Thought this might be a handy reference for some members.



Another interesting reference:

can i just ask, how often do we listen to music that has frequency above 10,000hz? what is some example of sound that is above that freq.? does Luciano Pavarotti reach above 20,000hz?

i just thought it would be useless to adjust the PEQ for frequencies above that range if we dont even get to hear those freq. band....

I'm trying to find a more detailed chart, but in the mean time this will do.

hmmm interesting!!

[Mike_McT]

since he's only a tenor...probably not

frequencies produced by cymbals, especially bright rides can reach up into these frequencies (obviously not the core frequency of the cymbal, but harmonics and overtones)

Thaks Marc - I was trying to find that first graph just now - but missed this thread. Good on ya for making it sticky.

[fortresshill32]

stupid me, no wonder i dont hear any difference when adjusting the peq at 20,000hz.

aaawesome.

been looking for a breakdown like this for a long time. great guide upon which to get your system sounding brill!

very true... wish it had some percusion tho.. as that has the brightest and the deepest tones.. (my zildjian z custom mega bell at home gets so bright it aint funny... and the avedis sweet rides are worse) down to the big 24" bass drums goin around... but ill get over it...

I think the most audiable range for EQ if you want to make your top end sound more open is in the 16K to 18K center frq in parametric. beyond this you really need a super good tweeters to here the diffrernt and only youngster may here it. the older people might not be able to here up to this range subject to age and health condition.

too true. the owner of the hifi store i used to work at had very golden ears... well respected golden ears. but his top end didn't exist thats why he loved his metal domes and ribbons... they compensated somewhat for his age and hearing condition.

From the Pioneer P9 Manual...

20-40Hz - This sound range feels almost like pressure on the ears of the listener, particularly if the sound is too strong.

40-80Hz - In this range, the listener feels they have heavy bass. This is also the range in which the impact of the sound is felt in the body. Excessive sound in this range will impair the clarity of the overall sound.

80-200Hz - The sound range required for bass. A lack of sound in this range results in a weak bass impact, while excessive sound will muffle the overall sound. A clear reproduction lends depth to the overall sound.

200-800Hz - This is the sound range in which the signals are most dense and where the sound outline is created. A lack of sound in this range results in a lack of warmth. Excessive sound dims clarity.

800-2kHz - The sound range required for the core of the sound. An important range for keeping the overall sound quality in balance.

2k-5kHz - In this range, the sharp, expansive sounds of the brass and electric guitar are felt. However, excessive sound in this range is tiring on the ears.

5k-10kHz - This sound range add colour and gaietyto the overall sound. A lack in sound in this range will result in a muffled overall sound, while excessive sound will enhance the metallic aspects.

10k-20kHz - This range is required for the glamorous sound of the cymbals. However, this range does not contain the basic frequencies of almost all the instruments. Therefore, if the sound in this range is lacking somewhat, the overall sound quality will not deteriorate markedly.

Even if you can't hear those upper frequencies your skin will still pick them up as a Psychacoustic Effect. It all adds to the realism. Why do you think SACD and DVD-Audio go right up to 40Khz and beyond? Because it sounds more real! You can test this for yourself. If you walk into a room with a TV on with the volume down, you immediately sense that it is on, even though you can't hear it. An extended frequency response is very important and has been known in home stereo for several years now.

tv oscillator is only 16kHz

but yes, we do 'sense' frequencies above 20kHz - in me it sounds like a buzzing in my head when loud @ ~20kHz
