microphone mounts

I was at Klaus's forum

Interesting thread

I have been thinking about microphone mounts for sometime and Wonder why they are made the way they are.

The one in the link seems to move the mass of the complete system up alot.

Damper systems are mass, dashpot and spring at the lowest level.

The one system that seems like it might have the best control is the one in the AKG solid tube and it looks like in the new 414. Four O rings that hold the capsule and damp it. The capsule can be a known mass and the O rings materal changed for damping and the tension on the O rings for freq adjust like guitar stings etc

reading that is pretty funny...

I spent maybe a 7 year period or so listening to mics for 12 hours a day, week in week out, without ever using a mic stand attached to the floor-

Shock mounts are obviously critical, but in the case of a boom operator holding a mic on the end of a pole, the majority of the noise comes from the cable, not the pole, not the mount. Mixers and boom ops have been banging their heads at this one for years, the problem is ten million fold from a mic on a stand in a studio to the mic in someone's hands on a pole having to be moved around non-stop. The different boom ops Ive worked with over the years each have come up with their own little tricks but if you are trying to really effectively cut down on noise, you cant overlook thhe cable coupling. Scodidly brought it up and I'll bet that nobody even comments on it over there...

Id be into buying one of those mounts when I can afford it, could be interesting. Anyone who has ever mixed a movie knows full well how little shock mounts for mics actually do. Yes they help, but thats all they do, help, they dont solve the problem anywhere near %100, they just bring the situation into "workable" conditions.

I had a chance to try some of the SabraSom universal shock mounts and I was pretty impressed. This one:

They worked great and I could fit basically any mic in there.

Gus, never seen the Solidtube innards:

Number 1 in pic, that look right? Seems like it would be effective, isolating the smallest mass possible. More quantifiable.

Gave me an idea... to lose the U support... a mini capsule shock-mount, like the old carbon mics, with rubber bands. Have to mess with that.
Thanks for the ideas.

Internal shockmounting is really difficult, because the actual capsule is usually rather light. You end up with something really floppy if you even manage to get the resonant frequency low enough.

Edit: of course the shockmount is the easy part even there. The hard part is finding wire light and limp enough to connect to a capsule without transmitting mechanical noise.

a little off topic...when I used an M7 from a faulty gefell 711 in my G7 mic , I first mounted it in a mount from a common chinese tube mic.
When hooked up, the capsule made no sound? I then put it on it's original mount from the gefell and it worked perfect! It's original system is a shaft screwed into the capsule that slides down inside a shaft part and parcel to the base of the capsule mount.The wires are inside the shaft. What is the deal here?
