laptop durability

[s2501593]

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.

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.

Nice. Any serious suggestions?

why don't you just use google.

I tried that first, but to no avail. I thought that someone here may have another suggestion...

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.

You have the 20 Pa RMS right, but this is far from true. Look into structure-borne sound and sound radiation from plates.
