Hearing Loss: Types, Symptoms, Causes & Treatment

Hearing loss, also called hearing impairment or hearing disability, affects millions of people worldwide, from mild to profound, and impacts various aspects of daily communication and quality of life. Understanding what hearing loss is, its causes, signs, diagnosis, and prevention will help better manage hearing health.

What is Hearing Loss?

Hearing loss is the partial or complete inability to hear sounds in one or both ears. Although the condition is often associated with old age, hearing impairment can strike at any age and can be temporary or permanent. In fact, globally, about 5% of people, or approximately 430 million individuals, experience some form of hearing disability, which underlines how widespread this condition is.

Types of Hearing Loss

Primarily, there are three types of hearing loss, each with different causes and treatments.

  1. Conductive Hearing Loss: Such hearing loss involves the outer or middle ear. It is usually the result of blockages, including earwax or physical issues. Conductive hearing loss is often temporary and even curable through medical and sometimes surgical means.
  2. Sensorineural Hearing Loss: This accounts for the majority of SNHL, whereby the damage arises from either the inner ear (cochlea) or the auditory nerve. This kind of hearing loss causes difficulty hearing in loud environments.
  3. Mixed Hearing Loss: This form combines conductive and sensorineural hearing loss, where the issues lie in both the outer/middle and inner ear.

Additionally, Auditory Neuropathy Spectrum Disorder (ANSD) is a less common form where sounds reach the ear normally, but signals aren’t transmitted efficiently to the brain.

Signs and Symptoms of Hearing Loss

Recognizing the early signs of hearing problems would lead to prompt treatment and effective management of hearing health.

<H3> What Are Hearing Loss Symptoms?

The symptoms of hearing loss vary slightly depending on the severity and type. Key hearing loss symptoms include:

  • Dull or cloudy hearing: Sounds, especially speech, are muffled or indistinct.
  • Difficulty understanding conversations: In noisy areas, it becomes difficult to differentiate words.
  • Frequent requests to repeat: Asking others to repeat themselves more often.
  • Volume surge: Turning up the volume on the television or radio frequently.
  • Ringing or buzzing in the ears (tinnitus): This is among the common incidental symptoms of hearing loss.

When to See a Doctor

If the hearing loss continues or worsens, it’s best to see an audiologist or an ENT specialist for hearing loss treatment. In fact, almost any form of deafness can be dealt with very effectively if treated in time.

Causes of Hearing Loss and Deafness

Knowing the causes of hearing impairment will help prevent or manage hearing loss effectively.

  • Aging: Gradual hearing loss associated with aging is also known as presbycusis; it affects many adults as they age.
  • Exposure to Loud Noises:  This kind of exposure can impair the sensitive hair cells within the ear and cause hearing loss. According to the WHO, unsafe listening behaviors with headphones leave more than 1 billion young adults at risk for hearing loss.
  • Genetics: A few types of hearing loss are inherited, so a family history also puts an individual at risk.
  • Health Conditions: Chronic conditions like diabetes, high blood pressure, and infections, like meningitis, can disrupt the blood supply to the ear or damage nerves and cause hearing loss.

Ototoxic Medications: Some medications, including specific antibiotics and chemotherapy drugs, can damage the inner ear.

 What Are the Complications Associated with Hearing Loss?

Hearing disability can bring about many life-altering complications if not treated on time.

  • Social Isolation: Individuals tend to become socially alienated because they cannot hear and communicate well.
  • Cognitive Decline: Studies have shown that the risk of cognitive decline, as well as dementia, is higher in older adults with untreated hearing loss.

Emotional Impact: Struggling with hearing can lead to frustration, depression, and anxiety.

Diagnosis and Tests

How is Hearing Loss Diagnosed?

A combination of tests performed by an audiologist leads to the diagnosis of hearing disability.

  • Physical Examination: A doctor will check for an obstruction or other type of physical damage within the ear.
  • Pure-tone audiometry: It is the most commonly used test for hearing loss. It involves playing sounds at different frequencies measured in decibels to check how quiet a person can hear.
  • Speech Testing: Testing speech at various levels, including noisy environments.

What Are the Stages of Hearing Loss?

The stages of hearing loss can be detected based on hearing abilities:

  1. Mild: Problem in hearing soft sounds, especially in noisy surroundings.
  2. Moderate: Unable to hear comfortably without loud sounds.
  3. Severe: Hearing is only possible with very loud sounds.

Profound: Only Extremely loud sounds are audible, and communication without assistance is very difficult.

Hearing Loss Treatment, Management, and Prevention

What are the Treatment Options for Hearing Loss?

The most common hearing loss treatments are as follows:

  • Hearing Aids:  These hearing aids amplify sounds and are usually beneficial for individuals with mild to severe hearing loss.
  • Cochlear Implants: For profound hearing loss patients, implantable devices bypass damaged segments of the ear to directly make signals to the auditory nerves.
  • Assistive Listening Devices: Amplified telephones, audio induction loops, personal FM systems, etc., can facilitate hearing in noisy environments where people are unable to distinguish speech. 

Living with Hearing Loss and Deafness

Living with hearing loss is indeed challenging, but coping is within our capabilities.

  • Communication Strategies: Making the conversation easy includes facing the speaker, minimizing background noise, and using visual cues.

Support Networks: Support groups can help individuals with both resources and emotional support.

How Can I Prevent Hearing Loss?

With a few mindful steps, hearing loss prevention is possible.

  • To prevent excess noise from damaging your ears, use earplugs in lousy environments. Also, you should always use headphones at medium volumes.
  • Through regular check-ups, changes in hearing can be detected early to prevent severe complications.

Avoid smoking and poor habits, manage chronic conditions like diabetes, and clean your ears regularly to prevent hearing loss.
