similarly, under stress your computer may change the operating voltage/frequency of the CPU. this can change power supply behavior, which typically operate at lower frequencies than the cpu itself. .  In some computers this has been noted to create a change in faint, yet perceptible, high pitch audible noise, as the human auditory range up to aronud 20kHz.

in any case, unless you're getting deliberate sounds created by the software (think pc speaker beeps, etc.), there's not much Octave can do about this. 

Here are some more things you can read about pc hardware noises to see if they provide any insight into yours:

Assuming you're not referring to software generated noise, there's not much Octave can do for your concern.  closing report.

Check your CPU cooling fan. Maybe its bearing has gone. This test will drive up your CPU temperature.

Test:
for x = 1:100000
  A = B^2:
end

where A and B are 1000x1000 test matrices.

It makes a funny sound inside the computer like a high pitch hissing. The noise stops when the code stops.
