Hearing Loss Overview
The ear consists of the outer, middle, and inner sections; hearing loss occurs when any part of this system fails to transmit sound correctly.
Types of Hearing Loss：
Conductive: Issues in the outer or middle ear.
Sensorineural: Issues in the inner ear or auditory nerve (the most common type).
Mixed: A combination of both conductive and sensorineural loss.
Conductive Hearing Loss:
Occurs when the outer or middle ear cannot transmit sound properly.
Causes: Ear trauma, blockages (wax or foreign objects), infections, perforated eardrums, or congenital conditions (e.g., Down syndrome, Treacher Collins).
Solutions：
Standard Hearing Aids: May be less effective if chronic inflammation or malformation is present.
Bone Conduction Aids: Uses a headband vibrator behind the ear.
BAHA (Bone Anchored Hearing Aid): A surgically implanted screw connects the device to the skull.
Mechanism: If the inner ear is healthy, these devices bypass the blockage by vibrating the skull to send sound directly to the inner ear.
Sensorineural Hearing Loss
The most common type of hearing loss, typically resulting from issues within the inner ear or the auditory nerve.
Common Causes of Congenital Hearing Loss:
Genetic factors
Viral infections
Prematurity
Birth trauma (e.g., hypoxia)
Acquired Factors:
Ototoxic medications (damaging to the auditory system)
Head trauma
Noise-induced damage
Age-related hearing loss
Ear infections
Meningitis
Encephalitis
Other diseases
Hearing Self-Assessment
If you answer "Yes" to 2 or 3 of these questions, you may have hearing loss. We recommend visiting a professional hearing center for a test.
Do others often complain that your TV or radio is too loud?
Have you missed visitors or calls because you didn't hear the doorbell or phone?
Do you find it difficult to communicate in noisy environments?
Does it often feel like people are mumbling or speaking too softly during daily conversation?
Has anyone told you that you speak too loudly?
Do you frequently ask others to repeat themselves?
Have friends or family suggested you use a hearing aid?
Do you have trouble understanding the lyrics of popular songs on the radio?
Do you find it easier to hear female voices than male voices?
The Audiogram
An audiogram is an essential tool for evaluating hearing loss, used by specialists to select the most suitable hearing aid for you. After completing a hearing test at a certified medical facility, always request a copy of your audiogram and keep the report to track any changes in your hearing over time.

Prevention & Treatment
Prevention:
Avoid ear injuries by wearing ear muffs and never inserting fingers, swabs, or tissues into the ear canal. Protect your hearing by using earplugs in loud environments and strictly controlling the volume and duration of headphone use.
Treatment:
Consult a doctor to diagnose your hearing loss and prevent further decline through medical intervention. With the help of a professional dispenser, you can improve your hearing with the right device. SoundWear provides free, professional fitting services for the hearing impaired.
Hearing Aid Types & Selection
Pocket (Box) Type: Worn in a pocket and connected to an earphone via a wire; though bulky and less aesthetic, it offers high power and multiple controls, making it ideal for seniors and children with severe hearing loss.
Eyeglass Type: Combines corrective eyewear with a hearing aid (often bone conduction); however, the two components are inseparable, making repairs inconvenient and costs high.
BTE (Behind-the-Ear): A curved device hooked over the ear that delivers sound through a tube and earmold; its durable design and larger battery provide higher power, making it a reliable choice for children.
Custom (ITE/ITC/CIC): Tailor-made to fit the unique shape of the user's ear canal; these devices offer maximum comfort, a discrete appearance, and are easy to wear.
Open-Fit: Features a slim, flexible tube for a more comfortable and stylish fit than traditional BTEs; it is best suited for users with mild to moderate hearing loss.
Standard Canal (BEE/MCIC): A specialized custom-style device favored for its small, hidden profile; unlike standard models, these typically require a professional ear impression for a perfect factory fit.
