[QUOTE="rachalmers, post: 1824053, member: 402263"] Interesting problem.:-) Lets see. Do you still get the sound if the computer is somewhere else? I mean, unless you live in a one room apartment. Put it in another room. Is there any ozone smell generated with the snap? (Electrical) How loud is it? You can hear it across the Room? Across the street? A wireless transmitter near you? Ham radio type thingy. They can cause mayhem if the antenna isn’t tuned properly. I once had a bare speaker sitting on a window sill not connected to anything, and the neighbours ham radio transmissions were coming through it, until I told him. Which is why I mentioned it a few posts back. A speaker doesn’t have to be connected to anything to be able to pick up emf, if it’s a traditional moving coil speaker. Piezo of course doesn’t do it. Your audio equipment won’t pick up that stuff because it’s almost certainly shielded and earthed perhaps. I don’t think I’ve ever seen a computer with shielding. Do you have it plugged into a surge protector? Even better a battery standby. A UP, an uninterruptible power supply. Let’s face it, the only thing that can create a snap like you describe is metal moving. Expansion/contraction, or something electrical discharging. If your speaker is disconnected will you hear it. If so... it’s one of those two. The case or some part of it heating up and snapping as it cracks into place, or something arcing. In which case you will smell the ozone. Unless you are a smoker then of course you’ll be lucky to smell anything! Sent from my iPad using Mac-Forums [/QUOTE]
