Ainsworth was appointed in October and has helped the Chairboys move away from the League Two relegation places.
Saturday's 2-2 draw with Morecambe extended the club's unbeaten run to four matches and Wanderers are currently five points clear of the drop zone as the campaign nears the half-way stage.
And defender Dunne, 19, has praised Ainsworth's input in lifting the atmosphere at the club.
"He brings a different buzz to the training ground," he told the club's official website.
"You hear him before you see him! He just gets everyone going. He's a top man, there's no-one else like him.
"He's like a friend but everyone respects him. You can talk to him, but I've been able to do that since I joined. He talks to the young lads and gives us confidence."
Dunne has been used across the back-line this season due to injuries, but the youngster is happy to show off his versatility.
He added: "I don't mind where I play, as long as I'm playing and helping the team.
"It's hard to adjust sometimes but you just have to get used to it and deal with it."
