Hearing loss is usually discussed in terms of health, communication and quality of life. But new Australian research shows it also carries a significant and long-term financial cost.
A recent study from Macquarie University and the University of Sydney using nearly two decades of national data has found when Australians develop hearing loss, their earnings and income decline and stay lower for years.
"What stands out is that these effects don't fade over time. Earnings and income remain lower for many years, showing the impact is persistent rather than temporary," said Dr Mohammad Nure Alam, a Postdoctoral Research Fellow in Health Economics.
What did the research look at?
The study from the Hearing Research Centre analysed data from the Household, Income and Labour Dynamics in Australia survey. Researchers followed working-age adults aged individuals for up to 19 years, comparing those who developed hearing loss with similar people who did not.
This approach made it possible to examine what happens not just after hearing loss begins, but also in the years before and long after its onset.
What happens to earnings?
The findings show a clear and sustained impact on earnings and income.
Within five years of developing hearing loss, earnings fall by around 16 to 17 per cent. Over time, the gap grows larger. Fifteen years after onset, earnings remain significantly lower than they would otherwise have been, with losses approaching 30 per cent in some cases.
Income, which includes other sources beyond wages, also declines. The drop is slightly smaller than for earnings, suggesting some people offset losses through other income streams. Even so, the overall financial impact remains substantial.
"While our study does not directly test the reasons, the growing impact over time likely reflects a combination of factors. Hearing loss can make communication at work more difficult, which may affect job performance, progression and opportunities," Dr Nure Alam says. "Over time, these challenges can build, leading to larger and more persistent gaps in earnings and income."
Hearing loss tends to amplify existing inequality.
Who is most affected?
The effects are not evenly shared. Hearing loss tends to amplify existing inequalities.
People from lower socioeconomic backgrounds experience larger and more persistent income losses than those in more advantaged areas. Individuals with lower levels of education are also more affected than those with higher qualifications.
Younger Australians are particularly vulnerable. Those in the early stages of their careers can experience significant long-term losses, as hearing loss disrupts career progression and limits opportunities.
There are also gender differences. Men tend to experience larger and more sustained declines in earnings following the onset of hearing loss.
"Hearing loss doesn't affect everyone equally. The financial effects are larger and more persistent for people from lower socioeconomic backgrounds," said Dr Nure Alam.
Why does hearing loss affect income?
Hearing loss can make communication more difficult at work, affect productivity and limit access to certain roles. It can also reduce opportunities for promotion and increase the likelihood of moving into lower-paid or less secure jobs.
Over time, these effects build, leading to a widening gap between people with hearing loss and their peers.
What does this mean for Australians?
The findings suggest hearing loss is not just a health issue but an economic one.
In Australia, hearing services are well supported for children and older adults. But many working-age Australians fall through the gaps, especially those who are employed but not eligible for government assistance.
This raises questions about whether current policies are addressing the needs of people when hearing loss begins to affect their working lives.
"While services are available for children and older Australians, many working-aged people may not have access at the time they need it. Improving access could help reduce the longer-term financial impact of hearing loss," says Dr Nure Alam.
The bottom line
Hearing loss can have a lasting financial impact that extends well beyond diagnosis. For many Australians, it means lower earnings, reduced income and fewer opportunities over time.
Understanding that cost is an important step towards better support and more effective policy responses.
