Could you guys tell me some sounds that are typival above 3 kHz in musics and movies.
The top four white keys and top two black keys on a typical piano are over 3000 hz. The highest F# (third black key from the top) is at 2960 hz. The next note (G) is at 3136 hz.
Voices - Fullness at 120Hz; Boominess at 200 - 240Hz; Presence at 5kHz; Sibilance at 7.5kHz; Air at 12 - 15kHz.
Harmonica - Sounds "Fat" at 240Hz; will add "Bite" at 3 - 5kHz.
Conga - Resonant ring at 200 - 240kHz; Presence and "Slap" at 5kHz.
Bass Guitar - Attack or pluck is increased at 700 or 1kHz; Bottom will be added at 60 or 80Hz. String noise at 2.5kHz.
Bass Drum - "Slap" at 2.5kHz; Bottom at 60 or 80Hz.
Snare Drum - Fatness at 240Hz; Crispness at 1 - 2.5kHz; Bottom at 60 - 80Hz.
Hi-Hat and Cymbals - "Shimmer" at 7.5 - 10kHz; "Klang" or Gong sound at approx. 200Hz.
Toms - Attack at 5kHz; Fullness at 240Hz.
Floor Toms - Attack at 5kHz; Fullness at 80 or 120Hz.
Electric Guitar - Body at 240Hz; Clarity at 2.5kHz.
Acoustic Guitar - Body at 240Hz; Clarity at 2.5kHz; Bottom at 80 or 120Hz.
Piano - Body at 80 - 120Hz; Presence at 2.5 - 5kHz; Crispness at 10kHz; Honky-Tonk sound at 2.5kHz as bandwidth is narrowed. Resonance at 40 - 60Hz.
Horns - Fullness at 120 - 240Hz; Shrill at 7.5 or 5kHz.
2kHz - 4kHz Speech recognition = 3kHz (Results Of Excessive Boost Listening fatigue. Will add a lisping quality to voices, "M", "V", & "B" will become vague.)
There is nothing that Phil doesn't know!
I think Phil must read ALOT!
We'll stump ya one day Phil....
Dave why do you ask?
I'm guessing 3 kHz is where the crossover is in his speakers, and he wanted to know what kind of sounds the tweeters are putting out.
That is correct Richard. By the way can you damage tweeters if your amp clips. I do not mean destroy but alter there performance in a negative way. Or is it more a all or nothing thing. i.e. you blow your tweeters or you do not.
I think the majority of drivers that get damaged is subwoofer drivers. I havn't heard of many cases of tweeters getting blown, or changing sound for that matter.
If you think about the tweeter, it has to move at incredible rates to play frequencies up to 20,000hz. I'd say it's a wonder that they can handle those high speeds, I wouldn't be suprised if they could tough it through some distortion.
