The dome is deffinetly going to be darker (less natural light). The PTFE is about as translucent as the old roof, but the old roof was the whole dome, this is only about 50% of the roof covering. The new LED lights will be very bright and may make the dome look as bright, if not brighter. But there will deffinetly be less natural light.
I know I’m beating a dead horse about the noise. But if they are indeed added insulation under the non-PTFE I just can’t imagine how the dome will be even close to as loud. Insulation kills noise. I was hoping that would be metal underneath the non-ptfe section to reverberate the sound. I personally don’t care about the acoustics in the dome for concerts and such, I care about a home field advantage and I’m worried we are losing that.
