Under hood blanket

The fiberglass blanket fell off the hood and onto the engine. It is not reusable. Are these worth replacing? I can understand they would insulate the hood thermally, but do they deaden the engine noise? I do seem to hear more engine noise than I remember previously.

What is used to replace them?

Thanks,
Bernardi
