Normal Tonal Reverse Alarms Vs White Noise Reverse Alarms

What is the difference and which should you use?

As a matter of health and safety when working on a site, reverse alarms are an essential addition and a legal requirement for your machine.

However, with jobs often taking place for long hours, often through the night or situated in residential areas, you may run into a few issues with the neighbours should you have a blaring alarm go off every time you reverse your machine. 

Therefore the White Noise Reverse Alarm was born.

Initially developed to prevent disturbance of residential areas in Stratford London during the development of the Queen Elizabeth Olympic Park, in order to host the 2012 Olympic Games, workers needed a new type of reverse alarm, that would not wake sleeping residents as work carried on through the night.

White Noise Alarms also known as Broadband Alarms, emit noise over a wide range of frequencies, producing a ‘pshh-pshh’ sound as opposed to the typical tonal ‘beep-beep’. They have a number of safety and environmental advantages over tonal alarms.

  • They’re easier to identify where the precise alarm is sounding from

  • They form a more uniform sound field

  • It’s easier to identify the direction of travel

  • They are more likely to meet environmental noise regulations & limits

  • The sound blends in with background noise further away from the site so noise complaints are likely to be reduced.
