Key Differences
An alarm can be any device or system designed to alert or warn of danger, including a range of sounds and notifications, whereas a klaxon specifically produces a distinctive, loud, and harsh sound, often recognized as an "ahooga" noise.
Alarms are used in various settings such as homes, cars, and workplaces for different purposes including fire, burglary, or emergency notifications, while klaxons are typically used in situations requiring immediate attention, like in submarines, industrial sites, or older vehicles.
The function of an alarm can vary from simple noise-making to complex systems that integrate with other security measures, whereas a klaxon has a more singular purpose focused on creating a loud noise to rapidly draw attention.
Alarms can include visual or textual notifications and may not always be auditory, whereas klaxons are exclusively auditory and are noted for their distinctiveness in cutting through ambient noise.
The use of alarms can be customized for sensitivity and response, including silent alarms that notify only specific services, while klaxons are straightforward, designed only to alert as loudly and urgently as possible.
