Loud alarms are devices designed to produce a strong sound to alert people to specific situations, such as emergencies or the need to wake up. Common examples include smoke detectors, car alarms, and alarm clocks. These devices use sound waves to create noise that can be heard over background sounds, ensuring that the alert is noticeable. The volume of loud alarms is typically measured in decibels (dB), with many alarms reaching levels of 85 dB or higher. This high volume is essential for effectiveness, as it helps to grab attention quickly. Loud alarms are crucial for safety, helping to prevent accidents and ensure timely responses in critical situations.
