How should a referee respond if the automated horn buzzes during a rally?

When the automated horn buzzes during a rally, the appropriate response is to replay the rally if the affected teams were influenced by the interruption. This protocol is designed to ensure fair play, as the unexpected noise from the horn can distract players or disrupt their concentration, potentially affecting the outcome of the rally. By allowing a replay, the integrity of the game is maintained, providing both teams an equal opportunity to compete without the undue influence of the external sound.

In contrast, stopping play immediately would halt the game unnecessarily and could disadvantage one of the teams if they were not affected. Allowing play to continue disregards the potential impact of the horn on the players and the flow of the game. Stating that the result of the rally stands ignores the disruption caused by the automated horn, which contradicts the objective of maintaining a fair and competitive environment. Hence, the decision to replay the rally is the most appropriate course of action.
