or is there no point? what about for 'feel' rather than hearing the note, would it work on a club system?

There is no point. Not many PA systems put out enough Db at that range. Another point would be that you can't hear under 60 Hz that well, so -20 Hz would just be air hitting you rather than a rumble, also their would be a problem (I imagine) with rendering sound that low on software/hardware aswell as playing it back.

I made a 9hz sine sub note in hopes to see some ravers shit themselves, but alas the brown tone was indeed a myth.

But in all seriousness most humans can't hear anything below 20hz. I listened to 20hz in a professional studio and I perceived it more as a feeling than a sound, 23 hz was definitely audible though. Everyones ears are different.

As for not hearing anything under 60hz that is a bit of an untrue statement since on most PA rigs at decent venues you will hear and feel right down to 40 hz. I don't think many PA's are equipped to throw anything below 20hz or even close to that. Maybe funktion one rigs or valve or something but who knows.

As for production its pointless to really go that low and in fact I low pass everything at 35 hz just to clear up rogue frequencies down there. If you use a spectral analyzer on others tracks you will see that this is quite common.

Hope that helps a bit.

It is a myth kinda. It could turn your insides to jelly if played loud enough. PA systems, some may hit that note but not nearly enough db to do any damage.

If you put a tone that low in your tune, all it will do is eat up headroom on your mix.

Much of bass is feeling anyway. Try going up the frequencies with your monitors on very very low volume. You probably won't hear anything until you start going into the mid-range.

But yeah, even 20hz is a bit too low for most systems. I find the sweet spot for powerful sub bass is around 50hz.

That's the long and the short of it really It doesn't stop some people trying though Generally 30-40 is the 'accepted' cutoff point, but some people still try to stick trouser flappers in

Something very much worth mentioning is that it is down to note selection above anything else. Especially for clean digitally/VST-generated bass sounds, so long as the fundamental is in the right place (ie above 30 or whatever) then a HP filter is unnecessary. Naturally, pitch drop basses need taking care of, but I wouldn't slap a HP filter (especially a sharp one) on something if it doesn't need it. Everything has a cost

Just thought I'd mention it

Low pass at 35hz?

I've ran into some people who say they low pass at 40 hz even. Although they might be using a 36 db slope rather than a harsh 48 or something. Who knows. But basically all you are achieving at frequencies lower than 30 - 40 is the ability on a rare system to shake some trousers (as macc was saying).
But at the cost off eating up valuable headroom in your mix, I would rather just low pass.

I was informed about the 'Pink note' the other day

Money!!

reminds me of someone on doa saying he heard some different bass he never noticed in breakages so vain when it was played on the valve soundsystem.

pink note?

do explain

I assume that by low pass you actually mean high pass.. low pass would mean that you only allow the frequencies below 40Hz to go through, which would mean that the track would be nothing but inaudible subfrequencies...

8hz can kill you if its played loud enough

apparently people have died from using machinery in factory's for years which oscillates at ultra-low frequency's. autopsy's have shown internal organs turned upside down.

Death by Dub.

loads of people where seeing things that they took for ghosts in a big warehouse. they called in ghost investigators and they discovered that an air cooling device was omitting a very low frequency that effects how we see, they switched it off and ghosts where gone.

i put the frequency in some of my tracks along with other body effecting frequencys.

Not really sound though is it

I doubt you heard 23 Hz definitely... 30 Hz is just about audible, 20 is the very very low stretch of what ur brain will pick up but yeh, u probably won't notice it... you probably heard spill over frequencies due to inevitable distortion in the system. I assume
