Hello! This year I renovated an old wooden house, which is located right next to a regularly trafficked road (residential area). Meanwhile, the thermal renovation is complete, and on the wooden wall on the street side, 16 cm stone wool as well as a ventilated larch wood cladding were installed. The triple-glazed windows are new. Now only the finishing touches around the window frame are missing.
However, I have the impression that I currently hear more street noise than before the renovation, which shouldn't be the case. I have the impression that I hear the high frequencies of the street noise more clearly than is normally the case behind an insulated wall. I believe I don't hear the noises "through the window," but on the side where the window was foamed in. My carpenter tells me I have too high expectations... and I also don't want to blame him for something he can't be responsible for. So, one evening I dealt with the topic of noise and found out that the noise floor (quiet room) is around 25-30 dB and for street noise at my location about 65 dB can be assumed (according to the noise calculator of the Austrian Ministry of Climate).
From several other sources, I have learned that the performance of a contemporary triple-glazed window is about 25-30 dB. Since the bedroom window in question is relatively large (approx. 140 x 100), I supposedly shouldn't expect as much as with smaller windows, because the window apparently represents the weak point of the facade in terms of sound (photos attached).
Well then, with the help of three different apps (all on the same phone), I carried out measurements and consistently obtained approximately the following:
Noise floor: ca. 30 dB
Traffic noise outside window: ca. 65 dB (variation plus/minus 3 dB)
Traffic noise inside window: ca. 50 dB (variation plus/minus 3 dB)
The question I am now asking myself is what is "normal" under these circumstances... does anyone have an opinion, comparison values, experience...? Many thanks!
