Following complaints by viewers, the BBC is to re-edit its flagship science programme Wonders of the Universe, toning down the background music.
Hundreds complained that the music drowned out the commentary by astronomer dish, Prof Brian Cox.
Jonathan Rentouf, the show's executive producer, admitted there had been an error of judgement and added: "We are remixing the sound for all the films to pull down the music and effects levels during the segments where Brian is talking and we are very hopeful that will correct any problems."
TV vigilante, TV Repair Man, welcomed this result of viewer power.
He told EIF News & Features: "This is a remarkable success for the viewers.
"Inprimis, to get a BBC 'Tristram' to admit to an error in production values is to be celebrated. And, secondly, for that admission to lead to a volte-face, is unheard of.
"While TV Repair Man's agenda does not, at this stage, include music and sound levels in documentaries, he applauds this triumph.
"But the struggle to banish moronic reality shows and constant repetition, recapitulation and inane voiceovers in daytime TV continues.
"While these evils persist, no-one who has any part in visiting them on the viewing public is safe from TV Repair Man's vengeance!"
