Error (due to coordinates?) in version 4.0.4 about noisemodelling HOT 2 CLOSED

Hi,

Not related to the issue but you should place the receiver using height > 0m .

Did you try to set a Z coordinate to roads ? It is the height (relative to the specified digital elevation model) of the road. I think to noise emission will add 0.05m to the height as the position of the sound source.

Thank you @nicolas-f .

Setting Z value for receivers does not always solve the problem, but by setting Z values for roads, the error no longer appears, while I don't confirm that no errors appear in any settings. It would be nice to find out if the real cause of the error is in the road coordinate settings or if there are still other causes.
