NEW low-frequency sirens that can be "felt" will be installed in 25 fire trucks in Sydney, Newcastle and Wollongong, to alert headphone-wearing pedestrians and drivers to get out of the way.

THE state government announced the rollout of the "rumbler" subwoofer sirens, which will be installed on the front of the fire truck to creates vibrations that can be felt from a range of up to 60 metres.
