One data point, personally observed. We were expecting our first and was probably about 7 or 8 months along - not quite as far along as the woman pictured. I had been doing some work on my wife's car and she came out to check on me/whatever. She was standing in front of the car beside me as I dropped the hood closed, which made the expected thunk noise. She jumped back - as soon as I had dropped that hood, the baby kicked her from being startled. So yes, I'm sure that baby at the track was hearing that noise!
