Draft bye-laws to regulate busking in Dublin city centre will go before a full meeting of councillors next month.
The proposals will see buskers having to pay an annual fee of €30 for a permit and €60 if they are using an amplifier.
Councillors from the Arts and Culture committee discussed the plans at a meeting this morning.
Fianna Fáil's Jim O'Callaghan queried the bye-law on noise.
"It's slightly vague in bye-law number 10 - it doesn't set out the actual extent of the amplification that's permitted," he said.
"It's a general requirement that the noise can't be so loud, so continuous, so repeated as to give reasonable cause for annoyance.
"I wouldn't like to be interpreting that."
