Best microphone in noisy environment

I going to record some interviews in a noise area, it's a exhibition people are talking high.

I have a Sennheiser EW112-p Lavalier Mic. But I get some much noise from the environment, is there some trix or special settings for this mic to reduce the sound?

Or what is the top microphone for got the best audio with high noise?
 
The worst kind of mic to use in a noisy environment at a distance from the mouth is a omni lav - which works great in controlled situations. The best (or at least most often used 'trick') is a hand held omni, very close to the mouth. If you put a cardioid close to the mouth then the bass increases greatly making it sound very odd. You can buy omnis with breath windscreens and long handles that work pretty well close in Electrovoice and Beyer have models that are popular, but there are others too. However, you could easily modify the lav you have. Make up a plastic handle, use a split cork (like they use in wine making) and use this to mount the mic at the top. Then cover it with an easily available foam windshield. You may have to reduce the transmitter gain a notch as it will be close to the mouth, but it could work for you.
 
Interviews during a convention is probably best handled by a handheld interview style mic or a shotgun on boom if you don't want the mic in the shot.

This one:-

Coles_4104_Lip_Mic_hire.jpg

The Coles lip mic. as used by ringside boxing commentators and the like.

It gives clear audio even in the noisiest environments.

But it has to be held right by the mouth with the upper "lip guard" touching the upper lip. :beer:

Not a trick, just the laws of physics, and the laws of physics work the same for all mics. To increase the signal-to-noise ratio, you have to increase your proximity to the signal source. IOW, get whatever mic you're using closer to the mouth you're interested in hearing. Typically a distance of 10cm or less.

At a trade show or exhibition, the most time honored "trick" is to use an omni reporter's mic, like the EV RE50N/D, and have the reporter put it very close to the mouth of the speaker (reporter or interviewee, moving the mic as required). This requires a certain amount of dexterity and of paying attention; some reporters do this better than others. It's not natural and does take some practice. But when done well it works about as well as anything you can do in a noisy environment.

I've used an EV RE50N/D with a Sennheiser SKP-100 for trade show floor interviews with excellent results.
 
I would also recommend a H/H reporters mic. Specifically the Sennheiser MD-46. Though an MD-42, the above mentioned EV RE50 or other reporter's type H/H mics would work too.
You could try a cardioid lav but they are subject to 'off axis' issues like head turns, ect. Otherwise, some omni lavs are 'tighter' than others, I've always liked the venerable Sony ECM-55 for those situations. (if you don't mind the size of it) In addition the SKP-100 butt-plug transmitter could eilininate cables, which is good when there's lot of people around who always seem to get tangled up and trip over cables.
 
I've noticed quite a few time at the games in the noisier places, the reporters talking into the business end of a shotgun in a hairy sausage overcoat - looks really silly, but I guess some locations are just too noisy. I've got one of John's Coles mics here - but it's in mic box c - the one rarely to see the light of day - but if anyone wants some comparison audio I could always dig it out.
 
For ENG/EFP, have you tried the Sanken CS-3e? It does a pretty good job of off-axis rejection and is hidden from the cam. Downside is a good boom op is needed during the interview. Otherwise, typical Shure SM58 is probably the cheapest solution.
 
The short answer is the best mic in a noise environment is the one closest to what you want to record. After that the more directional it is generally the better, though being inside can complicate that.

I am always amused at seeing reporters talking into shotguns and they are the total wrong mic for the situation as the phase cancellation aspects are totally lost and the transducer is at the wrong end of the mic, a Beyer M58 or an EV RE50 are the better choices and the new RE50N/D-B is excellent as it gives extra gain if required.

exactly what Scott said.
Specific mics in my opinion would be
omni lav's
Sanken CS3e
Sennheiser 816
Or any of the standard handhelds if that applies..
