Foam affects recorded voice
Reviewed in Australia on 15 May 2020
I bought this to try it and to use as a frame to hold a felt layer that I've tested separately if it doesn't do a good job on its own - and it didn't. This filter comes in two layers, and outer metal frame and an inner foam layer. I expected the foam to be detachable to allow the user to experiment with the foam layer, but it's glued to the metal mesh and I had to pull it off. The metal mesh is just the type you would find on a window screen and doesn't have any effect in blocking plosives as in expensive mesh filters. The foam layer on it's own does dampen air flow and reduce plosives, but it also affect the character of voice, so it's not perfect. This is known about foam, and a pull-over style foam shield would've done the same job without the need to a mesh.
In any case, I ended up using the thin felt I've mentioned earlier. It's used for crafts and comes in colours. Two or three folds inserted inside the metal mesh framework does a good job in blocking plosives without affecting voice characters. My job would've been easier if the foam was a detachable layer rather than having to pull it off and glue another material in it's place.
