WHAT ARE THE OPTIONS?
First, you can choose between a tonal alarm and a multi-frequency alarm. Industry experts have suggested either can provide an effective warning and each has its merits. Second, you must choose an alarm with the appropriate sound pressure level (SPL).
If you know the ambient noise level and it remains reasonably constant then the appropriate fixed dB alarm can be selected, whether tonal or multi-frequency.
Fortunately, ECCO pioneered another solution — the Smart Alarm®, available in either tonal or multifrequency. Smart Alarms monitor ambient noise automatically and adjust their output to 5dB above that, satisfying OSHA’s requirements. Perfect for worksites with inconsistent noise or varying noise levels.
TONAL VS. MULTI-FREQUENCY
Tonal alarms emit sound at a single predominant frequency resulting in the familiar ‘beep-beep’ warning signal that we’ve all grown accustomed to. Conversely, multi-frequency alarms emit sound at multiple frequencies within a narrow band resulting in a ‘shhh-shhh’ warning sound. There is no scientific evidence to prove either sound is more effective than the other in a reversing vehicle application. However, there are several points of view that should be considered when choosing between the two.
SMART ALARMS
Listen. Adjust. React. Smart Alarms self-adjust to varying environmental noise by continually listening and reacting to ambient sound levels adjusting their output to 5 dB(A) above to ensure their sound is audible without creating a nuisance. It’s the smartest way to ensure OSHA compliance and eliminate noise complaints. Choose from tonal and multi-frequency models.
MULTI-FREQUENCY
Commercial vehicle noise pollution is a growing problem, especially in residential areas and densely populated or confined locations. ECCO’s multi-frequency alarms use a range of sound frequencies within a narrow band to emit a warning signal that is perceived to be more directional and to dissipate quicker than a tonal alarm. Keep the peace while complying with OSHA safety standards.
