Loud, or noisy, refers to sounds that are high in volume and can be easily heard. This can include sounds from various sources, such as traffic, music, or construction work. Loud noises can be disruptive and may cause discomfort or stress for people nearby. In many environments, excessive noise can lead to problems like difficulty concentrating or sleeping. Some places, like concerts or sports events, are designed to be loud and energetic, while others, like libraries or hospitals, require a quieter atmosphere. Managing noise levels is important for maintaining comfort and well-being.
