Problem with PA Microphone picking up turbulence from the lecturer’s mouth

[Agharta]

I’ve been going to a venue where various people speak and it’s clear that the microphone is picking up the air turbulence from their mouth unless it is held at a good distance from their mouth and at chest level.
I’m sure there’s a name for this and whatever it is the effect is very distracting to me.
As there are different people each week and they may well forget even if told how to hold the microphone I’m wondering if there is a simple way to address this at source, a foam Mic cover maybe?
It’s a hand-held wireless microphone and the size is medium to large and looks something like the below image.
I haven’t measured it but wondering if something like this would help?

Help appreciated as if this isn’t sorted I will likely stop attending. I’ve spoken with them but they aren’t very clued up so I will need to present a solution. Thanks.

Sounds like you are talking about 'plosive popping' which is caused by poor mic pavement or poor mic technique, in combination with a directional (pressure gradient) mic and ineffective wind shielding.

The easiest way of improving things would indeed be to attach a foam windshield of the type you've suggested (but do check the size is suitable first). The thicker and larger the foam, the better... Although there will also be a slight reduction in the very high-end response.

Thanks Hugh and I was sure there would be a name for such a commonly occurring thing and what a great name it has.
Plosive popping sounds like something I did as a toddler!
I'll try and measure it in the week coming and order a decent quality one.
