Hearing Loss: A Growing Public Health Problem

Hearing loss is on the rise, and a growing body of evidence shows that this has implications for your overall health.

Many of us assume that hearing loss is just a natural part of aging. In fact, it is a public health problem that spans all age groups.

It’s also on the rise. The world is getting louder, exposing us to hazardous levels of noise that can cause sensorineural hearing loss (SNHL). Today, 15% of adults worldwide have some degree of hearing loss, and that number is expected to rise to 22% by the year 2060.1

The consequences of untreated SHNL can be costly to both individuals and society. Recent research has linked hearing loss to social isolation, depression and cognitive decline.2 It is also associated with poor health care outcomes, higher health care costs and higher unemployment rates.3

How prevalent is hearing loss?

Around the Globe

  • 720 million adults have some degree of hearing loss
  • 90% of these cases are caused by SNHL
  • Another 1.1 billion people between the ages of 12 and 35 are at risk of acquiring hearing loss, as exposure to recreational noise increases.4

In the U.S.

  • Hearing loss is the third most common chronic condition after hypertension and arthritis.5 It is twice as prevalent as diabetes or cancer.6
  • As of 2020, about 40 million have SNHL, and that number is expected to grow to 48 million by 2030.
  • 22 million people are exposed to hazardous noise in the workplace, putting them at risk of SNHL.7
  • 1 in 8 children ages 6-19 already have hearing loss in one or both ears caused by exposure to hazardous noise, such as loud music.8

A Growing Public Health Problem

Hearing loss and your overall health

Hearing loss increases an individual’s risk of other health conditions, such as:

  • Clinical depression
  • Dementia, including Alzheimer’s disease, and other types of cognitive decline
  • Falls and associated injuries, which can be fatal in the elderly9

Individuals with hearing loss make more visits to the emergency room, and have more frequent and longer hospital stays.3

Untreated hearing loss also results in poorer healthcare outcomes overall, possibly because it is more difficult for healthcare providers to communicate effectively with patients who don’t hear clearly.

These healthcare issues translate into higher medical expenses for people with hearing loss – to the tune of an extra $22,434 over a ten-year period.10

Social and economic impact beyond healthcare

  • Untreated hearing loss interferes with daily social interactions, leading to social isolation and feelings of frustration and loneliness. These can all contribute to a poorer quality of life.
  • Adults with hearing loss have a higher unemployment rate, which reduces their income and ability to afford healthcare.
  • Adults with hearing loss who are employed tend to have lower-grade jobs.
  • Children with even mild hearing loss may miss up to 50% of classroom discussions, which has negative consequences for their education and future.
  • The World Health Organization (WHO) estimates the global cost of untreated hearing loss is $750 billion annually in terms of the negative impacts on productivity, healthcare, education and society.
