The bus will be in Narromine at Council Parking 124 Dandaloo Street on Friday from 9am.

The service provides more than 28,000 free hearing checks in communities across Australia since it first launched in 2009.

Debra Amos manager at Australian Hearing Dubbo said as age-related hearing loss developed gradually over time it was common for people to not be aware their hearing was diminishing.

Hearing loss is a prevalent issue in the community with about 60 per cent of Australians over 60 suffering from some form of hearing loss.

As well as having a hearing check, visitors to the bus can find information on a range of common hearing issues and view a display of easy-to-use hearing devices for around the home.

This includes headsets for watching the TV and alert systems for doorbells.

No appointment is necessary.

Australian Hearing will provide hearing checks to any interested adults who visit the bus on the day.
