Qualitatively speaking it definitely is a problem in Germany. DB planning rules used to include a guidance note that noise barriers higher than the typical lower edge of a train window should only be considered in exceptional cases. Two or three decades of constant complaints about train noise have led to legal rules and planning regulations having been significantly tightened up and now mean that four, five or even six metre high noise barriers are nothing out of the ordinary for new-built infrastructure.
The result being that people still complain about fear of more noise when new infrastructure is proposed (despite freight trains having gotten quieter, too, due to the introduction of new brake shoes), but now they're also complaining about the visual blight, too. (And nobody cares about the views of the train passengers.)
Meanwhile in Switzerland for example the current state is that balancing noise reduction needs vs. the visual impact of noise barriers still is an official planning goal because apparently people haven't been screaming so loudly about noise and nothing else, so the Swiss tend to build fewer and lower noise barriers even today.
(Also purely empirically from my visits there, the UK also doesn't seem to build as many and as high noise barriers, even on infrastructure that has been newly built or rebuilt within the last two decades.)
