Event operators at the Badminton World Federation (BWF) World Championships used distinctive crowd-audio cues described as a “langur call” mimic around the venue. The stated action is to influence how players focus and communicate during high-pressure badminton rallies. This matters for UPSC because venue operations can shape in-competition conditions, which raises governance questions about fairness and athlete welfare.
