Causes of Acquired Hearing Loss

One of the most common causes of acquired hearing loss is exposure to loud noise. Whether it’s the result of prolonged exposure to loud music, noisy workplaces, or a sudden, intense sound like an explosion, noise-induced hearing loss can be permanent. The tiny hair cells in the inner ear, responsible for transmitting sound signals to the brain, can be damaged or destroyed by excessive noise levels.

Unlike other cells in the body, these hair cells do not regenerate, making hearing loss permanent. Taking preventive measures, such as wearing earplugs at concerts or using protective gear in industrial environments, can significantly reduce the risk. Regular hearing health exams can also detect early signs of damage before it progresses.

Age-Related Changes

Age-related hearing loss, or presbycusis, develops gradually over time, and this type of hearing loss usually affects both ears and results from the natural aging process. Over the years, wear and tear on the auditory system can impair the ability to hear high-frequency sounds, making conversations in noisy settings challenging.

While age cannot be avoided, maintaining overall health can slow the progression of presbycusis. A balanced diet, regular exercise, and routine hearing health exams can help monitor changes and ensure appropriate interventions are made when necessary.

Ototoxic Medications

Certain medications, known as ototoxic drugs, can harm the inner ear and lead to acquired hearing loss. These include some antibiotics, chemotherapy agents, and high doses of aspirin. The damage can be temporary or permanent, depending on the drug and the dosage.

Hearing health professionals often weigh the benefits and risks of these medications, especially for individuals already at risk for hearing loss. Being aware of medication side effects and discussing concerns with a doctor can help mitigate potential harm.

Infections and Illnesses

Infections, whether in the ear itself or affecting the broader body, are another cause of acquired hearing loss. Middle ear infections, if recurrent or untreated, can cause damage to the eardrum or the bones of the middle ear.

Other illnesses, such as meningitis or measles, can also lead to complications that affect hearing. These conditions may result in sensorineural hearing loss, which impacts the inner ear or the auditory nerve. Early treatment and vaccinations can prevent many of these issues and reduce their impact on hearing.

Head Injuries

Trauma to the head is another significant cause of acquired hearing loss. A direct blow to the skull can damage the inner ear structures, and auditory nerves, or even disrupt the bones of the middle ear.

Individuals involved in contact sports or high-risk activities should take precautions like wearing helmets to prevent such injuries. After any head trauma, a thorough evaluation that includes a hearing health exam can identify and address potential damage.

Chronic Health Conditions

Underlying health conditions such as diabetes, hypertension, and heart disease can also contribute to acquired hearing loss. These conditions affect blood flow and can impact the delicate structures within the ear.

Managing chronic conditions effectively is key to reducing the risk of hearing damage. Regular check-ups and open communication with hearing health professionals are critical steps for those with such conditions to maintain their overall health, including hearing health.

Environmental Factors

Beyond loud noises, other environmental factors can influence hearing health. Prolonged exposure to chemicals, such as solvents or heavy metals, can damage the auditory system. Known as ototoxic substances, these chemicals may be encountered in specific industries or through improper handling of hazardous materials.

Minimizing exposure and following safety protocols in the workplace are important for reducing the risk of environmentally induced hearing loss. Employers and workers alike benefit from prioritizing protective measures in potentially hazardous environments.

The Role of Regular Hearing Health Exams

Addressing acquired hearing loss starts with early detection. Regular hearing health exams allow hearing health professionals to assess hearing abilities, identify changes, and recommend appropriate interventions. These exams can also provide critical insights into risks posed by occupational or lifestyle factors. Contact us today to schedule an appointment!
