What is sensorineural hearing loss? The condition Alka Yagnik opened up about

For many people, the term sensorineural hearing loss became familiar after singer Alka Yagnik spoke about her condition while receiving the Padma Bhushan. The legendary playback singer revealed that she developed a rare form of hearing loss following a viral infection, which affected her hearing and forced her to take a break from work.

Her story sparked curiosity about a condition that many people know little about. 
So, what exactly is sensorineural hearing loss?

Sensorineural hearing loss occurs when there is damage to the inner ear or the auditory nerve, which carries sound signals from the ear to the brain.

Inside the inner ear is a structure called the cochlea. It contains tiny hair cells that convert sound vibrations into electrical signals. These signals are then sent to the brain, which interprets them as sound.

When these delicate hair cells become damaged, or when the auditory nerve is affected, sounds may become softer, distorted or difficult to understand.

Unlike some forms of hearing loss caused by earwax, infections or blockages, sensorineural hearing loss is usually permanent because damaged hair cells in the inner ear do not regenerate naturally.

Why does it happen?

There is no single cause.

One of the most common reasons is ageing. As people grow older, the inner ear naturally undergoes wear and tear. This age-related hearing loss is known as presbycusis.

However, age is far from the only factor.

Long-term exposure to loud noise can damage the sensitive structures inside the ear. This may include years of working in noisy environments, attending loud events, listening to music at high volumes through earphones or repeated exposure to machinery and traffic noise.

Other possible causes include certain viral infections, head injuries, genetic conditions, some medications known to affect hearing, and medical conditions that impact blood flow to the inner ear.

In some cases, hearing loss may occur suddenly and require urgent medical attention.

The signs are often easy to miss

Many people assume hearing loss means complete silence or severe deafness. In reality, sensorineural hearing loss often develops gradually.

One of the earliest signs is difficulty understanding speech, especially in noisy environments.

You may hear that someone is talking but struggle to make out the words clearly. Restaurants, family gatherings, weddings and busy offices can become particularly challenging.

People with the condition often find themselves asking others to repeat what they said.

Other common symptoms include:

• Frequently increasing the television or mobile phone volume.
• Difficulty hearing high-pitched sounds.
• Feeling that people are mumbling when they speak.
• Trouble following group conversations.
• Ringing, buzzing or humming sounds in the ears, a condition known as tinnitus.
• Difficulty understanding speech over the phone.

Because the changes are often gradual, family members sometimes notice the problem before the affected person does.

Why conversations become so difficult

One of the most frustrating aspects of sensorineural hearing loss is that it does not simply reduce volume.

Many people can still hear sounds but struggle to understand speech clearly.

Imagine listening to a conversation where some letters or syllables are missing. The sound reaches your ears, but the brain does not receive a complete signal.

This is why people with hearing loss often say, "I can hear you, but I can't understand what you're saying."

Background noise can make this problem much worse.

It can affect more than hearing

Hearing loss is often thought of as an ear problem, but its impact can extend far beyond hearing itself.

Communication difficulties can affect confidence and social interactions. Some people begin avoiding gatherings because conversations become exhausting or embarrassing.

Others may feel isolated when they struggle to keep up with discussions among friends, family or colleagues.

Research has also found links between untreated hearing loss and reduced quality of life, social isolation and increased cognitive strain, as the brain works harder to process sounds.

When should you see a doctor?

Any noticeable change in hearing should be evaluated by a healthcare professional.

Sudden hearing loss, particularly if it occurs over hours or days, is considered a medical emergency and should be assessed as quickly as possible.

Even gradual hearing difficulties deserve attention, especially if they are affecting work, communication or daily activities.

An ear, nose and throat (ENT) specialist or audiologist can perform hearing tests to identify the type and severity of hearing loss.

Can it be treated?

The treatment depends on the cause and severity of the condition.

While damaged inner-ear hair cells generally cannot be restored, many people benefit significantly from hearing aids. Modern hearing aids are much smaller and more advanced than older devices, helping amplify sounds and improve speech clarity.

For severe cases, cochlear implants may be considered. These devices bypass damaged parts of the inner ear and directly stimulate the auditory nerve.

The earlier hearing problems are identified, the more options are typically available for managing them effectively.

Can you protect your hearing?

Not all cases of sensorineural hearing loss can be prevented, but certain steps can reduce the risk.

Keeping the volume at safe levels when using earphones or headphones is important. Health experts generally recommend avoiding prolonged exposure to loud sounds and taking listening breaks when using personal audio devices.

People who work in noisy environments should use appropriate hearing protection such as earplugs or earmuffs.

Regular hearing check-ups may also be helpful, particularly for older adults or those with a history of noise exposure.

Sensorineural hearing loss is one of the most common forms of hearing loss, yet many people do not recognise the symptoms until everyday conversations become a struggle.

It is not always about hearing less. Often, it is about hearing differently.

The good news is that early diagnosis and appropriate treatment can make a significant difference.
