Less noise in the workplace, fewer ear infections, and fewer smokers are probably the reasons why people have better hearing today, according to a new study.

A study published by the National Institute of Public Health (FHI) in 2020 showed that older people have better hearing now than 20 years ago. 

Now we know more about the reasons behind these developments. In a new study published in BMC Public Health, the FHI noted that the improvement might be due to three main factors. 

Less exposure to noise in the workplace is a particularly important reason for the improvement among men, while for women, there are fewer ear infections. 

That may be due to advances in living standards, better hygiene, the introduction of antibiotics, and improvements in health care and treatment. But less smoking also plays a role, according to FHI researcher Bo Engdahl.

A total of 65,000 people participated in the study. The FHI used figures from the Health Survey in Trøndelag (HUNT) where the population’s hearing was mapped at 20-year intervals.
