Differences in frequency

[mjoekingz28]

Is a difference in frequency as prominent the higher you go?

Eg, the obvious difference of going from 40Hz to 41Hz.....is it as noticable as going from 4000Hz to 4001Hz?

I would try to find out myself but my test tracks do not really allow for such minute measurements at the higher frequencies.

What are you using test tracks for and what type of test tracks are you referring to?

No

At those higher frequencies it is much harder to hear

If you think does 20hz sound different than 40?

Completely

How about 10,020 to 10,040

That you will not be able to hear the difference

With a good ear and good system you can easily hear a difference between a 40hz note to a 41hz note.

You may be able to, not everyone can.

Yes, 40 and 41 may be distinguishable...but is 10,000 and 10,001? That is my question and has been answered.

The test tracks I refer to are sweeps and tracks where the time equals the frequency....eg 40 seconds into the song equals 40Hz. I think that is the programming I was listening to.

I have a disc that I can hear about any audible frequency below 100Hz (20Hz-100Hz) in one hertz increments. I do not have such programming for 100Hz's, 1000Hz's, or 10,000Hz's that I could use to listen and see what each frequency sounds like. Like some cops might do when on the side of the road guessing how fast some cars are going; then looking at the radar gun!

It's relative to each individual's ears believe it or not. I'm much more sensitive to lower frequency sounds and can notice the difference between lower 1hz step increases and especially octaves compared to higher frequency steps and octaves. It's obvious the human ear can hear higher notes better, but those higher notes don't travel as far as lower notes when a home audio system is properly tuned. I've been drinking so take my writing as opinion-only.

Bass track CD containing all the freq is easy to hear at a moderate level and it's a tone used. I think it runs for about 5 sec. each. I had one and have no idea where it went. But it had 20Hz all the way up to 60Hz.

The upper freq is a diff story. Some are harder to hear than others.

Good point fixinit! From 20Hz to 40Hz in one octave while 5000Hz to 10000Hz is one octave. Both double in frequency, but the lows only go up by twenty hertz and the highs go up by 5000Hz in this example.

I was reading on a manufacturer's webpage and they said something about a bunch of math being involved and we hear logarithmically not linearly.

Most people if not all can hear the difference from 40 to 41

I don't think anyone in the world can hear the difference from 10,040 to 10,041

That is a change of .01%

Also if it's listened to loud there is even less chance to hear a difference

Above 150db the human ear starts to loose sensitivity and has more trouble hearing changes

Even distortion becomes harder to hear above 150db

Oh heavens YES there is math involved! I'm an Electrical Engineer by degree, THE most math intensive engineering degree there is I think. For example all other things being equal, a signal to be "twice" as loud it must be TEN decibels louder, not twice! And the reason clipping and the basic "square wave" is so damaging is because a square wave is analytically made up of a combination of many higher frequencies than the fundamental frequency being produced. In Fourier analysis, the mathematical representation of a square wave is an infinite series of additive and diminishing intensity higher frequencies than only the fundamental frequency.

I posted a pic I'd scanned of my EE degree diploma, and BoominTahoe I think called it a fake! Screw that, if you denizens of Caraudio.com can't accept objecive EVIDENCE, then there is NO hope for you! I'm tired if trying to show you the way to The Truth! :-( No one so stupid as those who WILL NOT LEARN!
