I am fairly new to acoustics. I understand how sound propagates but I don’t quite get how I should treat my room issue.
I get an ugly boost at around 150Hz, which kills any song including a heavy D3 note. I have started to put on bass traps on the back of my sound system, but the problem remains.
The room size is 260cm * 350cm, ceiling height 230cm. I should mention the ceiling is not totally flat. It’s curved on the left about 30% of the ceiling surface. Also, the ceiling surface is wood.
I have a sliding door on my left that is covered by curtains. A window on my back also covered by curtains. And sliding panels (my room is japanese tatami style room) on my right that are not covered.
I am not sure what to do next. Keep covering corners with bass traps? Or is this 150hz boost potentially caused by anything else? I read on another thread ceiling height could be the problem.
Thanks for all the advises left on this forum anyway!

P, A 150 boost comes from a 37 Hz. issue with your room. Fill out the data in this link so we can take a look at your entire room. The corners of your room are not your problem. Your issue is one of the dimensions and unwanted pressure. https://www.acousticfields.com…..-analysis/
