Can someone please help me with room mode analysis?
My room is 370 cm (l), 311 cm (w), 288 cm (h)
I already look on some of this room mode calculator but I can not understand what I should do with this kind of results.
I'm in a good room? What I can do to improve my listening?
Or just explain me how to analyze the results.
Once the resonances for all the resonances are tabulated in ascending order, you want to look for resonances that are piling up around a single frequency or isolated by gaps greater than ~20 Hz. above and below it. These frequencies are where you are most likely to have tonal colorations in the sound of your room.
If you are designing a room and haven't built it yet, this tells you to adjust the dimensions to even out the distribution of resonances out. If it's an existing room that you can't move the walls in, it tells you where you are likely to have tonal colorations. These can sometimes be helped with tuned acoustical devices, like Helmholtz resonators.
The best thing you can do to assure a good sound in a room to be built is to adjust the dimensions until the distribution of resonances is as even as possible.
Nuff thanks, but sorry my ignorance I still don't understand what to do after.
I have to put how many bass trap in my room ?
I have just to start with some on the corners and go forward testing the room?
If the results tell me that I got resonance starting from 46 Hz I need lots of bass trap on my walls or as I say before, just start with some, test, and if is not right put more?

I got your PM and found your thread.
A mode calculator is meant to help find good dimensions when designing a new room. It's not intended to tell you how to treat an existing room. However, understanding room modes is useful, and this article explains the basics:
