After 10 years playing in front of 3000 fans as Cheltenham Town's keeper, Brown has taken the leap to the Scottish Premiership in his stride.
Brown moved to Aberdeen this summer and has broken into the first team ahead of Jamie Langfield, making six appearances in all competitions so far - and keeping five clean sheets.
But he admits to being in awe of the Dons' attendances after being used to playing in front of the Whaddon Road faithful.
He told the Gloucestershire Echo: "It took me longer to get settled and get up to speed than I thought but I am now a lot more confident.
"I don't think people realise how massive this club is down south. But we play in front of 19-20,000 fans.
"We sell out 3,000 away tickets easily. It is a fantastic place to play football, with games on TV and in front of the big crowds.
"I was nervous for my debut but I have learned to take it in my stride. The older you get, the more you get used to it and look forward to it."
