Singer Leire Martínez briefly halted her performance at the Festival de les Arts due to audience complaints about insufficient volume. The event is implementing new sound restrictions following a court ruling that upheld residents' right to protection from concert noise near the City of Arts and Sciences.

Discontent over the sound level was evident from the festival's start, with chants of “No se sent, no se sent” (It can't be heard). Martínez addressed the crowd, explaining that the limitations, imposed by the city council, directly affected the artists. She was later able to resume her performance with audience support.

Complaints about the sound also surfaced at other stages. The band Pignoise apologized to attendees, emphasizing that the decision was beyond their control. Siloé, another headliner, described the situation as a "disgrace" for musicians, organizers, and the public.

This situation stems from a ruling by the administrative litigation court of València plaza number 8, which in March ordered the city council to take measures against noise from venues like the Umbracle and concerts at CACSA, to protect residents' privacy.

Consequently, some festivals, such as Big Sound, have relocated to other municipalities, like Torrent. However, the Festival de les Arts has maintained its original location, introducing a new action plan to prevent noise pollution with sound limiters and time-based restrictions.

The organization has stated that the festival will operate below current regulatory limits. The technical plan, approved by the technical section of the València City Council's Activities Licensing Service, requires a pre-opening acoustic certificate to ensure compliance with legal sound power limits.

During the day, the permitted sound level on the main stage is 85 dBA at 50 meters, while at night, these limits drop to 80 dBA at the same distance. These parameters vary slightly depending on the stage and distance.
