 As someone who's worked professionally with audio and in the radio trade for many, many, many years, I find that explanation to be a bit weird. I think they were probably turning the volume up in order to hear him because he is a low talker and certainly is now at this phase of his life. And they were picking up a lot of room noise that made it sound a bit noisy. They weren't in a nice, crisp, clean, acoustically treated audio studio. They were in what looked like a closet.
