While we can't hear above 20khz, any sound content above 20khz could interact with other sounds and the resultant interaction create sound that are the difference between the 2. For example, 20hkz and a 22khz interacting together would create a 2khz beat freq. Whether or not there is enough energy in this signal that could affect the hearing would be difficuilt to say.
The importance and effect to and above 20kHz...
Hi Everyone -
I was wondering if anyone would care to elaborate on the importance of system frequency playback as the frequency range approaches and passes 20kHz. What effect does 15kHz have on music, for instance, and why is it important to keep the upper frequencies as linear as possible? How about 18kHz, or 20kHz, or 25kHz? What effect can these specific frequency regions have on the overall performance, and why should I keep them linear?
Let me clarify, I used those particular frequencies as examples, but if they can be expounded upon, then go ahead. I'm hoping everyone understands what I'm trying to get at. What effect can the upper treble frequencies have and why is linearity in these regions so important? Same goes for above 20kHz, say in the 22-30kHz region.
Can anyone explain?
Thanks for you help.
