Non pitched sounds are sounds which are not only composed of a fundamental frequency and a distribution of its harmonics. That's quite a strict definition of 'non-pitched'. Most sounds that are essentially perceived as pitched by humans nevertheless contain energy at frequencies that are not exactly at the multiples of a fundamental - possibly because the ...

I think you are confusing multiple concepts. As piiperi Reinstate Monica stated, the example you give would be 2 pitches rather than a non-pitched sound. The term non-pitched usually refers to percussion instruments, percussive sounds, scratching, and other "sounds" for which it is difficult to define a fundamental. I think you got that part ...

Simultaneous sine waves at 440 Hz and 500 Hz are some kind of a two-note chord, or an interval at least, something like a major second. It's definitely pitched, because there are two distinct constant pitches. If you cannot identify a pitch, then the sound is unpitched. I don't know if silence counts as a sound, even though there's a song about it, but at ...

If you ever have a chance to play a very large pipe organ, give it a try. You will have difficulty playing until you get used to the latency of several tenths of a second. The 10ms figure was determined about 50 years ago when a new keyboard design was invented. In this design, currently used for computer keyboards and most music keyboards, the keys are ...

The experiment was a multi-octave (five or so) C followed by a multi-octave F# (or Gb). Actually, any augmented fourth or diminished fifth will work. Some people (supposedly) hear one tone as higher and one as lower. (I noticed a multi-octave tritone but couldn't tell which was higher; I don't have perfect pitch.) I'm now sure why this should work unless one ...

When you stop to realize a rock and roll or country music stage is often 40, 50 or 60 feet across the front of the stage, you might expect that latency between performers might become a real problem, but when every instrument is miked up or D.I.ed into the sound system and mixed the resulting sound has no noticeable latency between instruments because ...
