Sound-based monsters

[DMrevenge]

Trying to do some brainstorming here. For an adventure I need monsters (from any sources) that are sound-based, sonic-based, or otherwise have sound-based attacks. Anyone have any ideas?

So far, besides NPC bards, etc. I have

Harpy
Vrock Demon (Screech attack)

 

[Knight Otu]

Let's see, just from the MM for now:
Allip (Babble attack)
Cloaker (Moan attack)
Destrachan
Frost Worm (Trill attack)
Fungus, Shrieker (aka living alarm)
Ghost with Frightful Moan ability
Gibbering Mouther
Guardinal, Leonal (Roar attack)
Howler (Howl Attack)
Krenshar (Su Scare attack)
Shadow Mastiff (Bay attack)
Yeth Hound (Bay attack)
Yrthak
