History of International Sound Check Day
International Sound Check Day has an unusual, fascinating origin rooted in the world of professional audio. Although the tradition of sound checking existed since the earliest days of amplified performances in the 20th century, the idea of dedicating a special day to honour the practice emerged much later.
The unofficial beginning of International Sound Check Day can be traced back to 2015, when a collective of global audio engineers, sound technicians, and event professionals began acknowledging January 2 (1/2) as a playful nod to the universally used microphone check phrase “1, 2… 1, 2.” The idea was initiated by members of several professional audio communities on social media—particularly groups like SoundGirls, AV Educate, and independent touring engineers—who consistently highlighted the importance of sound checks across the world.
By 2017, the tradition gained widespread acceptance within the global audio community, soon embraced by concert organizers, touring crews, recording studios, broadcasters, and performing arts institutions. The idea was not founded by a single individual but became a collaborative movement—an organic, collective expression of gratitude toward sound engineers.
Today, International Sound Check Day is recognized across continents, symbolizing both technical excellence and creative harmony.
