Is the official correct to assess a technical foul to the home team for fans using artificial noisemakers?

The official would be correct to assess a technical foul to the home team for fans using artificial noisemakers, as it is against the regulations. The rules governing basketball are designed to ensure fair play and maintain order during the game, including how spectators might influence the environment.

While fans might not be directly penalized themselves, the responsibility for maintaining a compliant game atmosphere falls to the home team. If fans are causing disruptions with artificial noisemakers, the official can assess a technical foul against the home team since it's understood that a team's environment, including fan behavior, can affect the game. This maintains a level of accountability for the home team regarding their supporters. Moreover, the use of artificial noisemakers can be considered a violation of conduct expected during play, which justifies the foul.
