More than 90 students were tested by the Hear Our Heart Ear Bus yesterday on the school grounds.

Principal Eileen Day was amazed with the response the program had received so far, with a waiting list already beginning for the next ear testing session at the school.

"It's been an absolutely amazing response as we've been able to screen children in pre-school all the way through to year 6 students," Mrs Day said.

The Hear Our Hear Ear Bus is the first mobile children's ear clinic in NSW.

The bus is on a mission to increase the awareness of otitis media, often referred to as glue ear, and the importance of ear health throughout NSW.

Itinerant Support Teacher with Hearing in the Western NSW region Rachel Mills believes this program is way of informing parents of things they may be unaware of.

Students have been undergoing educational sessions on blowing their noses to improve their hearing, which is a common issue according to Ms Mills.

"We've been able to inform parents of issues with their children's hearing which they were previously unaware of," Ms Mills said.

"Poor behaviour is often misdiagnosed as ADHD when in fact it is directly related to middle ear problems."

Audiologist Jocelyn Ho was conducting the hearing screen tests on the students.

"We need to create awareness in rural areas where there are a lack of resources," she said.

Hear Our Heart Ear Bus Project is an initiative on behalf of the Dubbo District Support Group for the Deaf and Hearing Impaired Inc, local charity established in 1997.
