Hi Guys,
I am a frequent reader of the Forum but just created an account because I ran into problem treating my listening room.
Problem: There is a specific frequency within the female voice range which is extremely position dependent. In my listenting spot the 'n' letters in a song are so extremely boomy that my eardrum hurt at even moderate SPL.
When I leave the "sweet spot" it is fine. My frequency SPL curve has 10dB variations in the mid range frequency so I suppose this is a very particular case and problem related to one frequency in that song.
My questions are as follows:
1. How can I figure out the exact frequency of that part of the song so that I can better adress it. Room EQ Wizard doesn't seem to record frequency over time, just SPL. Is there a good software for this? I do have the standard UMIK-1 from MiniDSP.
2. I doubt that this is only a raise in dB as it really sounds boomy. However I don't have any high reverb above 80Hz. Can boominess be caused by combfilters/SBIE as well?
Some information about my system:
- I have the Linkwitz LXmini. It's basically a point source from 70Hz onwards. Radiation pattern is monopol from 70Hz to roughly 700hz where it transitions into a pure dipol. Around the transition region of 700Hz the backward part of the diplo cancels out the backward portion of the monopol thus creating a cardioid radiation pattern. Below 70Hz there are two dipol subwoofers which are pointing towards the listenting spot but are not toed in.
Due to the diplol character I have no problems with sidewall or frontwall (behind speaker) reflections. All early reflections <40ms are caused by the backwall (will be treated soon) floor and ceiling.
Room is 4.55m x 4.65m x 2.5m and I do have the respective modes wrecking havoc on my low end at 40Hz and 70Hz. However I doubt that this is related to the boominess in that female singing voice range...
I really need help in finding those problematic frequencies.
In my sweetspot the Low end response is fine so I can't really move around much. At the spots where that singing voice boominess is gone the lowend booms like mad.
Best regards
Martin
