Buzzer and sporting events

A buzzer is a sounding device that can emit a short sound. Although it may seem unconspicuous, it may sound somewhat unpopular, but in everyday life it uses a "weak" voice to prove its existence. It has its presence in almost any place where electronic products need to be heard. In the microwave it stands for "OK, I got the food done", in the elevator "Get Out, I'm overloaded", in the printer it's "I started working", in the subway it's "Attention, I want closed"……

In addition to daily life, sports events are also a great place for them to show their talents. With the continuous development of sporting events, the rules and penalties have become more and more stringent, and buzzer has also appeared with many electronic partners.

In volleyball, according to the provisions of the International Volleyball Federation, during the volleyball match, the coach should press the buzzer before changing or pausing, and then can make a change or substitution or pause gesture. In addition, the buzzer will be sounded when there are two technical pauses in each round.

In basketball, a buzzer is placed on the rostrum, and the recorder operates in some cases to issue a sound similar to the air whistle to prompt the players and the referee. For example: 24 seconds, end of pause, end of section, and violation.

However, it is clear that the buzzer will occasionally make a difference, like a person, to make a big oolong.

In the third game of the 2010 World Women's Volleyball Championship, the Chinese team made a good start. There was a problem with the buzzer on the court with a 3-0 lead. The Chinese players thought that the Canadian team called for a timeout. All the players went on the court and the result was judged. Serve a penalty of 8 seconds. The referee also used the buzzer. No change was made.

In the 2010 Warriors against the Nuggets, Monta Ellis scored 32 points, including a turnaround jumper that was ten feet away in the 15.2 seconds before the final to help the Warriors lead the game for the last time, but he was in the 0.4 seconds before the game ended. R. Smith's foul gave the opponent three free throw attempts. Eventually, the Warriors defeated the Nuggets 122-123 away. The focus of the debate is whether the foul was before or after the buzzer at the end of the game. Warriors coach Nelson Nielsen is obviously not calm enough: "You lost to the buzzer. It's very difficult."

Of course, this happened because they did not appear in the finals. In view of the reaction time after hearing the voices, the referees often went back to the video to decide the penalty in a very important game. Do you think that less than one second is not important enough? Then you must not know the wonderful 0.N seconds in basketball history.

However, FIFA President Blatter said that misjudgment is part of football's charm. Then we have reason to believe that these misjudgments caused by buzzer are also part of the charm of sports events.
