SV Werder Bremen is a professional football club based in Bremen, Germany, and its Nebelhorn is the foghorn sound associated with home matches at the Weserstadion. The horn is sounded to mark goals and big moments, giving supporters an unmistakable audio cue that is closely tied to the club's identity. Clips of the sound have circulated online as ringtones and soundboard files, where fans reuse it outside the stadium for edits, celebrations and matchday posts, keeping it recognisable even to people who have never attended a game in Bremen.
