What are Some Risk Factors for Hearing Loss?
Have you noticed that conversations in noisy places have become harder to follow, or that you find yourself asking people to repeat themselves more often than before?
These can be early signs of hearing loss. The factors commonly linked to these signs include aging, prolonged noise exposure, and genetics, which should be recognized early to help protect your hearing and reduce the risk of further decline.
What is Hearing Loss?
Hearing loss refers to a partial or complete loss of hearing in one or both ears. It is categorized into three types:
- Conductive Hearing Loss: Occurs when sound cannot physically pass through the outer or middle ear. This is often due to fluid buildup, earwax blockages, or eardrum damage. Sound cannot reach the inner ear properly.
- Sensorineural Hearing Loss: This is the most common type of hearing loss. It typically affects the inner ear, leading to the brain and is closely linked to aging and noise exposure.
- Mixed Hearing Loss: A combination of conductive and sensorineural hearing loss affecting the ear at the same time.
How Does Hearing Actually Work?
Hearing involves several parts working together, and hearing difficulties can arise when any part is damaged, blocked, or worn down.
- Outer Ear: Gathers sound waves from the environment and channels them toward the ear canal.
- Middle Ear: The eardrum vibrates as sound arrives. Three small bones amplify those vibrations and pass them forward.
- Inner Ear (Cochlea): Thousands of tiny hair cells convert vibrations into electrical signals.
- Brain: The auditory nerve transmits those signals to the brain, where they are interpreted as recognizable sound.
Common Signs of Hearing Loss to Watch For
In the Philippines, everyday environments from busy roads and crowded public transport to noisy workplaces and family gatherings, background noise often masks symptoms of hearing loss until they become harder to ignore.
- Muffled Speech and Sounds: Consonants such as “s,” “f,” and “th” become difficult to distinguish, and speech may sound indistinct even at close range.
- Frequent Requests to Repeat: Regularly asking family members to speak more loudly.
- High Volume Threshold: Setting the TV or radio to higher levels, which others in the room find uncomfortable.
- Social Withdrawal: Avoiding family gatherings or reunions because keeping up with conversation has become exhausting.
- Tinnitus: A persistent ringing or buzzing in the ears that others cannot hear.
- Impression of Mumbling: The sense that others are not speaking clearly, when the difficulty lies with your hearing rather than the speaker.
Key Risk Factors for Hearing Loss
Several risk factors can contribute to sudden hearing loss at any stage of life.
1. Aging
As the inner ear ages, the hair cells that convert sound into signals gradually break down, making it difficult to detect certain sounds clearly. A national survey shows that 49.1% of Filipinos aged 65 and above have moderate or worse hearing loss.
2. Exposure to Loud Noise
Exposure to loud noise is a common risk factor for hearing loss, whether it happens gradually over time or all at once. Sounds above 85 decibels, when heard repeatedly over long periods, can damage the hair cells inside the cochlea that help convert sound into signals for the brain.
A single burst of extreme sound, such as a firework blast during New Year celebrations or a firearm discharge, can also cause immediate and permanent harm to the inner ear. This is why the Department of Health (DOH) in the Philippines cautions the public during the New Year season that fireworks can also cause hearing loss.
Firearms at shooting ranges, industrial explosions, and repeated exposure to blast noise in military or police service carry the same risk of permanent hearing damage.
3. Loud Occupational Noise
Certain professions carry a higher risk of hearing loss because of regular exposure to high noise levels in the workplace. The Department of Labor and Employment (DOLE) sets Occupational Safety and Health (OSH) standards, including permissible noise exposure limits, to help reduce this risk, but those in the following roles remain at high risk:
- Construction workers
- Manufacturing staff
- Seafarers in engine rooms
- BPO employees
- Traffic enforcers
5. Recreational Noise and Personal Audio Devices
Unsafe listening habits can increase the risk of hearing loss, especially when high sound exposure becomes part of daily routines. The World Health Organization (WHO) warns that more than 1 billion young people worldwide are at risk of hearing impairment due to such habits.
High-volume use of earphones or gaming headsets, as well as regular motorcycle riding without ear protection, can all contribute to premature hearing damage over time. Repeated exposure to loud recreational noise can gradually affect the inner ear and lead to hearing loss earlier than expected.
6. Genetics
Some people inherit a higher risk of hearing loss due to genetic factors. A family history of hearing loss can increase the likelihood of developing hearing changes earlier or over time, even without noise exposure or other external causes.
7. Earwax Buildup
Earwax traps dust and debris before it reaches deeper structures in the ear. When the buildup exceeds, it forms a blockage that dampens sound and can create the impression of muffled hearing. Such earwax buildup may contribute to hearing loss when left unaddressed.
8. Head Trauma and Sudden Pressure Changes
Head injury may cause hearing loss by damaging the eardrum or inner ear structures. Rapid pressure changes, such as those experienced during diving or flying with a severe cold, can have a similar effect.
The Complications of Ignoring Hearing Loss
Loss of hearing that goes unaddressed not only affects the ears, but it is also linked to:
- Cognitive Decline: Untreated hearing loss is considered a risk factor for dementia in later life.
- Depression and Social Withdrawal: Older people with hearing difficulties are more likely to disengage from family gatherings. This may lead to social withdrawal or the risk of depression.
- Increased Fall Risk: Reduced hearing affects spatial awareness and balance, raising the likelihood of falls.
- Reduced Earning Capacity: Workers with unaddressed hearing loss can face challenges in roles that rely on verbal communication, listening, and day-to-day interaction.
- Strained Family Relationships: When loved ones are asked to repeat themselves, conversations can become frustrating for everyone involved, sometimes creating emotional distance.
How to Protect Your Hearing
Protecting your hearing involves consistent habits that reduce long-term exposure to damage.
1. Manage Your Noise Exposure
Keep personal device volumes at 60 percent or below and take breaks during extended listening sessions. In high-noise environments, move away from the source where possible and limit total exposure time.
2. Invest in Custom Ear Plugs for High-Risk Activities
Custom-fit ear plugs, such as those offered by Hear Life PH, can help reduce noise exposure during high-risk activities. They can be useful for musicians, motorcyclists, shooters, and industrial workers who need hearing protection for extended periods.
3. Manage Underlying Health Conditions
Diabetes, hypertension, and poor cardiovascular health can increase the risk of hearing loss by affecting the tiny blood vessels and nerves that support the inner ear.
The cochlea relies on a steady supply of oxygen-rich blood to keep the sensory hair cells functioning properly. When blood circulation is reduced or blood sugar remains poorly controlled over time, these structures can become damaged, making it harder to detect and process sound.
4. Get Regular Hearing Tests
Regular hearing assessments can reveal whether any change in hearing has occurred. This allows hearing loss to be identified early, monitored over time, and managed before it affects everyday communication and quality of life.
