A background rumble appears in a sound from microphone in Sound blaster Live.

[D]

Perhaps the sound card just has the problem that it's a Soundblaster
Live! and you're using the mic input. A SB's Line in/out is
acceptable quality but the mic input is a joke.

Thanks Richard Crowley and Laurence Payne for your explanations!
A Sony ECM-T6 microphone and another desk-top microphone don't hum! A
new Koss sb/45 headset and Philips SBC HM300 headset hum from their
microphones.
How to make Koss sb/45 headset microphone work?
Best regards,
Dima

 

[D]

You're welcome and good luck. Check if a new sound card isn't
cheaper than fixing yours!
Creative is basically OK and ultra-compatible although
perfectionists complain about the sound/specs.
M-Audio if you're a musician or have very good ears.
Turtle Beach is pretty good too if you can find one.

How can the speakers amplify the hum of the little power wart if they
are disconnected by the insertion of the head phones?

The speakers are only disconnected from the audio source, the "wall
wart" is still powering the speakers amplifier. Try turning the volume
knob down or unplug the speakers little power supply.

IIRC, any Sony mic with the prefix ECM is a quality product -
although even Sony is not what it once was, sadly. That used to
be a prefix for their professional mic line, but that may have
changed.

Nothing which is NOW called professional IS - if it says
"professional" or worse, "professional quality", DON'T buy it.
If it's professional, you'll know it by where it is sold and how
much it costs. All "computer" microphones, headphones, and
speakers are TRASH and always will be.

Koss was a very good brand 35 years ago. It is trash now. The
name was bought by some jerks - like it has happened with MANY
formerly good brands - and now they sell junk with a formerly-
good brand name on it. Put it in the garbage where it belongs.

If you want a decent headset/mic combo that will work properly
and does not have wires inside touching where they shouldn't
etc., you will need to spend a fair bit of money. I am talking
Sennheiser, Beyer, etc. Hundreds of dollars. NOT made in China
shit.

Much cheaper to get a gooseneck desk stand for your mic and use
the 2 separate devices. Easier on your head physically, as well,
and doesn't get in the way of enjoying your coffee or vodka. (Or
both together.)

Why does the hum appear from a headset microphone only, not from a
separate microphone?

A table stand microphone requires to keep a mouth in one place, 2
centimetres from the microphone all the time to catch minimum
background noise. A headset microphone does not require.
Why does the hum appear from a headset microphone only, not from a
separate even small and cheap microphone?

OK but this is my LAST reply.

A GOOD unidirectional microphone (like possibly your Sony) does
NOT require anything like you describe. 5-10 cm is more than
sufficient.

A gooseneck can be moved VERY easily, the best way is to screw a
flange mount directly onto the desk (they're about $3) and screw
on a gooseneck of your preferred length (with a mic clip) on the
end on to the flange.

A good gooseneck is very stable, and $25 is certainly better
than $200 for a medium-good headset, IMHO. But maybe you're very
rich. I have heard things about the Russian Mafia ;-)

The reason your headsets HUM is because they are CRAP and wires
are not properly isolated from each other. Borrow a $350 one
from a radio station or a DJ or something and you will find out.

ANY set of walkman/iPod head/earphones and a decent
unidirectional mic is the most cost-effective chat (or whatever)
setup.

If you don't like goosenecks and don't want hum, get a $400
Sennheiser headset and a $30 adapter so you can use it with your
sound card.

Over and out.

t.

The confusion comes from the misuse of the term "speaker". The sound
producing components in a headset are called "headphones" or "earphones"
not "speakers", the condition I described applies to powered speakers
not headphones or earphones.

The ferther a mouth from a microphone the smaller a difference in
volume between a sound from mouth and a background noise.

Hello!
The headsets hum from their microphones even through another sound
card Creative SB 16, although they do not hum on another computer.
How to prevent the hum?
Best regards,
Dima

 

[Martin Harrington]

Aren't we over this discussion, it really isn't one for a pro audio group.
Please stop cross posting.

Maybe is just that that's all you can expect from a $50 gamer
soundcard...

No, the soundcard works well with a separate (not in a headset)
microphone. Another card works the same.

Because the power is not being supplied by your PC?

How to make microphones without a battery not hum?

By making sure the card & microphone are fully compatable & that
you're not pushing your PC power supply to the limit as they tend to
get a little unstable if you continually do.

Because the battery is independent of the mains power.

That confirms that the problem is coming from the mains-
derived microphone power coming through the sound card.

How to make microphones without a battery not hum?

Replace the sound card with one that works properly.
(Or just continue to use the battery.)

There are no microphone requirements on the Creative site for SB live
or 16.

I have two cards: SB Live ct4830 and SB 16 PnP. They both hum from a
headset microphone.
