Noise makers are devices or objects that produce sound, often used for entertainment or celebration. Common examples include party horns, maracas, and clappers. They can be found at events like birthdays, parades, and sports games, where creating a lively atmosphere is desired. These devices work by using various mechanisms to generate sound. For instance, shakers create noise by moving small objects inside a container, while whistles produce sound through air passing over a small opening. Noise makers are popular for their ability to enhance festivities and engage participants in joyful activities.
