s2501593 Posted February 28, 2007 Share Posted February 28, 2007 I'm looking for a resource that shows laptop durability under high noise levels such as over 120 dB broadband noise over a given time? Any help appreciated. Link to comment Share on other sites More sharing options...
Externet Posted February 28, 2007 Share Posted February 28, 2007 Hello. Durability in hours = CPU speed(in MHz) x number of built-in microphones ÷ SPL (120dB) times the noise wavelenght in metres x Degrees (in Kelvin scale). For chinese built, multiply by the factor K= 0.3165656 Yields a margin of error of 0.4%, quite acceptable. Miguel Link to comment Share on other sites More sharing options...

s2501593 Posted February 28, 2007 Author Share Posted February 28, 2007 I tried that first, but to no avail. I thought that someone here may have another suggestion... Link to comment Share on other sites More sharing options...
Kovich Posted March 12, 2007 Share Posted March 12, 2007 Sound is merely a rapidly time-varying pressure AC component which combines with the DC atmospheric pressure via linear superposition (i.e. they simply sum together). A Sound Pressure Level of 120 dB represents an AC RMS pressure of 20 Pascals (you'll need your industrial ear defenders!). However, as the average pressure of a noise signal is actually zero, then the net force on your laptop will be also be zero. Edit: Which of course means that any laptop will do.
