Hearing and vision impairments are highly prevalent among older adults and can contribute to social isolation and loneliness. Whilst most research has focused on individual assistive device use, the role of hearing- and-vision friendly design in enabling inclusive engagement within shared environments remains under explored. This presentation reports on work combining evidence-based environmental design, resident co-design and scalable audio technology to enhance hearing- and vision-friendly communal spaces in retirement living. Following expert review of evidence-based hearing- and vision-friendly design principles for retirement living, co-design workshops were conducted with 64 residents and one manager across three villages to inform refurbishment recommendations. Concurrently, Bolton Clarke commenced the world’s largest aged care implementation of Auracast, a Bluetooth technology transmitting audio directly to headphones and hearing devices in communal spaces, across 26 villages. To evaluate the impact on wellbeing, social participation, and sensory function, measures are being collected pre/post refurbishments using the UCLA-3, Lubben Social Network Scale, Social Isolation Measure, and Vision Function Questionnaire. Baseline data have been collected at one site (n=12), with data collection ongoing. Post-intervention interviews and surveys will follow refurbishments from May. Across sites, co-design workshops revealed consistent priorities despite local differences. Residents strongly endorsed vision-friendly features (e.g. high contrast signage, clear walkways, adjustable blinds) and hearing-friendly features (e.g. noise dampening, sound absorption, reduced background noise, enhanced lighting). Collectively, this work demonstrates how inclusive environmental design and refurbishments combined with scalable audio technology can support social participation in retirement living, offering a practical and transferable model for age friendly communal spaces.
