Yes turtles do make noise when they mate with each other.
When a turtle or turtles mate the turtles make a noise which is a peculiar barking sound.
If you hear a sorta peculiar or weird barking sound similar to a dog barking but you know it's not a dog barking then it's likely turtles mating.
Turtles mate at all hours of the day and night.
I used to hear a weird barking noise when I lived on a farm with my family as a kid.
I believe I was around 7 years old at the time and in my bedroom and I heard a weird barking noise and looked around for a dog or dogs and I saw nothing.
I was scared so I went to my parents and my dad said it was turtles making the barking noise when they were mating.
He was right and showed me 2 turtles mating outside near my bedroom window.
So yes turtles do make noise when they mate and it's a weird noise.
