The Sierra de Tramuntana Association (Mancomunidad de la Sierra de Tramuntana) has acquired three mobile sound level meters, which have already begun to be used to impose fines of up to €300,000 on vehicles exceeding 90 decibels. This measure, which will be applied only in urban areas—where the local councils have jurisdiction—aims to "raise awareness" so that residents of the Serra "can feel safe in their homes," explains the president of the Association, Bernat Isern.
