Hearing helps us keep relationships with those we love

It doesn't take much hearing loss to make communication difficult and to interfere with the way we interact with other people. It can affect our closest personal relationships, our professional relationships, and even our daily routines. Healthy hearing is a really important part of cur connection with others, and without it, it’s easy to feel isolated or left out of normal life.

Hearing is a delicate balancing act in which mechanisms of the inner ear and brain work together in interpreting sound. Problems with either the inner, middle, or outer ear can prevent important sound information from reaching the brain; such partial information can be a source of confusion and misunderstanding of what is being said.

These misunderstandings are why loss of hearing has such a big impact on us, and on our relationships. It's frustrating and disheartening to constantly experience miscommunication.

A basic understanding of hearing loss is a good thing to have to help us take care of our own hearing health, and to support those around us who may be experiencing difficulty hearing.

Ear problems involving the middle ear are often associated to conductive hearing loss. Problems related to the inner ear or the ability of the brain to process sound information are often sensorineural hearing loss. These are two distinct types of hearing loss with differing treatment methods.

01 | Understanding why healthy hearing matters so much

Communication is not just the words people choose to use. How we speak, our words, and the tone of our voice all work together to express our thoughts and feelings. A voice can he deeply moving, conveying thoughts, emotions, and feelings.

Every spoken word consists of sounds and tones which create understanding and enable us to build and maintain relationships. When we or our loved ones are missing portions of this communication, they are missing the chance to hear, understand, and connect with us.

02 | Hearing equals participating

Hearing and understanding provide a vital link to the world around you. They enable you to communicate and Interact with others and are a source of enjoyment and information. The sense of hearing is often taken for granted and its gradual deterioration can impact your ability to actively participate in life.

03 | The impact of hearing loss

If you have a loss of hearing, you probably are having to put in more effort to hear and understand. Having to do this constantly can be tiring, and you may find yourself withdrawing from social activities because of this extra strain. It's common to discover that people with hearing loss have been carefully arranging their lives to avoid difficult or frustrating situations where their hearing loss is interfering with life.

"... you may find yourself withdrawing from social activities because of this extra strain. its common to discover that people with hearing loss have been carefully arranging their lives to avoid difficult or frustrating situations..."

Hearing loss also affects the people around you. Conversations and interactions can become more strenuous, not only for you but also for them. Communication breakdown is stressful for everyone, and over the long term, can cause real hardship. Studies show that people who took steps to address their hearing loss experience a noticeable improvement in many aspects of their lives.

04 | When voices become less clear

Hearing loss can creep up gradually, without you realizing it at first. Same sounds remain audible while others become softer and harder to hear. As a result, communication becomes increasingly challenging and requires more effort. It is the higher pitched sounds that are often hardest to hear and understand. High-pitched consonants like "s","f and ,h" play a key role in our ability to understand speech clearly. This is why people with a hearing loss often say "I can hear, but I don't understand what's being sad" or think people around them are mumbling.

05 | Hearing loss affects individuals and everyone around them

Hearing loss is a widespread problem that can affect not only individuals but also their families and communities. In Canada, 37% of the population experiences hearing loss, often due to aging or exposure to loud noise. The gradual onset of hearing loss can make it difficult for people to notice changes in their hearing, In fact, 77% of Canadians with hearing loss do not realize they have a problem. Although hearing loss can affect people of any age, it is more common in those over 50 and is a leading chronic condition, more prevalent than diabetes or cancer. Despite its gradual and invisible nature, hearing loss can have a significant impact on a person's life and the people around them.

06 | How healthy hearing works

How we hear

How We Hear

When a sound enters the outer ear, it causes the eardrum to vibrate. The sound is transmitted by three small bones from the middle to the inner ear. The inner ear contains a snail-like shaped structure called the cochlea which is filled with fluid and lined with sensory cells with microscopic fine hairs. These hairs move with the vibrations and convert the sound waves into nerve impulses which are sent to the brain. The result is the sound you hear.

Binaural Hearing​

Binaural Hearing

The Preferred Method The brain, ability to process information from both ears at once is called "binaural hearing." This perfect situation is great for communication. It lets us understand sound clearly, identify exactly where it's coming from and even pick out the sounds we want to hear when they're competing with other sounds in noisy environments.

When one ear lags behind the other in hearing ability, the condition is called "unilateral hearing loss, People in this situation comprehend only about 30 to 35 percent of what two healthy ears can hear. Unilateral hearing loss can be especially tough on students. For instance, being forced to repeat a grade is much more likely for a child with a poorly functioning ear.

07 | Common causes of hearing loss

Common causes of hearing loss include genetics, damage to some portion of the inner ear, middle ear, or outer ear, and loud noise. Hearing health can also be affected by other conditions like diabetes, cardiovascular disease, ototoxic medications from cancer or smoking.

The outer ear

Typical conditions which may lead to hearing loss Include excessive accumulation of earwax and infections of the ear canal.

The middle ear

Perforation of the eardrum, ear infection, or fluid in the middle ear are the most common causes of hearing loss in the middle ear. Many outer and middle ear problems can be treated by a doctor. Hearing loss caused by conditions of the outer or middle ear is referred to as a conductive hearing loss.

The inner ear

The majority of hearing problems result from damage to the inner ear. Typical causes are the natural aging process, medication that is toxic to the auditory system, and head injury. Excessive exposure to noise is another common cause of hearing lass. Generally, hearing loss resulting from inner ear damage cannot be reversed by medical treatment, but can largely be improved with hearing aids. This type of hearing loss is referred to as a sensorineural hearing loss.

10 | Common types of hearing loss

Sensorineural Hearing Loss (SHL)

This most common type of hearing loss tends to result from damage to delicate hair cells in the cochlea located in the inner ear; those cells are responsible for picking up sounds. Over exposure to loud noises can damage or destroy these cells—or the nerves they connect to—making hearing more difficult. High-frequency sound is usually the first casualty of loud-noise exposure, which can lead to permanent high-frequency hearing loss.

Conductive Hearing Loss

Infection or blockage of the outer or middle ear tends to be the culprit in this type of hearing loss. Middle-ear infections (otitis media) can cause sound-blocking fluid build-ups. A blockage outside the eardrum can he caused by swimmer, ear or a buildup of earwax. Conductive Hearing Loss is typically treatable, subsiding once the infection or blockage clears, or as the result of needed surgery.

Mixed Hearing Loss

This condition tends to involve some combination of sensorineural hearing loss (SHL) and semi-permanent conductive hearing loss, perhaps an ossicle malfunction in the middle ear (ossicles are tiny bones that conduct sound). Once the conductive hearing loss has been handled through treatment or surgery, hearing should improve; the SHL, however, tends to be permanent.

"Overexposure to loud noises can damage or destroy these cells—or the nerves they connect to—making hearing more difficult. High-frequency sound is usually the first casualty of loud-noise exposure, which can lead to permanent high frequency hearing loss."

Unilateral Hearing Loss

This term refers to hearing loss in only one ear. A person can be born with it, it can come on spontaneously and even over the cease of several days. In early life, it can interfere with speech and language development; children may also have trouble understanding where sounds are coming from, hearing speech in noisy situations, and hearing at longer distances. A focus on communication development can help kids born with unilateral hearing loss achieve academic, economic and social success.

Sudden Hearing Loss

Just as the name suggests, this is a sudden loss in hearing, either total or partial, either immediately or over a 24-hour period. Sudden hearing loss tends to self-resolve within two weeks, but the possibility of permanent hearing loss exists. Steroids may he used to support hearing recovery, but when there is no positive change within two weeks, improvement is unlikely. Immediate treatment greatly Increases the chances of a full recovery, and about 85 percent of people who seek treatment will get some of their hearing back; so, if sudden hearing loss occurs, consult your physician right away.

The only way to accurately evaluate the condition of your bearing is with a professionally administered test that assesses your ability to hear an entire range of sound.

High-Frequency Hearing Loss

In cases of high-frequency hearing loss, vowels tend to come through clearly, where consonants like f, s, t, and z are hard to understand. Since it develops slowly over the course of decades, diagnosing high-frequency hearing loss tends to he difficult. Early signs of it include trouble hearing higher-octave sounds, like chirping birds, or the voices of women and small children. It can also be indicated by difficulty conversing in groups or hearing speech amid background noise. Hearing aids are an effective treatment for high-frequency hearing loss, but wearing hearing protection when you're exposed to loud noises can go a long way toward preventing it in the first place.
