The Speaker interrupted exchanges between David Cameron and Ed Miliband to warn a barrister-turned-MP to "Learn it man".
John Bercow told Northampton North MP Michael Ellis he considered him to be a "distinguished practising barrister" but warned the Conservative MP's noise was not acceptable in a court room, or in the House of Commons.
He later told MPs that the public had a "low opinion" of the noise in the chamber during PMQs.
