Hearing Loss Statistics
Research indicates that these statistics apply to most countries. These are from Australia, all you need to do to is multiply the percentage by your country’s population to find the number of people.
- There are 3.5 million people in Australia with a hearing loss 16.67% of population
- 60% or 2.1million of these are males mostly due to industrial deafness
- 37% or 1.295million are over 70 years of age
- 66% or 2.31 million have a mild loss which results in personal communication difficulty
- 23% or 0.8 million have a moderate loss which usually means they need a hearing aid
- 11% or 39,000 people have a severe or profound loss for whom hearing aids cannot help and are likely to benefit from a Cochlear Implant
Age of people with hearing loss
- 1 in 6 Australians suffer from some kind of hearing loss
- As the baby boomers age this prevelance is expected to increase to 1 in 4 of all Australians
- For those over 50 years of age this is 1 in 4
- Over 70 and this rises to 3 in 4
- 6 in 10 over the age of 60 within 30 years
- Nearly half of those with a hearing loss are working age (15-64)
- Employment rates for hearing impaired people are lower than for the rest of the population 20.5% lower for men and 16.5% lower for women
Noise is more than annoyance
- 10dcbl is the level of sound of rustling paper
- 30dcbl is the sound of a watch ticking
- 50dcbls is the level required to hear quiet conversation
- 60dcbls is needed for normal conversation
- 70 to 80dcbls is the level of traffic noise (tram)
- To hear above the noise of a tram you would need to have your iPod or MP3 player at 80dcbls
- Every 6dcbls is 100% amplification. Therefore to raise your level of sound to 80dscbls means you’ve amplified the volume 20dcbls over normal conversation or more than 300%
Wearing hearing aids
- Only 1 in 3 people who could use a hearing aid do.
- There is an average of 6 years between when they need help with hearing and when they actually seek help.
