The holiday resort on the Spanish island of Majorca has a reputation for its colourful nightlife.
Holidaying Britons flock to Magaluf every summer to party their nights away.
But local authorities are trying to overhaul the area’s image.
Music volume in bars and clubs has been limited to just 65 decibels, below the level of a vacuum cleaner or hairdryer.
Rather than trusting the local club owners to enforce the new rules, the local council has taken matters into its own hands.
Electronic devices have been implemented, which automatically mute music when it exceeds the maximum volume.
All late-night venues in the popular holiday resort are affected by the new restrictions.
Nearby Palmanova is also subject to the rules enforced by the Calvia municipality.
But some locals are not happy with the music limit, arguing that tourism will suffer as a result.
Leapy Lee from England performs in Majorca and said the new rules will “kill the place dead”.
The 77-year-old told The Telegraph: “It’s lunacy. I play in one place in Magaluf where customers are complaining because they can’t hear it.
“A lot of performers I know have lost work this season. The bars are cancelling them because they can’t use them. Live bands can’t play at all because the volume trips the limiters straight away.”
Authorities have enforced the law in a bid to transform the party destination into a family-friendly holiday stay.
There have also been new regulations introduced to clamp down on drinking in the streets and public sexual activity.
Local councillor for police and citizenship, Gori Estarellas, said the rules are “very practical and reflect the complaints that we have received basically in summer in El Arenal and the coastal area such as noise, alcohol consumption and the concentrations of people on the street”.
El Arenal is the resort which sits on the southern side of the island of Majorca.
