Which of these describes one way that the human nervous system maintains a constant body temperature when the external temperature is cold?

We had a discussion recently with a client about our role at open-air concerts and how and our role when it comes to monitoring concert noise. We told her how it was our job to ensure that noise levels from the concert are kept to within a designated noise limit at the nearest noise sensitive property by means monitoring the noise levels and consulting with the touring sound engineer during the show. She jokingly said the following in response:

“ Well, obviously you weren’t doing your job properly! I live near Terenure and I could clearly hear Ed Sheeran playing in Phoenix Park last year. That’s miles away, on the north-side! The music would have needed to be blasting out of the speakers in order to reach my back garden, are people deaf? How come I can hear the sound from a concert when I’m on the other side of the city?”
