In Reply to: Re: If you have a frequency sweep just sit down and listen to it (when in doubt use your ears) posted by AVsponge on May 19, 2004 at 11:48:49:
+ the wife bellowing T*U*R*N ...... I*T ...... D*O*W*N,
the dog howling ... and Police sirens approaching after your neighbor called them about your excessive noise.You can't plot a bass frequency response with a sinewave sweep -- it's just a tool for listening ... and estimating total bass SPL deviations (+/-xdB) when you use a sound meter with fast response.
I can get pretty close to locating the center frequencies of bass peaks using 1/6 octave spaced sinewave tones from my Stryke BassZone test CD. 1/12 octave is even better. Every Hz. for nerds who must have "perfection".
I double check results with the ultra slow 5 minute sweep from
1 to 100Hz. on that disc.My corrections are usually done with several 1/6 octave bands, sometimes 1/10 octave -- rarely 1/4 octave -- and never 1/3 octave (so far)
