Speaking on the show, which sees star's tell of their shameful moments, she said: "I really need to get my ears done. I'm at about ten percent and I guess the rest.
"My wife keeps saying to me, 'Stop shouting!' because I'm clearly over-projecting because I can't hear myself."
The 49-year-old is currently promoting her new book Heroic Animals: 100 Amazing Creatures Great and Small, which sees Balding pay tribute to her love of animals.
The book features 100 short factual stories about the deeds and loyalty shown by animals through time.
The former amateur jockey said: "They've made me kinder, more patient and more responsible. I think a lot of people feel the same although maybe not a lot say it. But then not many people say they love their pet more than their partner, and I think in some cases that's definitely true.
"Animals make me happy and that is infectious as it makes other people happy and it means you end up being a very warm person I hope because you're used to giving warmth from your pet and they give it back.
"It's reciprocal. There's lots of things I've learned from having animals and I'm still learning."
Heroic Animals: 100 Amazing Creatures Great and Small is out now.
