Overview

Hearing is one of the most important senses which allows us to perceive our surroundings, communicate, create connections, learn, and enjoy meaningful activities. Hearing loss is a prevalent condition that impacts millions of individuals worldwide. The World Health Organization (WHO) reports that over 1.5 billion people – or 1 in 5 of the global population – experience it in some form. This condition is characterized by a diminished ability to hear clearly, resulting in challenges in understanding speech and engaging in conversations.

The instances of hearing loss rises significantly with age, affecting 25% of individuals over the age of 60 and 50% for those over 75. If you’d like to see more statistics on the prevalence of hearing loss, you can find them here: https://journals.lww.com/ear-hearing/fulltext/2024/01000/hearing_loss_prevalence,_years_lived_with.24.aspx

Ultimately, untreated hearing loss affects quality of life, often leading to isolation. It has been associated with serious conditions such as depression, anxiety, dementia, and reduced mobility.

Hearing loss can result from various factors. What are the common causes?
• Ageing – The natural aging process can lead to a gradual decline in hearing sensitivity. It typically begins around age 50 and affects high frequency sounds. It manifests in difficulties understanding speech in noisy environments.
• Noise exposure – Prolonged exposure to loud noises, such as loud music or machinery, can damage the structures of the ear, resulting in hearing loss.
• Medical conditions – Some medical conditions like ear infections or ear-specific diseases can contribute to hearing loss.
• Genetics – Genetic factors can also play a significant role in hearing loss, usually for severe or profound hearing loss.

Usually, the first signs of hearing loss are difficulties understanding speech in challenging situations, such as speaking with multiple people or in environments with a lot of background noise, like crowded restaurants. Other symptoms may be perceiving speech as mumbled or too fast, needing to ask for repetitions, and complaints from family members.
People close to you will often notice your hearing loss before you do. Hearing loss may also cause listening effort – the feeling that you have to strain to understand speech and that conversations cause fatigue.
Consult a health provider when you notice one or more of these symptoms. They may recommend an ENT exam to check the physical condition of the ears and get a referral for a professional diagnostic hearing test, performed by an Audiologist.

A hearing test, or audiometry, measures the softest sounds a person can hear in different tones and in speech sounds. During this test you may hear very soft pure tone sounds, ranging from low frequencies (bass) to high frequencies (treble). You may be asked to signal when you hear them. You should initially hear the sounds via air-conduction headphones to determine the threshold of hearing. Then, if hearing loss is detected, the sounds could be delivered via a bone-conduction transducer to locate the site of the damage in the auditory system. The hearing test may also incorporate speech reception tests, which indicate the softest speech sounds you can hear, and word recognition (or discrimination) tests. Here, speech may be presented at a comfortable level, and the Audiologist could measure how many sounds you can hear clearly.
The outcome of the test may be an Audiogram, a visual depiction of your hearing capability. The graph specifies the hearing threshold for different frequencies for the right and left ear. An audiologist can interpret these results and determine the existence, degree, type, and shape of your hearing loss.

There are three types of hearing loss, depending on the location of the damage. These types differ in their causes and treatment options.
Sensorineural hearing loss is the most common and is generally caused by damage to the inner ear (cochlea) or to the nerve pathways to the brain. Common causes include ageing, exposure to loud noise, and certain medical conditions. Sensorineural hearing loss is usually permanent and cannot be medically or surgically corrected. Hearing aids can usually help with this kind of hearing loss.
Conductive hearing loss occurs when sound is not conducted efficiently through the outer and middle ear. Possible causes are ear infections, earwax blockage, fluid in the middle ear, or a punctured eardrum. If you think you may have conductive hearing loss, we recommend you see a doctor, as this type of hearing loss can often be temporary or medically corrected.
Mixed hearing loss is a combination of sensorineural and conductive components.

If you have any of the problems listed below, please see a doctor who may refer you to an (ENT):
•   Your ear has a birth defect or an unusual shape
•   Your ear was injured or deformed in an accident
•   You saw blood, pus, or fluid coming out of your ear in the past 6 months
•   Your ear feels painful or uncomfortable
•   You have a buildup of earwax, or you think something could be in your ear
•   You get dizzy or you have a feeling of spinning or swaying (called vertigo)
•   Your hearing changed suddenly in the past 6 months
•   Your hearing changes: it gets worse then gets better again
•   You have worse hearing in one ear
•   You hear ringing or buzzing in only one ear.

A very common complaint of hearing aid users is that they have difficulty understanding speech in noisy surroundings, even while wearing their hearing aids. 
Our discreet solution is easy to use and allows you to amplify your preferred sound source when facing it, enhancing it over the background noise, when using the Frontal mode which uses beamforming directional microphones. 
One of the most effective ways to improve speech understanding in noisy environments is to separate the speaker you want to listen to and the rest of the environment.
