Read MoreThe Convergence of Distributed Audio and Smart Building Infrastructure in Hospitality Projects
For many years, audio systems in hospitality projects were treated as isolated AV components, often added during the final stages of project delivery. Background music systems for guest rooms, restaurants, lounges, and conference spaces typically operated independently, with little connection to wider building infrastructure. Today, that model is rapidly changing. Across modern hospitality developments, distributed […]
