Well, it can be useful to try understand meaning of words.
According to dictionary:
"Hyperbole is the use of exaggeration as a rhetorical device or figure of speech"
Rhetorical device = for example using exaggerated metaphors ("comic swirls...").
Does metaphors work out, is entirely different case. And that do we seek scientific and rational language, or language that awakes ideas and feelings - like material it describes?
Using regular adjective (like filthy) is hardly "exaggeration" of any type.
Filthy, according to dictionary:
1. Covered or smeared with filth; disgustingly dirty.
2. Obscene; scatological.
3. Vile; nasty
In context of noise or PE, this word simply carries plenty of meaning what sums up certain type of stuff - it's sonic quality or presentation - very well.
Word I often refer with certain type of noise is crude. And what's that?
1. Being in an unrefined or natural state; raw.
2. Lacking tact or taste; blunt or offensive: a crude, mannerless oaf; a crude remark.
3. Characterized by uncultured simplicity; lacking in sophistication or subtlety
4. Not carefully or skillfully made; rough: a quick, crude sketch.
5. Undisguised or unadorned; plain: must face the crude truth.
6. Statistics In an unanalyzed form; not adjusted to allow for related circumstances or data.
7. Archaic Unripe or immature.
And that again covering great deal of works out there. One simple word, and it covers plenty from aesthetic choices to technical qualities.
Of course, as writer, one would have to consider, does reader know what you try to say, if you gather load of information in one word. Lets say, what exactly is "menacing" noise? I know what word means, and I know how I would use it - and in what purpose, but I see it used basically attached to any type of stuff.
I have been thinking of resurrecting that old "language of noise" topic - and this kind of nerd talk probably fits there better, hah!
