Venice will ban loudspeakers and tour groups of more than 25 people to reduce the impact of mass tourism on the Italian city.
The new rules will take effect from June 2024, the city said in a statement.
The use of loudspeakers is prohibited because they can "cause confusion and anxiety," the statement added.
Over-tourism is widely recognized as an urgent problem for the canal city, which is one of the most visited places in Europe.
In September, Venice approved the trial introduction of a €5 fee for day visitors.
Elisabetta Pesce, the city's security official, said the latest policies were "aimed at improving the management of groups organized in the historic centre".
The city has an area of only 7.6 square km, but in 2019 it welcomed almost 13 million tourists, according to data from the Italian National Statistical Institute. Visitor numbers are expected to exceed pre-pandemic levels in the coming years.
Earlier this year, UNESCO said the city should be added to the list of endangered world heritage sites as the effects of climate change and mass tourism threaten to cause irreversible changes to it.
In 2021, large cruise ships were banned from entering Venice's historic center via the Giudecca Canal after a ship wrecked in the port. Critics argued that the ships caused pollution and undermined the foundations of the city, which suffers from regular flooding./BGNES
