Logo for a building physicist

Hello there,
I am currently working on a logo for a building physicist with a focus on thermal insulation, noise protection and acoustics.

Each of the surfaces stands for one of the focal points. I did not find it easy to represent noise and acoustics in terms of colour, which is why I chose red (warm) and a gradation of blue (cool, technical).

What do you think?

I look forward to your criticism and feedback.
