well when I played a 13hz sine wave I could hear this deep low rumble that was similar to the deep growl of some muscle cars. I only could hear up to 19,000k when I tested myself, I think the reason most people can't believe this is because they never have experienced that low note and may never experience it. I am autistic and I can notice a lot of things most people don't. when i switched to 12hz I heard nothing but i could feel notes down to 9hz. This is my last post on this topic so you don't have to worry about this dragging on.

I honestly cannot believe the way you guys treated him. Its his woofer, he knows how to make it pound, and its obvious he was gonna make it pound when he got the money.

How can you flame him for just being excited about his new toy and wanting to get a little creative? Do you honestly think he thought it was done correctly? fuck

For christ sakes, i've never seen anybody be all over somebody for something so small.

Kudos to STA for staying so calm and cool through all that bullshit he gave you, obviously your first post was midway through his menstrual cycle.

I can hear 17hz, and it's not just the mechanical sound of the woofer i hear.

You just can't compare the sound to anything, maybe the sound of a whale but i never heared one before.

Although i can only hear up to 17-17.5khz...

ITT - I can hear things but It doesn't really matter.

[bassahaulic 155]

I give up. Believe what y'all want.

You can't hear below 20Hz, simple as that. Science has proven it.

Can u show me a article that proves that NOT A SINGLE human can hear below 20hz?

The human ear can nominally hear sounds in the range 20 Hz to 20,000 Hz (20 kHz). This upper limit tends to decrease with age, most adults being unable to hear above 16 kHz. The ear itself does not respond to frequencies below 20 Hz, but these can be perceived via the body's sense of touch.

Show me one where a Human CAN hear lower then 20?

Thank you Duran.

The number of vibrations that are produced per second is called frequency. Frequency varies for each sound and is measured in hertz. One hertz is equal to one vibration per second. A sound with a low frequency will have a low pitch, such as a human's heartbeat. A sound with a high frequency will have a high pitch, such as a dog whistle. Humans cannot hear sounds of every frequency. The range of hearing for a healthy young person is 20 to 20,000 hertz. The hearing range of humans gets worse with age. People lose the ability to hear sounds of high frequency as they get older. The highest frequency that a normal middle-aged adult can hear is only 12-14 kilohertz. Also, the hearing range for men worsens more quickly than the hearing range for women. This means that women will have the ability to hear notes of higher pitch than men of the same age do.

the OP obviously can. Who knows what he can and cannot hear just becuase someone did a study on it. Maybe he's superman and we just don't know it. You never know, and it's just wrong to make assumptions all the time about things because you don't have things in front of you to judge for yourself.

Correct.

There has never been a study that says it isn't possible.

Well he claimed 13Hz and that is impossible.

You can not test how low you can hear by yourself with a subwoofer. There are far too many variables which are going to invalidate any results.

For starters, when you play a 13hz tone, your subwoofer isn't only playing a 13hz tone. It's also going to be reproducing tones at 26hz, 39hz, etc, which are known as harmonic distortion, and are within the audible spectrum of sound. Many people hear the 2nd and 3rd order harmonic distortions being produced (which for a subwoofer producing a 13hz tone at any reasonable output level, the harmonic distortion level is going to be extremely high) and mistakenly think they are hearing the fundamental, when they are not. So just because you "heard" sound when you played a 13hz tone, it doesn't mean you actually heard 13hz. You may have been hearing 26hz, 39hz, etc, and mistakenly thought you heard the fundamental 13hz tone.

Then you also have issues with mechanic noises being generated from the driver, resonances from items within the room, etc, all of which are going to completely invalidate your test results.

So the short story is no, you've done absolutely nothing to demonstrate you can hear down to 13hz.
