If you are planning to travel to Murcia, get used to wearing sleeping with silicone earplugs beforehand. Murcia has a major problem with noise pollution (deafening motorbikes, dogs barking on balconies all night, drunken teenagers in huge groups on street corners, crowds of people literally shouting each other down in restaurants). The residents are used to it due to hearing loss. Take my advice; I've lived here for eight years.
