Jeg har mikrofon og lurer på om det finnes noe program man kan bruke til å undersøke db nivået. Nivå matching er jo viktig nå man prøve ulike ting og tang.
http://www.hometheatershack.com/roomeq/wizardhelp/help_en-GB/html/measurementlevel.html#topSetting the signal level REW uses during measurement involves generating a pink noise calibration signal and adjusting the AV processor's volume control and/or the calibration signal level so that at the measurement point (usually ear height at your main listening position) your SPL meter shows a level of around 75dB. The soundcard's input volume then needs to be adjusted to get a good signal level from the SPL meter or mic preamp when the cal signal is playing.
http://www.gearslutz.com/board/studio-building-acoustics/359008-using-room-eq-wizard.htmlyou don't need an spl meter - just set your monitors to a comfortable listening level and tell the program that's 75db when you run the calibration test. of course, it'll be wrong, but the frequency response is just as valid relative to itself.
