Maybe it is the will to survive that makes me even more alert to sounds. Sight is limited in this darkened part of the world. In this case their heartbeats. Not my own, but instead the Killers' as they close in on me. I just hope that they do not pick up on mine as my heart races for every thump I can hear even clearer. | 
|
| ~ Benedict Baker's Journal, Nov. 1896 |

Again, my senses have proven to be the keys to my survival. If my heartbeat rings in my ears, the Killer is close. If I see the "red stain" in my surroundings, the Killer is even closer! |

The Terror Radius is an integral Game Mechanic in Dead by Daylight 
.
Contents
Overview
The Terror Radius is a feature intended to induce fear and anxiety in Survivors, causing them to experience The Heartbeat, a sound effect triggered whenever Survivors enter the Killer's Terror Radius and intensifies with proximity.
Terror Radius
For most Killers in Dead by Daylight, their Terror Radius is decided by their base Movement speed: 32 metres for those moving at 4.6 m/s and 24 metres for those moving at 4.4 m/s.
However, some Killers do not follow that general rule and either have a different Terror Radius altogether or even multiple Terror Radii, as can be seen in the Table below.
The Terror Radius has 2 components to it, the Heartbeat and the Terror Radius Layers.
The Heartbeat
The first component of a Killer's Terror Radius is the Heartbeat heard by Survivors whenever they are inside the Terror Radius.
Benedict Baker's Journal confirms that it is indeed a Survivor's own heart that beats audibly whenever the Killer is nearby.
This is further confirmed by a "Mysterious Note" found in the Fog and by the visibly beating heart model in the chest of Survivors used in Dead by Daylight Mobile.
The loudness and pace of the Heartbeat is tied directly to how close the Killer is to the Survivor in question.
Terror Radius Layers
The second component of a Killer's Terror Radius are the Terror Radius Layers.
The Terror Radius Layers are the musical component of the Terror Radius.
Each Terror Radius features 4 distinct Layers, with the possibility to add 2 additional Layers:
| Layer | Proximity from Killer | Use Case | Additional Information |
|---|---|---|---|
| 1 | Far (1st Third) | Terror Radius | - |
| 2 | Near (2nd Third) | Terror Radius | - |
| 3 | Close (3rd Third) | Terror Radius | Replaced by Layer 4 when in Chase. |
| 4 | Chase (3rd Third) | Chase Music | Replaces Layer 3 when in Chase. |
| 5 | Chase (3rd Third) | Chase Music | Added in addition to Layer 4 when 1 Mix Tape Add-on is used. |
| 6 | Chase (3rd Third) | Chase Music | Added in addition to Layers 4 and 5 when 2 Mix Tape Add-ons are used. |
Layers 1, 2, 3
Layers 1, 2, and 3 are used to signal proximity, akin to the Heartbeat.
They divide a Killer's Terror Radius into three equidistant radii, with each third of the Killer's Terror Radius playing one of the three Layers.
Layer 4
Layer 4 is reserved for when the Killer is in a Chase with a Survivor and replaces the third Layer of the Terror Radius.
Layer 4 is also referred to as the Chase Music and is what the Killer will hear when in a Chase.
Layers 5, 6
Layers 5 and 6 are reserved for additional music layers, which are added as embellishments on top of Layer 4 when the Killer is in a Chase, they do not replace other Layers.
This mechanic is currently only used for the Mix Tape Add-ons of The Legion 
.
Terror Radius Music
Older Killers generally use one of 6 available generic Terror Radius Music themes, whereas newer and reworked Killers have their own, unique Terror Radius Music.
Older Killers, who have received a major rework, as well as all new Killers, have their own, unique Terror Radius Music, which makes them easily identifiable.
Chase Music
Killers do not hear their own Terror Radius music, instead they hear the general background music that plays on all Maps at all times until they enter a Chase with a Survivor.
As soon as a Killer initiates a Chase, they will hear the Chase Music, which is equal to Layer 4 of the Terror Radius.
Originally, when the Developers had first started to give Killers their unique soundtrack, it was intended that the Chase Music was a completely unique track, distinct from Layer 4 of the Terror Radius and only ever heard by the Killer.
However, for unknown reasons, after releasing two Killers with a distinct Chase Music, The Demogorgon 
and The Oni 
(see Trivia section), the Developers abandoned that practice, eventually removing the unique Chase Music from those two Killers as well.
Akin to the Terror Radius Music, older Killers use one of 3 available generic Chase Music themes, whereas newer and reworked Killers have their own, unique Chase Music.
Non-Terror-Radii
Some Killers have Terror-Radius-like mechanics that are, however, not considered to be true Terror Radii.
This includes mainly Lullabies and Fake Terror Radii.
Lullaby
Some Killers, in addition to their Terror Radius, feature what is referred to as a Lullaby.
With the exception of the name-giving Lullaby sung by The Huntress 
, as she was the introductory Killer of that mechanic, a Lullaby in Dead by Daylight merely refers to any Terror-Radius-like mechanic fulfilling the properties listed below, which are different from those of regular Terror Radii.
Other Killers with a Lullaby mechanic, generally refer to it under a different name:
Lullaby properties:
- Lullabies are non-directional.
- Lullabies have a fixed, unalterable range.
- Lullabies are not affected by Unlockables that influence the Terror Radius.
- Lullabies are not suppressed by the Undetectable
Status Effect.
Killers with a Lullaby:
- The Huntress : She hums a literal children's Lullaby, refers to the mechanic as a Lullaby.
- The Nightmare : Survivors hear a nursery rhyme when inside the Dream World, refers to the mechanic as a Lullaby.
- The Twins : Victor emits shrieks and groans when he is not with Charlotte, refers to the mechanic as Shrieks.
- The Trickster : He emits a modified version of the first layer of his Terror Radius, refers to the mechanic as a Melody.
- The Onryō : She emits a metallic screeching noise while Demanifested and inside the Otherworld, refers to the mechanic as a Lullaby.
Fake Terror Radius
Some Killers have the ability to alter their Power in a way that produces a Fake Terror Radius, which serves to confuse a Survivor.
Fake Terror Radius properties:
- Fake Terror Radii are auditorily indiscernible from a regular Terror Radius.
- Fake Terror Radii have a fixed, unalterable range.
- Fake Terror Radii are not affected by Unlockables that influence the Terror Radius.
- Fake Terror Radii do not interact with any Unlockables that require the presence of an actual Terror Radius to activate/charge.
- Perks like Diversion or Stake Out will not charge their Tokens while inside a Fake Terror Radius, which can be used to distinguish it from a real one.
- Perks like Starstruck will not trigger the Exposed Status Effect for Survivors inside a Fake Terror Radius.
- Perks like Diversion
Killers with a Fake Terror Radius:
- The Hag : the Terror Radius emitted by a Mud Phantasm is a Fake Terror Radius.
- The Doctor : the Illusionary Terror Radii inflicted by the "Calm" or "Discipline" Add-on Series is a Fake Terror Radius.
Undetectable Mechanic
There are several Unlockables, as well as Killer Powers, that can temporarily cloak a Killer's Terror Radius, all of which apply the Undetectable 
Status Effect.
- The Wraith cloaking himself and entering the Spirit World.
- The Hillbilly using the Leafy Mash or the Iridescent Brick .
- The Nurse using the "Bad Man's" Last Breath .
- The Shape while remaining in Evil Within I.
- The Hag using the Grandma's Heart .
- The Huntress using the Wooden Fox .
- The Pig crouching.
- The Ghost Face using Night Shroud.
- The Demogorgon after traversing the Upside Down.
- The Deathslinger using the Hellshire Iron .
- The Executioner using the Obsidian Goblet .
- The Blight using the Vigo's Journal .
- The Twins using the Silencing Cloth .
- The Nemesis using the Serotonin Injector .
- The Cenobite using the Chatterer's Tooth .
- The Artist using the Iridescent Feather .
- The Onryō while Demanifested.

Trivia
- Unlockables that affect a Terror Radius via a percentage tend to apply that on top of the base Terror Radius, ignoring other Unlockables that affect it by a concrete numerical value.
Old Terror Radii
