Infants

Parents can have their newborns’ hearing tested quickly and easily in fact, the screening can happen moments after birth, as soon as the baby’s ears are cleared. It’s something that might not be on the radar for new parents, but this preventative step can significantly improve communication outcomes for little ones. Dr. Steve Aiken, associate professor in the School of Communication Sciences & Disorders, says all babies should have their hearing tested, and as soon as possible.
“Babies’ ears can be test in a very easy, non-invasive way,” says Dr. Aiken. “Healthy infant ears actually emit sounds in response to other sounds, called otoacoustic emissions. We use a special, tiny earphone with a microphone, play a sound and we can record if a sound comes back. The equipment is not expensive, and nurses can do it right in the hospital.”

Detection of hearing loss

Dr. Aiken says early detection of hearing loss can create better educational outcomes; also ensure that there is a proper technical intervention early on if need, like hearing aids. If there is an issue, this early intervention is critical in avoiding language delays and providing support; so whether through speech or sign language,” they says. The earlier a hearing problem is detect the better.

May is Speech and Hearing Month in Canada; so a time to highlight the importance of early detection and intervention for hearing and communication disorders. Nova Scotia is one of the provinces providing comprehensive early hearing detection and intervention services to infants. Over 96% of Nova Scotia babies are screen in this way; so earning our province a passing grade on a national report card assessing infant hearing services.

Dr. Aiken was instrumental in creating the Canadian Infant Hearing Task Force (CIHTF); which they chair until last year. The CIHTF advocates for early hearing detection and intervention programs (EHDI) in all Canadian provinces and territories. Its last full report card was issue in 2014, with a progress report issue in 2016.

Intervention services for infants

Nova Scotia earn a grade of “sufficient” on this national assessment; so as one of the provinces delivering comprehensive early hearing screening and intervention services for infants. Canada did not fare as well, receiving an ‘insufficient’ grade on the 2019 Report Card on Canadian Early Hearing Detection and Intervention Programs. A key factor in Canada’s poor result was inconsistency in delivering a universal standard of hearing screening and intervention services for infants across the country.
Your postal code shouldn’t determine access to services for newborn and infant hearing loss,” says Dr. Aiken. The 2019 report card detail “an alarming disparity” in the hearing health services available to infants and children in Canada, and reveal little has change since the CIHTF’s last full report in 2014.
The group of audiology experts aims to raise awareness and advocate for comprehensive EHDI programs across Canada. They also developed a change.org petition that was read in the House of Commons, calling on the federal government to show some leadership in this area at the policy level.
