Sound Manipulation
Also called Sonokinesis, Sonic Scream, Vibration Control
Sound manipulation is control of vibration and pressure waves. It is unusually lethal on paper — sound at sufficient amplitude destroys structures and liquefies tissue — and is nearly always given a hard limitation to compensate, most famously a voice that cannot be used at all.
How it works
Emission users generate sound. The ceiling is amplitude, and the counter is trivially simple: block the ears.
Manipulation users shape sound that already exists, including silencing it, which makes them far harder to counter.
Resonance is the top tier — matching a structure's natural frequency to shatter it, which requires precision rather than volume.
Sound powers are almost always paired with a severe cost. Black Bolt cannot speak; a whisper levels a city. That is a design choice, not an accident: an unrestricted sonic power ends most fights immediately.
How it scales
- Emission
Produces damaging sound. Capped by amplitude.
- Manipulation
Shapes and silences existing sound.
- Resonance
Destroys by matching natural frequency.
- Concussive
Weaponised pressure rather than noise.
Who has sound manipulation
Across 3 universes. This list crosses publishers — something no single wiki can do, because every franchise keeps its own separate database.

| Dazzler | Marvel | Marvel Comics | 2 |
| Klaw | Marvel | Marvel Comics | 4 |
| Black Canary | DC | DC Comics | 6 |

The feat ledger
Every entry cites the work it comes from. Feat means it was shown in the work; Statement means a character or narrator said it. Nothing here is a fan estimate unless it is tagged Calc.
Black Bolt — A whisper is destructive enough that his silence is containment rather than discipline
Banshee — Uses lower-frequency sonics for flight and higher ones as a weapon, from one ability
Black Canary — The Canary Cry is a metahuman ability paired with hand-to-hand skill written as among the best in the setting
Kyoka Jiro — Plugs her earphone jacks into a surface to transmit her amplified heartbeat through it, using her body as amplifier and sensor
Silver Banshee — Her scream is written as lethal specifically to a target whose true name she knows — a magical constraint on a sonic power
Klaw — His body is living sound, which he shapes into solid constructs
Black Bolt — A whisper levels a city block, which is why he does not speak
Black Bolt — The quasi-sonic scream is his only offensive technique and is never used casually
Black Bolt — Speaking is written as the ultimate sanction — a plot event rather than an attack
Dazzler — Absorbs ambient sound as the fuel for every other ability
Dazzler — In silence she has nothing to convert, the stated limit on her
Klaw — His body is living sound after the conversion, not flesh
Klaw — Physical attacks pass through him without effect
Klaw — He killed T'Challa's father, which is why the enmity is personal rather than ideological
Banshee — A focused sonic scream shatters stone and armour
Silver Banshee — Her scream is lethal specifically to a target whose true name she knows
Silver Banshee — The scream shatters structures as well as harming people
Silver Banshee — The true-name condition is a magical constraint on an otherwise sonic power
Kyoka Jiro — Earphone Jack plugs into surfaces to amplify her heartbeat as an attack
Kyoka Jiro — Her output depends on what she can plug into, which is the stated limit
Kyoka Jiro — The quirk is a support ability the series repeatedly shows as decisive
Black Canary — The Canary Cry shatters concrete and incapacitates a room
Black Canary — The cry is a metahuman power; her hand-to-hand skill is training and entirely separate
Black Canary — Focuses the cry on a single target rather than broadcasting it
Black Canary — Losing the cry leaves her fully effective, which is the point of the character
Black Canary — The original Black Canary had no powers at all — the cry belongs to her daughter
Limits
- Sound needs a medium — vacuum defeats it entirely.
- Ear protection is a cheap and effective counter to emission users.
- Emission users usually damage themselves at full output.
- Black Bolt's power is inseparable from his silence, which is the point.
Counters
- Vacuum, or any environment without a medium.
- Soundproofing and ear protection.
- Preventing the user from speaking or breathing.
Questions
Why can Black Bolt never speak?
His voice is the power. Even a whisper releases enough force to level structures, so silence is not discipline but containment — the limitation and the ability are the same thing.
