The supporters praised how safe the site was and how it also boosted the local economy.
But nearby campsite Graston Copse said people who visited for rural peace and quiet had been disturbed until the early hours by music.
Sir Mark Havelock-Allan, the closest immediate neighbour, said in his objection: “The Bride Valley is one of Dorset’s Areas of Outstanding Natural Beauty.
“In the evenings and at night it used to be so quiet you could hear an owl hoot on the far hillside.
“When the music (live or recorded) is being played at Bredy Farm what we now hear is the monotonous beat of the bass drifting across the intervening field.”
He added: “It is far from being deafening; but it is noticeable, persistent and intrusive.”
