Impacts of COVID-19 on Communication Accessibility for Adults with Hearing Loss

Earlier this year, the Canadian Hard of Hearing Association and Wavefront Centre for Communication Accessibility partnered together to conduct a survey to collect information on the impact the pandemic has had on the daily lives of people who experience hearing loss and deafness. We received close to 700 responses within the time period of when the survey was available.

The principal investigators, Dr. Brenda Poon and Dr. Lorienne Jenstad, will present the survey findings. They will discuss key findings related to communication accessibility in our day-to-day lives, such as demand for universal captioning, the impacts of masks, ways to promote clearer communication, and the accessibility of obtaining information from the government.
