I'm only making an assumption here but i'm assuming that you may be confusing that with the sample rate at which we record audio to a digital device 44kHz being twice frequency (minimal sample rate required to reproduce the original signal, ie. the Nyquist Rate).Anonymoushttps://www.blogger.com/profile/17122677042469235366noreply@blogger.comtag:blogger.com,1999:blog-1427815439361646147.post-31709669427049814212014-02-14T05:15:21.203-08:002014-02-14T05:15:21.203-08:00Ultra sonic welds are at, well, ultrasonic frequen...Ultra sonic welds are at, well, ultrasonic frequencies: 44kHz and above, which is out of hear range for us humans anyway.<br /><br />good way of pinpointing a fault.Anonymoushttps://www.blogger.com/profile/16736744871827528255noreply@blogger.com
