WHAT IS THE RELATIONSHIP BETWEEN EXTREME POVERTY, IMPAIRED HEARING & MUSIC?
Join us as a GC VIP and let’s support the Global Citizens Festival.
IS THERE A RELATIONSHIP BETWEEN EXTREME POVERTY, IMPAIRED HEARING & MUSIC?
THE ANSWER IS YES.
Statistically speaking, hearing loss is related to poverty and children born into poverty have a greater risk of hearing loss.
There are numerous causes of hearing loss, some of which are more likely to be associated with poverty. According to the World Health Organization, lack of prenatal care can lead to hearing loss in infants.
Mothers who have certain infections, including rubella or syphilis, are more likely to give birth to infants with hearing loss. Mothers who do not have access to prenatal care are more likely to give birth to premature infants or infants with low birth weight, both of which are possible causes of pregnancy.
In addition, lack of access to prenatal care can also lead to complications during delivery. Infants experiencing a lack of oxygen immediately after birth (known as birth asphyxia) are at a higher risk of hearing loss.
Ways Music Can Lift People Out of Extreme Poverty includes studying and playing music as this has proven to affect more than just literacy skills.
Studies have observed that individuals who learn how to play music experience increased self-esteem, they believe that they can achieve things that they never thought possible.
By 2050 nearly 2.5 billion people are projected to have some degree of hearing loss and at least 700 million will require hearing rehabilitation.
Over 1 billion young adults are at risk of permanent, avoidable hearing loss due to unsafe listening practices.
An annual additional investment of less than US$ 1.40 per person is needed to scale up ear and hearing care services globally.
Over a 10-year period, this promises a return of nearly US$ 16 for every US dollar invested.

THE ANSWER IS YES.
Statistically speaking, hearing loss is related to poverty and children born into poverty have a greater risk of hearing loss.
It is estimated that by 2050 over 700 million people – or 1 in every 10 people – will have disabling hearing loss.
‘Disabling’ hearing loss refers to hearing loss greater than 35 decibels (dB) in the better hearing ear.
Nearly 80% of people with disabling hearing loss live in low- and middle-income countries.
The prevalence of hearing loss increases with age, among those older than 60 years, over 25% are affected by disabling hearing loss.
Deafness and Hearing Loss Overview:
Over 5% of the world’s population – or 430 million people – require rehabilitation to address their disabling hearing loss (432 million adults and 34 million children)

A study at Northwestern University has proven that music can help alleviate the psychological damages that poverty brings.
People often do not put music and poverty together, but the study of music is often beneficial and may allow some the chance to escape the poverty line.
Hearing loss and deafness
A person who is not able to hear as well as someone with normal hearing – hearing thresholds of 20 dB or better in both ears – is said to have hearing loss.
Hearing loss may be mild, moderate, severe, or profound. It can affect one ear or
both ears and leads to difficulty in hearing conversational speech or loud sounds.
‘Hard of hearing’ refers to people with hearing loss ranging from mild to severe.
People who are hard of hearing usually communicate through spoken language and can benefit from hearing aids, cochlear implants, and other assistive devices as well as captioning.
‘Deaf’ people mostly have profound hearing loss, which implies very little or no hearing. They often use sign language for communication.
Causes of hearing loss and deafness
Although these factors can be encountered at different periods across the life span, individuals are most susceptible to their effects during critical periods in life.
Prenatal period
Genetic factors including hereditary and non-hereditary hearing loss
intrauterine infections – such as rubella and cytomegalovirus infection.
Perinatal period
Birth asphyxia (a lack of oxygen at the time of birth
hyperbilirubinemia (severe jaundice in the neonatal period)
low-birth weight
other perinatal morbidities and their management.
Childhood and adolescence
chronic ear infections (chronic suppurative otitis media)
collection of fluid in the ear (chronic nonsuppurative otitis media)
meningitis and other infections.
Adulthood and older age
chronic diseases
smoking
otosclerosis
age-related sensorineural degeneration
sudden sensorineural hearing loss.
Factors across the life span
cerumen impaction (impacted ear wax)
trauma to the ear or head
loud noise/loud sounds
ototoxic medicines
work related ototoxic chemicals
nutritional deficiencies
viral infections and other ear conditions
delayed onset or progressive genetic hearing loss.
The impact of unaddressed hearing loss
When unaddressed, hearing loss impacts many aspects of life at individual level:
-communication and speech
-cognition
-education and employment: In developing countries, children with hearing loss and deafness often do not receive schooling. Adults with hearing loss also have a much higher unemployment rate.
Among those who are employed, a higher percentage of people with hearing loss are in the lower grades of employment compared with the general workforce.
social isolation, loneliness and stigma impact on society and economy effects on years lived with disability (YDLs) and disability adjusted life years (DALYs).
WHO estimates that unaddressed hearing loss poses an annual global cost of US$ 980 billion.
This includes health sector costs (excluding the cost of hearing devices), costs of educational support, loss of productivity, and societal costs.
Of these costs, 57% are attributed to low- and middle-income countries.
Prevention
Many of the causes that lead to hearing loss can be avoided through public health strategies and clinical interventions implemented across the life course.
Prevention of hearing loss is essential throughout the life course, from prenatal and perinatal periods to older age. In children, nearly 60% of hearing loss is due to avoidable causes that can be prevented through implementation of public health measures.
Likewise, most common causes of hearing loss in adults, such as exposure to loud sounds and ototoxic medicines, are preventable.
Effective strategies for reducing hearing loss at different stages of the life course include:
-Immunization;
-good maternal and childcare practices;
-genetic counselling;
-identification and management of common ear conditions;
occupational hearing conservation programmes for noise and chemical exposure;
safe listening strategies for the reduction of exposure to loud sounds in recreational settings; and rational use of medicines to prevent ototoxic hearing loss.
Identification and management
Early identification of hearing loss and ear diseases is key to effective management.
This requires systematic screening for detection of hearing loss and related ear diseases in those who are most at risk. This includes:
-newborn babies and infants
-pre-school and school-age children
-people exposed to noise or chemicals at work
-people receiving ototoxic medicines
-older adults.
-Hearing assessment and ear examination can be conducted in clinical and community settings.
Tools such as the WHO “hearWHO” app and other technology-based solutions make it possible to screen for ear diseases and hearing loss with limited training and resources.
Once hearing loss is identified, it is essential that it is addressed as early as possible and in an appropriate manner, to mitigate any adverse impact.
Measures available to rehabilitate people with hearing loss include:
-the use of hearing technologies, such as hearing aids, cochlear implants and middle ear implants;
-the use of sign language and other means of sensory substitution, such as speech reading, use of print on palm or –Tadoma, signed communication; and
rehabilitative therapy to enhance perceptive skills and develop communication and linguistic abilities.
The use of hearing assistive technology, and services such as frequency modulation and loop systems, alerting devices, telecommunication devices, captioning services and sign language interpretation, can further improve access to communication and education for people with hearing loss.
