Rangers fans were urged to raise the roof and the noise level at Ibrox - and they certainly answered the call with a raucous crowd roaring Giovanni van Bronckhorst's men on to an historic result.
It's no secret that the Light Blues crowd can act like a 12th man on big European nights and that was never more evident than on Tuesday when the supporters helped the team overturn a two-goal first leg deficit for the first time in their history against continental opponents as they defeated Union Saint-Gilloise 3-0.
But just how loud is the noise when the famed atmosphere is crackling? Well, against the bruised Belgians it touched 100 decibels on at least five occasions – report the The Scottish Daily Express – on what was an electric night. That is getting close to chainsaw level. A reporter was at Ibrox with a sound level meter and it was off the chart, with the journalist blown away by the noise.
