But what does the 'Quiet Hour' actually entail?
Changes customers will notice during the listed times include Coles Radio turned down to the lowest volume, reduced register and scanner volume, and no use of the in-store PA system (apart from in emergencies).
Head of Diversity and Inclusion at Coles, Katie Wyatt said the decision to give 'Quiet Hour' a more permanent place was an easy one for the grocery giant to come by.
"At Coles, we are always looking for new ways to serve our customers with disabilities and their careers, and we are privileged to have many active voices of people with disability in our feedback channels," she shared with New Idea.
"Up to 70% of autistic people experience sensitivity to sounds, with autistic adults reporting that these symptoms worsen with stress and anxiety, therefore, Quiet Hour promotes increased opportunity and enhances the shopping experience for thousands of customers."
