Founded by Zanna (Rozana Bruno Lopes), a Brazilian singer, music producer, and sound engineer, in Rio de Janeiro, around 2007–2008, the company is considered one of the pioneers in Brazil in sound branding, which is the strategic use of sound to build a brand's identity.<ref name=":0" /><ref name=":1" />

Zanna Sound is Latin America's first sound branding agency.<ref name=":1" />

== History == The origins of Zanna Sound are closely linked to its founder's early initiatives in sound design. Around 2009, Zanna began developing ideas to improve the auditory experience in public transport systems after encountering the use of generic background music, including works by Antonio Vivaldi, in stations of the Rio de Janeiro Metro. She proposed an alternative approach focused on creating a localized and functional sound identity.<ref name=":0" />

Zanna personally approached metro authorities with her concept, advocating for a more cohesive auditory environment. In 2011, she became the voice behind the Rio de Janeiro Metro's automated announcements, marking the beginning of the company's involvement in large-scale transport projects.<ref name=":0" /><ref name=":3">{{Cite web |date=2025-08-24 |title=Música MetrôRio ganha letra após 14 anos!

==Zanna Sound’s notable work== The company gained prominence through its work with the Rio de Janeiro Metro, where it developed a comprehensive sound identity system, including automated announcements, passenger guidance messages, and overall auditory experience design.<ref name=":0" /><ref name=":3" /><ref name=":4" />

This project is considered one of the company's earliest and most significant case studies, frequently cited as an example of the application of sound branding in public infrastructure.<ref name=":0" />
