Objective
To investigate whether hearing difficulties exacerbate the damaging effects of enforced social distancing due to the COVID-19 pandemic on isolation and loneliness, and lead to accelerated mental health issues and cognitive dysfunction.

Design
Rapid online survey. Participants completed a series of online questionnaires regarding hearing ability, socialisation (pre- and during-pandemic), loneliness, anxiety, depression and cognitive function.

Study sample
A total of 80 participants over the age of 70 with access to the internet.

Results
There was a significant reduction in socialisation levels from pre-pandemic in this population. Hearing difficulties were significantly associated with greater levels of loneliness, depression and self-perceived cognitive dysfunction after controlling for age, gender, and level of education. Additionally, compared to pre-pandemic, people with hearing difficulties had increased odds of reporting worsened anxiety, depression, and memory during the COVID-19 pandemic, although only the effect of hearing difficulties on the change in memory reached statistical significance after controlling for age, gender, and level of education.

Conclusions
The worse the self-reported hearing abilities are, the greater the negative impact of enforced social distancing on depression, loneliness and cognitive function.
