Sonic 'Anti-Homeless' Device Sparks Outrage in Perth
18 Feb
Summary
- A loud, piercing noise device was installed to deter homeless people.
- The device was installed under the Lord Street Bridge in East Perth.
- The device has since been turned off following public outcry.

A device designed to emit loud, piercing sounds to discourage homeless people from camping under Perth's Lord Street Bridge underpass has sparked significant public backlash. Installed by the City of Perth, the technology produced a shrill, buzzing noise intended to be uncomfortable for human ears, described by a local activist as 'hostile architecture.'
The device, managed by the Public Transport Authority (PTA), was reportedly turned off by Tuesday morning following widespread criticism. Social media users expressed outrage, questioning the council's approach and highlighting potential harm to animals. A person experiencing homelessness noted the noise's intensity in underpasses across Perth.
The PTA stated they have deactivated the device and are asking the City of Perth to determine a better course of action. The council defended the measure as part of a safety approach addressing antisocial behavior and community concerns, alongside increased security and CCTV.
This incident is reminiscent of a 2023 case where the City of Bunbury played The Wiggles' music on loop to deter homeless individuals, a move later halted after the band intervened.
