A spokesman added: “The speakers are used on occasion as a tactic to disperse people from an area when there is anti-social behaviour and have proved successful at doing so.
“We are reviewing the time and frequency of their use in the light of recent feedback we have received.”
Merseyside Police Liverpool City Centre Neighbourhood Inspector Jack Woodward said: “We will use all possible measures to reduce anti-social behaviour and youth-related violence because we’re determined to make our city centre safe for visitors and residents.
“In partnership with Liverpool City Council, one tactic we can use involves playing music from speakers which are located in hotspot areas. This has proven to be an effective tool in dispersing large gatherings of youths, helping to prevent anti-social behaviour and criminality taking place in the area; whilst supporting our city centre community.
“We will not tolerate such behaviour and we take every report seriously. Please get in touch if you witness or have any information about an incident and we will investigate.”
