During an interview with Chris Van Vliet, WWE Producer Tyson Kidd talked about what led to the company piping in crowd noise at the Thunderdome:
“The first day at Amway was not [piped in]. Bayley was like, ‘TJ, it’s so awkward.’ We had gotten used to the NXT audience, so it was a little something. In the meeting, they were like, ‘What did everyone think?’ I said, ‘The ThunderDome looks awesome. Is there any way to pipe the noise into the arena because it will help the talent. I spoke with a lot of talent from the week before and they said that was what was missing.’ Kevin [Dunn] said ‘no problem.’ So, they pump it in and it helps a lot. It at least helps you lose yourself a bit and letting go I like to think I have my pulse on the talent and I ask them questions. Bayley was the one who told me. Then I asked the locker room and they all said the same.”
