I've noticed that the noise from larger tyres fitted to SUV's and EV's etc. are an increasing source of noise on the motorways. I'm looking at simple motorcycle ear defenders, which cut out the background wind and road noise whilst allowing conversations, radio etc to be heard. It's not an ideal situation but I'm finding the motorway background noise is growing and becoming more intrusive now, and from my motorcycling days ear defenders do exactly that.
The Morgan CX is a very capable car to travel vast distances at high speeds, which then exposes you to far more background noise. I've not experienced quite the same problem with the roof up as you seem to be experiencing, but certainly its quieter upto a certain point with the roof down, but I've always found that to be the case with even triple lined roofs.Lining a roof shouldn't present too much of a problem for a trimmer, the ARP Morgan had a lined roof...but bear in mind you still have a simple plastic rear window. I've found putting more sound deadening material in the cabin especially foot wells, engine bays and rear parcel shelves all helps.
I've always had soft top cars and always drive roof down, so I'm used to it over the years........but still looking to get ear defenders, as the noise levels of other cars has changed especially tyres for the worst...
