Wierd buzzing noise from grille near interior light....

[Beefmeister]

My 172 has started making a wierd buzzing noise, almost like interference, from the little grille just ahead of the interior lights when the engine is started.

Does anyone know what this is?

Its kinda irritating and appears to be getting louder.

Don't want to take it to the local Stealer as that's Toomeys and they're shocking...
