UNS – Universitas Sebelas Maret Hospital (RS UNS) held the Healthy Dialogue Program to mark World Hearing Day 2025. The discussion carried the theme “The Noise You Consider Normal Can Damage Your Hearing.” dr. Rini Kartika Dewi, Sp.THT-KL, an ENT (Ear, Nose & Throat) specialist at RS UNS, served as the speaker. dr. Hasraprilliana Hersya, a general practitioner, moderated the session. The UNS Hospital YouTube channel broadcasted the event live.
The Hidden Dangers of Noise Exposure
Many people underestimate how everyday noise can damage their hearing. dr. Rini explained that exposure to sounds exceeding 85 decibels (dB) can cause permanent hearing loss. This noise level is equivalent to the sound of a medium-sized truck. Prolonged exposure increases the risk, yet symptoms may not appear until years later.
Noise-induced hearing loss depends on internal and external factors. Medical conditions like hypertension and diabetes affect blood circulation in the ears, increasing vulnerability. Certain ototoxic medications can cause permanent hearing damage. Anatomical factors, such as ear canal length, also influence noise sensitivity.
External factors significantly contribute to hearing impairment. Factory, construction, and music industry workers face frequent exposure to high noise levels. The widespread use of earphones and True Wireless Stereo (TWS) devices worsens the issue. Prolonged exposure to high volumes gradually weakens auditory function.
Early Signs and Prevention Strategies
Noise-induced hearing loss occurs when the auditory nerves suffer damage, classifying it as sensorineural hearing loss. One of the earliest warning signs is tinnitus, a persistent ringing sensation in the ears. Some individuals may also experience balance disorders, such as dizziness when changing positions. dr. Rini emphasized that early detection through audiometric exams is crucial, as it allows for timely intervention before the damage becomes irreversible.
To minimize risks, she recommended the 60-60 rule. Users should limit audio device use to 60 minutes daily at no more than 60% volume. She warned that excessive vibrations damage cochlear hair cells. Sustained exposure to high decibel levels can harm auditory nerve synapses, causing permanent impairment.
Protecting Hearing in Work and Daily Life
People frequently exposed to loud environments must take protective measures. The Regulation of the Minister of Manpower and Transmigration (PER.13/MEN/X/2011) sets noise exposure limits for workers. This regulation emphasizes the importance of Personal Protective Equipment (PPE). Earmuffs reduce noise by 40-60 dB and offer better protection than earbuds. Concert-goers should use them for optimal safety.
Regular hearing screenings are essential for prevention. Workers exposed to high noise levels should take Audiometry and Otoacoustic Emissions (OAE) tests yearly. These tests help monitor their hearing threshold.
Available Treatments for Hearing Loss
People with significant hearing loss can manage the condition with various treatments. Psychotherapy strengthens emotional resilience. Hearing aids help maintain communication and reduce the social impact of hearing impairment. Speech therapy supports language and hearing rehabilitation when speech ability is affected.
“With early detection, prevention, and proper treatment, we can protect our hearing health,” dr. Rini concluded. “These efforts help us maintain a good quality of life.”
