In Hanoi, Vietnam, pickleball has become very popular, but it is causing noise problems. The game, which is played with paddles and a plastic ball, makes a loud "pop-pop" sound. This noise starts early in the morning and continues late into the night. Many people are upset because they cannot sleep or concentrate.

Hoa Nguyen, who lives near a pickleball court, said, "The noise makes it impossible for me to sleep." She has complained to local authorities.

The sport has grown quickly in Vietnam, with many new courts built in crowded city areas. However, the noise is causing stress and health issues. Some people have even moved away because of it. The government is under pressure to find a solution to this "acoustic hazard."
