View Full Version : Headset Microphone - Buzzing.

My headset microphone seems to have just started producing an annoying buzz - it's very prominent when I turn my volume up but just at a normal volume level it's very quiet. Another thing I've noticed is that it goes away when I turn microphone boost off, which is not an option. Also when I place my palm on my computer the noise goes away.

Can anyone help please, I've had a thumping headache for most of the day and I believe this is causing/not helping it! :(

let me get this straight - the buzz is in the speakers, or the mic?

whichever way, its just a electronic interference being caused by the microphone boost - which gets grounded when you put your hand on the desk. There's not really anything that you can do about it to be honest. At least not as far as I know.

The microphone makes the noise ;) - and ok, my dad was doing something today with the lighting, changing a switch or something, I wonder if that has caused electrical interference all of a sudden =/.

well - microphones generally aren't supposed to make noise to be honest. It sounds as though there is actually interference coming from the headphones. Both devices are the same basic thing to be honest - a cone that vibrates with magnet on the backside that moves back and forth between a coil of wires. In this way, the sound is turned into electric signal (or the other way around). A set of headphones is useable as a mic, and a mic is useable as a speaker.

When your headphones volume is turned up, the signal strength is increased - causing greater interference to the microphone. That's why i don't like all in one devices - the wires are too close together and are most likely not shielded.

We have a misunderstanding - I mean it's the microphone jack that is causing the noise, when unplugged the noise does not happen. Going to bed now, hopefully by tomorrow morning everything will be grounded and I will not suffer from electrical interference (fingers crosses aye?).

eh? the JACK is making sound? how is that even possible?

Laura, this effect caused by static/induction provoked in speakers by the microphone. When you place your hand near it works like antenna/shield and reduces induction effect. My advice will be: enlarge the distance between mic and speakers and their wires and better turn off Mic Boost.

Also may check if your power outlet is properly grounded and well wired, loosen zero connector can cause this humming sound aswell. Degauss you monitor if you have CRT type.

Aha, I give up, I am the worst explainer.

Yeah I know how it is caused - but I could not understand where it would be coming from because nothing had changed and I have not got any speakers ;).

My theory worked, there must have been some kind of built up static, seeing as this morning it has gone. :)

Sorry to double post but I just found out I only get the buzzing sound when the light is on downstairs - the light has not been working for ages, so my dad has changed the fuse in the main fuse box thing for the house. I cant just expect people to not turn on the light - how could I possible solve this conundrum :p ?

Search faulty zero connection from the fuse box further on to the lights downstairs (Places to look: fuse box, lights switch, the bulb holder). Well, actually, better a specialist do that ;)
