I've has a go at revising the introduction. The existing one used some very technical terms straight off. I've tried to produce a softer way in for the general reader. I've also mentioned open- and closed-cell foams, because this is an aspect of foams of everyday importance (whereas the polydisperse

The last paragraph puzzles me. It seems to imply that polyurethane foam, polystyrene foam etc are not actually foams, technically speaking. Is this correct, or is the intention that yes, they are foams, but that they are dealt with in their own articles?

It does not talk about the speed of sound at all, switching immediately to a niche topic of hydrostatic power equipment engineering. Even then, the cited frequencies of 1000MHz indicate that the author has no good idea of what he is talking about.

Lather redirects here, but "lather" is not mentioned. The stuff on the cappuccino is froth (I would have said). How about a brief mention of these other expressions?

In my opinion, the 'Foam scales and properties' tab in the article should be removed as in my opinion it is pointless having an empty tab in the article.

I recommend deletion of the entire content of that section and give links to "speed of sound in composite materials" instead.
