Can you hear the differences between a square wave and a sine wave

Square waves are associated with clipping and too much power under the curve - voice coil changes from copper color to a darker color before failure of speaker ( also, aroma of voice coil is sensed via olfactory or sense of smell )!

Thank You , Mike !

Might help some , as far as replacement of speakers after they get burned up $$ U need to turn it down !

Harshness is heard by many , sometimes it is laid on speakers . If your amplifier's gain is turned to right or up , excessively , the noise floor is raised to unacceptable levels [ solution - buy an amp with more power ].

Learn the sequence to follow when setting gains , correctly.

When clipping causes power compression [ speakers sound 3 dB's quieter ] . Some just turn volume knob to the right , not good !

If you listen for extended periods of time and your speakers seem to drop in output level [ Time to quit ! " for that session ].

How high can you hear a difference , and is this helpful ?

Do you understand the difference between a sine wave ( gently undulating or rolling waves ) and ( square waves where the top of the wave has been clipped off and you are left with too much under the curve ).

Time to buy new speakers

At subwoofer frequencies - 10% distortion is exceptable to a large number of people . [ 20's - 80's hertz ] At midrange frequencies distortion is easier identified and found objectionable. [ 100 hZ - 2 khZ ]

Hopefully , you can distinguish between square or " clipped off waves " and the sine waves.

At a high enough frequency the waves sound similar. some or few people can hear above 20 khZ

Dog whistles start around 23 khZ !

:happy:

Some tweeters claim to play frequencies well above 20,000 hertz. Since I can't hear those frequencies and I have seen tweeters that claimed 50,000 hertz [ super tweeters ] , never was interested in em .

From 9,000 to 20,000 = silence to my hearing , how about yours ?

made it from 20 Hz to 8,200 Hz on this one before it went silent . . . HOW HIGH - can you hear up to , post and let us know , p l e a s e !

:daniel: :eekfingerd:

160 views and not a single response . . . WOW !!

Shite all sounds the same - SISO or shit in shit out

No one wants to let us know ?
160 views ???

Take a test and post your results ... Please

[ SIZE=6] Post how high you can hear[/SIZE]

Using headphones, I heard 20 to about 18,400Hz

or until 5:55 on the video

Al's hearing is Great !

Anyone, top that , post your results unless you are skeered/afraid/ashamed . . . et cetera.

Who here has " Golden " ears ?

I couldn't hear anything past about 14.2kHz, went to dead air. My left ear stopped sooner than my right as I expected. Sadly, with tinnitus, I can hear about 8k all day long, with nothing playing LOL

I need to try this with headphones....and when I'm not sick LOL

Youtube kind of sucks for this kind of video. On the last video posted if you watch it at 360p the audio cuts out right at about 15khz but if you watch at 720p I can hear it just past 17khz. Using test tones I can hear a little past 18k though which is surprising given the amount of abuse I put my ears through.

Glenn, I can relate , ears always ringing !

I only ever met one person who "appeared" to hear above 20,000 hz based on description of what they could perceive .

my concerns in any testing regimen, starts backwards from the last thing in the chain to the source. This means I suspect many headphones of not producing the tones, evenly where I can say "yep, drifts out right about ...." and if I can't trust my headphones, then I'd have to calibrate them against known quantities. Audiologists are supposed to be able to provide the tones, but I don't even know if they guarantee their delivery system above 17Khz, something I do not know, and can't afford to pay to find out.

if the source is already suspect, as in what setting resolution determines what top end the media pushes into the amp/dac/dap, like said in youTubo, then I certainly wouldn't give this well-meaning thread the headspace it deserves based on at least 2 magnitudes.

you know, how a magnitude can be.

I used a cell phone cajunner and I listen to speakers in many forms.

This is a test which could reflect on your ability to hear and iffn you want people to see you at your best this might not be for you. In that instance I would post the most expensive set of cans that you know of as your own and claim another thousand or two hertz. In other words LIE

that's right, I certainly wouldn't admit to not being able to hear anything above 15Khz, if that was the case, heh..

and even if my headphones, or IEM's were rated by professional testers to put out an easy 20Khz of plus/minus 3 db, I'd probably be uneasy about the cost since I shouldn't admit I've only dropped a c-note or less to obtain the pseudo quality...

it would also seem as though my ability to discern, is now called into question because my square wave almost sounds like a sine above 6Khz or whatever, and that can't be right, right?

I hate to admit it but either these listening tests are contrived to cause consternation or I just am not all I crack up to be, and I know that goes for the rest of you not quite golden ears hiding in plain sight, on these wanker threads.

It's no small matter to try to escape from nobody tedium to rise above, and make those lofty claims of "I can hear this brand is mostly snob-biased, and this other is the truth" when they came off the same factory floor, different shift in some Chinese mega-conundrum, yesterday...

seems to be a bit shady, lady.

but that's okay, I don't get quality reads anymore because some people think I'm not fit for public consumption, and make unilateral decisions regarding my rights to an opinion, even as they heavy hand all around.

If it is , you have not been kind to your ears ( Loud sounds may have damaged the cilia / gun blasts/chain saws/lawn mowers, et cetera. )

oh, I have lived, in the hot zone of seismograph recorders and using dynamite as functional drill water pit manufacturing, no hearing protection aboard 350 Chevy powered airboats, not to mention centerfire rifle use, along with the obvious rock and roll concerts and assorted attempts at their replication inside various car envelopes...

so if I level match a 6 KHz sine to a square, and for the sake of equivalence pit a concentration of effort at identifying one from the other, being right without the prerequisite "gut check" cheat of prior study using my test tone practice for "legitimizing" the outcome, then yes...

I could fub that particular answer in a rigorously controlled examination...

hahaha...

it doesn't matter though.

the oddity is not my own, we are all blessed with these imperfect devices that came from nature, vs. nurture. Oblivious as a teen, twenties exercise in not caring, no.... not understanding the satiety mark of volume levels against my apparatus, as we might all be guilty I am preponderant of more, guilt...

so let this be my stance against the golden ear, I am excited by sensitivity indirectly masking an acuity deficit, which might altogether rend a response that matches or even copiously exceeds the golden ear and their taunts in discerning, nearly everything audible to me.

and isn't that a nice island to create, a space where my fubar hearing gains reverent pose, why should it not?

I believe I am fully capable of deciding what is superior and what remains, the also-rans of yesteryear, based on precious few auditions, based on precious few funds to receive auditions.


I don't expect many of you to be entertained, energized by a wordy boy, but for me it is just my shining, in glimmer-vacuums.

see, it is me, and not you.

but you are okay, just in case it appears I have not afforded that much, to you...

Thank you, cajunner !

I know the sound of an airboat , also. They put a 502 caddy engine in and it had a beautiful wooden propeller.

you are welcome, Hic.

I am not too full of myself to show defect, even if doing so jeopardizes every opinion in discernment I choose to expose, such is the case that I am as open a book as I can be, here in the anonymity of interwebbage.

so many people hide behind their pride-filled personas, making themselves superhuman in the process. It's hard to be superhuman, if you're not. That's kind of stupid as a floated opine, but you know yourself that the most direct path to the center of any controversy is hardly the most traveled.
