Over 160 street performers have got licences to perform since Dublin City Council brought in the bye laws on 7 April.
The council have received around 50 complaints from residents and businesses for breaches of the regulations.
They issued two warnings to one performer who refused to comply and that licence was revoked.
Buskers have formed their own representative group Dublin Street Performers (DSP) and say the new regulations have stopped over crowding as performers have to be 50 metres from each other.
They say the limit of two hours on each performance stops people "hogging spots".
But as part of the review next September they want a recognised queuing system and later night time limits, currently they have to stop at 11pm.
Residents of Temple Bar where there is a special limit of 75 decibels say the situation has improved with less amplifiers being used and more acoustic musicians.
The limit in the rest of the city is 80 decibels and businesses also say there has been an improvement.
Some retail outlets at the bottom of Grafton Street's pedestrianised area still have issues and the council is carrying out acoustic tests to see if the street layout is causing particular problems.
The laws require buskers to pay €30 for a permit with an additional €90 to use an amplifier.
They are not be allowed to play outside the GPO or in Temple Bar on the street between Temple Bar Square and Eustace St.
The laws also bar buskers from performing within 3 metres of any private residence.
Street performers using knives or flame have to have public liability insurance of €6.4 million.
Fines of up to €1,500 can be imposed for breach of the regulations.
