[QUOTE="houlahound, post: 5441035, member: 551046"] explain the question by example; I hit a piece of wood with a mallet and record a pulse ie; [ATTACH=full]98996[/ATTACH] zooming in I get a specific frequency; [ATTACH=full]98997[/ATTACH] pretend it is a sine wave of frequency 500HzI then beat the wood with a frequency of 10 000Hz (pretend this is a 10 000HZ sine wave beating; [ATTACH=full]98999[/ATTACH]so what is the frequency of the sound 10 000Hz? all sounds must be produced this way ie something being mechanically struck eg speaker cone moving under varying magnetic field but you also have the "internal" sound of the structure being mechanically struck eg speaker paper, proof; replace the paper speaker cone with a plastic one and use the same source frequency you get a different tone but same frequency. so which frequency are we quoting?
