a hearing aids:   1.The materials for the manufacture of hearing aids. While most hearing aids are designed to be durable, some components are made of plastic, metal

HOW HEARING WORKS TO PEOPLE

Normal ear functions Hearing is an important sense to your everyday life. From alarms to important conversations throughout the day, our sense of hearing is important to communicating information. The way the auditory system works is incredibly complex and requires a number of functions to work properly, including:  1.Sound is transmitted through the air as sound waves from the environment. The sound waves are gathered by the outer ear and sent down the ear canal to the eardrum. 2.The sound waves cause the eardrum to vibrate, which sets the three tiny bones in the middle ear into motion. 3.The motion of the three bones causes the fluid in the inner ear, or cochlea, to move. 4.The movement of the fluid in the inner ear causes the hair cells in the cochlea to bend. The hair cells change the movement into electrical impulses. 5.These electrical impulses are transmitted to the hearing (auditory) nerve and up to the brain, where they are interpreted as sound.   The function of different ear

INTRODUCTION OF RECHARGEABLE CIC HEARING AIDS

CIC hearing aids Description Q series (Q10/Q8/Q6/Q4/Q2) are  hearing aids  that adopts digital processing technology to amplify sound signals and automatically eliminates sound feedback. lt is suitable for patients with sensorineural, conductive and mixed hearing loss with hearing loss ≤80dBHL. lt is easy to wear and operate. Two types of earplugs (closed and open) are available.   lt has a full-frequency intelligent noise processing system, which can be worn in different working and living environments. From Q2 to Q10, it provides 6dB to 18dB different noise processing capabilities. C and button controls can be selected to realize different functions (volume,program, sleep) according to different time (1s,2S,5S).   Features The shape of the Sound Amplifier conforms to the structure of the human ear canal and it is invisible and comfortable to wear. It is not only suitable for listening in quiet environments, but also for noisy environments.  It is available or both ears.     Technical
