About Hearing Loss

Q: How do I know if I have hearing loss?

A: If you frequently encounter the following situations in daily life, your hearing may be impaired:

In social interactions and communication:

Often asking others to repeat themselves: You frequently say "What?" or "Sorry, could you repeat that?", especially when there is mild background noise.

Difficulty hearing high-frequency sounds: Struggling to hear women's or children's voices clearly, or finding it hard to distinguish consonants like "s," "f," and "th," leading to misunderstandings (e.g., hearing "fifteen" as "fifty").

Difficulty communicating in noisy environments: In places like restaurants, family gatherings, or shopping malls, you feel everyone's speech blends together, making it hard to follow conversations and leaving you feeling very tired.

Feeling like others are mumbling or speaking unclearly: You start to think the problem is with how others are speaking, rather than considering your own hearing may be declining.

Unable to hear the other person clearly on the phone: Regardless of which ear you use, the voice on the other end sounds muffled, and you often need to increase the call volume.

During device use and entertainment:

Increasing electronic device volume without realizing it: Family or colleagues complain that the volume of your TV, phone, computer, or headphones is too loud, while you feel it is just right.

Difficulty enjoying music or missing doorbells/phone rings: You find yourself unable to hear your phone ringing or the doorbell, or feel that music has lost its former clarity and depth.

Physical and Perceptual Changes:

Tinnitus: Frequent ringing, buzzing, hissing, or other noises in one or both ears, particularly more noticeable in quiet environments (such as when preparing to sleep at night).

Listening Fatigue: Feeling unusually tired, experiencing headaches, or increased stress after situations requiring concentrated listening, like meetings or conversations.

Worsened Balance or Dizziness: The inner ear is responsible not only for hearing but also for balance. If hearing loss is accompanied by dizziness, it may indicate an issue with the inner ear.

Feeling of Fullness or Pressure in the Ears: A sensation that the ears are blocked or that sounds seem distant.

If you notice multiple signs from the list above, it is essential to take them seriously. Hearing loss is often gradual, making it difficult to self-detect immediately. Consulting an ENT doctor or audiologist for a professional hearing test is the most crucial step you can take to protect your hearing and quality of life. Timely intervention (such as using hearing aids) can effectively slow the progression of hearing loss and significantly improve your daily communication and mental well-being.

(If you frequently experience the following in daily life, your hearing may be impaired:

Communication Breakdowns: Often needing others to repeat themselves, especially in noisy environments; frequently feeling that others mumble.

Unconsciously Increasing Volume: Family members complain that your TV or headphone volume is too loud; finding the other person's voice too quiet during phone calls.

Persistent Tinnitus: Hearing cicada-like chirping or buzzing sounds in quiet surroundings.

Difficulty Hearing High-Pitched Sounds: Struggling to hear women, children, or the telephone ring.

If you experience these signs, it is advisable to get a hearing test promptly.)

Q: How can I know the extent of my hearing loss?

A: You can make an initial estimate by comparing your daily hearing experiences with the WHO 2021 grading standard for hearing loss:

Step 2: Seek Professional Hearing Testing (The Only Accurate Method)
To obtain precise information about the degree and type of your hearing loss, you must visit an ENT department at a hospital or a professional hearing center. An audiologist will perform a painless and precise test for you—pure-tone audiometry.

You will wear headphones in a soundproof booth and hear sounds at different frequencies (pitches) and intensities (loudness levels).

After the test, you will receive an "audiogram."
A professional will use this chart to accurately explain the degree of hearing loss in each ear (mild, moderate, severe, or profound), identify the type (such as sensorineural, conductive, etc.), and provide personalized intervention recommendations (such as whether hearing aids are needed).

Q: What is the difference between sensorineural hearing loss and conductive hearing loss?

A: Sensorineural hearing loss is very common and occurs when the inner ear or auditory nerve is damaged due to factors such as noise exposure, genetics, or natural aging. It develops gradually over time and may subtly affect your hearing. Hearing aids can often help alleviate this type of hearing loss, and Waterfall hearing aids are designed to help you re-engage in conversations.

Conductive hearing loss occurs when sound is blocked, much like having clogged ears. It is usually caused by disorders of the outer or middle ear, making all sounds in one or both ears seem muffled or blocked. Most conditions causing conductive hearing loss can be treated. If hearing loss persists after treatment, hearing aids are recommended for intervention. Waterfall Dolphin is particularly suitable for patients with conductive hearing loss due to conditions such as otitis media or congenital malformations in children, as well as those with unilateral hearing loss resulting from various causes.

Q: Should I see a doctor for my hearing loss?

A: While hearing loss doesn't always require a doctor's visit, it's absolutely recommended in certain situations. You should consult a doctor if you experience sudden hearing loss, pain, balance issues, ear pressure, ear drainage, or any other ear-related medical symptoms. Additionally, we advise seeing a doctor if your hearing loss is severe to profound. If your doctor recommends hearing aids, please remember to contact us again to see if Waterfall hearing aids might be suitable for you.

Q: What impact can hearing loss have on me?

Communication and Social Impact

Difficulty Communicating: You may frequently ask others to repeat themselves or misinterpret conversations, leading to inefficient communication and leaving both parties feeling tired and frustrated.

Social Withdrawal: Because listening in noisy environments or group conversations requires significant effort, you may unconsciously avoid gatherings and family activities, gradually becoming isolated and lonely.

Strained Relationships: Family and friends might mistakenly assume you are "inattentive" or "ignoring them on purpose," leading to misunderstandings and conflicts.

Psychological and Emotional Impact

Fatigue and Stress: Your brain has to expend extra energy "decoding" unclear sounds, resulting in significant mental exhaustion.

Anxiety and Depression: Social isolation and communication barriers can easily trigger feelings of loneliness, reduced self-confidence, and even increase the risk of anxiety and depression.

Irritability and Suspicion: The constant struggle to hear clearly can lead to frustration, emotional instability, and sometimes even make you suspect that others are speaking ill of you behind your back.

Safety and Cognitive Impact

Safety Risks: You may fail to hear distant car horns, fire alarms, smoke detectors, or others' warnings, increasing the risk of accidents.

Cognitive Decline: Research shows that untreated hearing loss significantly increases the risk of cognitive decline and dementia. This occurs because the auditory centers in the brain atrophy due to lack of stimulation, while excessive brain resources that should be allocated to memory and thinking are diverted to processing sounds.

Important Note: These impacts are not inevitable. Taking proactive steps (such as using hearing aids) can effectively slow hearing deterioration, improve communication, significantly reduce the risks mentioned above, and greatly enhance your quality of life.

Q: How do hearing aids work?

A: Air-conduction hearing aids follow the natural path of sound transmission through air. They use a microphone to collect sound, which is then amplified and processed by a chip before being delivered by a receiver. The sound travels through the ear canal, eardrum, and middle ear to reach the inner ear. This type is suitable for the vast majority of people with hearing loss.

Bone-conduction hearing aids bypass the outer and middle ear, transmitting sound directly via bone conduction. They convert sound signals into mechanical vibrations. A vibrator then directly stimulates the skull bones, transmitting the signals to the inner ear, allowing it to "perceive" the sound directly. This type is suitable for individuals with severe outer/middle ear disorders who cannot use air-conduction hearing aids.

Core Difference: Air-conduction hearing aids amplify sound and deliver it into the ear via air; bone-conduction hearing aids create vibrations that directly stimulate the inner ear through the skull bones.

Q: Do I need to wear hearing aids in both ears?

A: For most patients with bilateral hearing loss, wearing hearing aids in both ears is the preferred and most effective rehabilitation solution.

You can assess whether you need binaural fitting based on the following points:

Core Advantages of Binaural Hearing Aid Fitting:

Improved Speech Clarity in Noise: Binaural hearing allows the brain to integrate and compare signals from both ears. Much like "noise-cancelling headphones," this helps automatically filter out background noise, making it easier for you to hear clearly in settings like dinners and social gatherings.

Accurate Sound Localization: Your two ears function like the body's natural "radar system," determining the location of a sound source based on minute differences in the time and intensity at which sounds arrive at each ear. This is a crucial safety skill, for instance, when judging the direction of traffic while crossing a street.

Better Sound Loudness and Quality: Listening with both ears requires less overall volume, resulting in a more natural, fuller, and richer stereophonic sound experience. This significantly reduces the listening fatigue often associated with using only one hearing aid.

Prevention of "Auditory Deprivation": If only one ear is aided, the unaided ear may suffer from a gradual decline in the brain's ability to process sound due to long-term lack of auditory stimulation. This can potentially lead to a worsening of hearing loss in that ear.
