"Loud" refers to sounds that are high in volume, making them easily heard. This can include noises from various sources, such as music, traffic, or construction. Loud sounds can be measured in decibels (dB), with higher numbers indicating greater intensity. Noisy environments can affect people's comfort and concentration. For example, a busy restaurant or a crowded street can create a loud atmosphere that may be overwhelming. Prolonged exposure to loud sounds can also lead to hearing damage, making it important to manage noise levels in different settings.
