Tonedeafness + Pitch Perception

[Armin]

How tonedeaf are you? 80.6%
How perceptive of pitches are you? 0.6

[Sidoh]

75%, 0.9.  No musical training.

I'm pretty sure I have a hearing problem too, but I don't suppose that affects this sort of a test when you're wearing headphones.

Neat test, by the way.

[Ergot]

Umm... 75% 12.3!? The second test is terrible... I took it once and it said it failed or was out of range or something, took it again got 12.3 :|

[AntiVirus]

Rofl.. I did terrible on the first one.  But I think it was because my room mate and his friend were being really loud.  Either way, I got 69.4% on the first one, and then an error on the second one.  The same Error Ergot had.

[iago]

55.6%
8.1

This is just further proof of something I already know -- I am absolutely tonedeaf and have no musical talent whatsoever

[Joe]

44.4%. Good game, iago, but I lose!

You would be a great country singer...

[Chavo]

I haven't taken the test yet, but I imagine this test is pretty flawed considering the limitations of most computer headphones/speakers.

The differences in frequency aren't that significant.  I doubt it would be a problem.  I was able to pretty easily tell the difference in pitch at 1.5 Hz with a $15 pair of headphones.

[Chavo]

IIRC our hearing capability should detect changes in sound on the order of 1dB.  Again, IIRC, most cheap headphones can only handle changes of about 3-4dB.

I don't think that decibels are 1:1 with Hz, though.  I thought it was the log of power and intensity or something like that.  It's been a while since I've looked at that stuff.

[Chavo]

yea, I wasn't trying to suggest a linear relationship with frequency.  I've tried to reword what I'm trying to say a few times and still don't think I'm saying it right, so...meh.

[Towelie]

80.6 on the tone deaf, and .75 on pitch
my speakers suck too much to do good on the pitch test

Decibels (dB) is intensity/loudness, while frequency (Hz) is pitch.

[Sidoh]

Decibels (dB) is intensity/loudness, while frequency (Hz) is pitch.

A decibel is a way to measure "loudness."  Saying it is intensity/loudness is sort of like using a word you're trying to define in a definition.  Furthermore, a dB is dimensionless.  It's just a number.

The measurement is defined in several ways, but they all include a base 10 logarithm of a ratio between some measured number and a reference number.  A common example is intensity:



I_0 is usually defined as the "threshold of human hearing."

More accurately, frequency is the number of cyles a wave has per unit time (Hz is cycles/second).  If you have a pressure wave moving in air, it's the number of full cycles that pass a fixed point in some given number of time (again, usually 1 second).  It's also the inverse of the period, which you'll probably be able to deduct (if you didn't know already; I sort of expect you do, since you like sound and all) is the amount of time that passes during one cycle of the wave.  Pitch is kind of... the perception of frequency.

[GameSnake]

Very neat test! I need to know pitch differences when I tune my guitar.

Yeah, I thought you were trying to say something else.

[GameSnake]

A lower pitch has longer, more slow waves waves, while higher pitch has shorter, more frequent waves.. It's elementary really.

[Sidoh]

A lower pitch has longer, more slow waves waves, while higher pitch has shorter, more frequent waves.. It's elementary really.

A lower pitch can be directly inferred from a low frequency, yes, but the velocity of a pressure wave in air (speed of sound) is constant if the conditions it's traveling in are constant.

Like I said "pitch" is the conception of frequency.  I still don't think you know much about waves, which you've seemed to demonstrate here.

If I'm thinking of the right thing, an example of this is talking after you suck up helium. Even if the wavelength is exactly the same, helium, being a lighter gas that moves more quickly, will result in a higher pitch.

Yeah. 

However, the speed of sound in a substance is relational to its density, not weight.  This is why the only quantative way to define the "regular" speed of sound must involve a temperature.

[Chavo]

note that v in that equation is the wave speed in a vacuum, frequency is constant for a given wave (the wavelength changes proportionally).

Yes, Watson. Quite elementary, indeed.

[MyndFyre]

I didn't have the patience for the first test.  On the second, I got 0.525 Hz.

Of course I was a musician for 9 years of my life, including a year in college, where you need to be able to do that kind of thing...

No I dont much about waves.. If you know so much about everything what do you plan to do with yourself? I know chicken salad from chicken shit.

Can you explain the difference, please?  Because last week, I had a bit of an incident.....

Just dont eat the soft, brown colored material that smells foul and you'll be OK.

Software engineer.

You said it was elementary, which seemed to "imply" that you knew what you were talking about.

So avoid KFC?  Got it.

Chicken poo/KFC might be the same thing.

[Sidoh]

I like KFC.

I wouldn't advise insulting it, though.  Deuce might kill you in your sleep.

[d&q]

Haha, I'll probably just rape you while you're awake.
