How Shirley Jackson turns an unseen knock into something with weight, distance and terrifying intention.
The Power of Sound in Writing
You do not simply read a great book. You hear it.
Reading may look like a silent activity, but the most convincing stories create an entire soundscape inside the imagination. A distant train, a humming refrigerator, a pencil snapping between someone’s fingers—each sound tells us something about the place, the people and the emotional temperature of the scene.
Sound can establish safety. It can quicken the pace. It can warn us of danger before we understand what that danger is.
It also has a peculiar power that visual description does not possess. We can close our eyes to something frightening, but an unexplained sound demands an answer. The mind immediately begins searching for its source.
What made that noise?
How close is it?
Is it moving?
And, perhaps most importantly, did it mean to be heard?
In this Stop Writing in Silence series, I examine how remarkable authors use sound to shape the reader’s physical and emotional experience—and what other writers can learn from them.
We begin with a house that does not merely contain frightening noises.
It appears to make them.
Shirley Jackson and The Haunting of Hill House
Published in 1959, Shirley Jackson’s The Haunting of Hill House follows four people who enter a supposedly haunted mansion to investigate its supernatural reputation.
Dr John Montague has assembled the group as a scientific experiment. Luke Sanderson represents the family that owns the property. Theodora possesses an unusual sensitivity, while Eleanor Vance arrives carrying years of isolation, resentment and frustrated longing.
The novel’s greatest question is not simply whether Hill House is haunted.
It is whether the house is acting upon Eleanor—or whether Eleanor’s troubled mind is transforming the house around her.
Jackson protects that uncertainty carefully. She rarely allows the supernatural to step completely into view. Instead, she lets the characters—and the reader—hear it.
Before the noises begin, however, she establishes something equally important: silence.
“Silence lay steadily against the wood and stone of Hill House.”
This is not peaceful silence. It lies against the building materials as though it has weight. It feels accumulated, deliberate and watchful.
Jackson prepares the stage by removing ordinary sound from it.
Then she knocks.
The Threat Outside the Door
One of the novel’s most frightening sequences traps Eleanor and Theodora inside a bedroom while something moves through the house.
They hear pounding and knocking. The disturbance travels through the corridor and reaches their door. The women cannot see what is causing it, but its repeated impacts make the barrier between them and the unseen presence feel dangerously thin.
Jackson could have shown us an apparition.
Instead, she gives us a door.
That door becomes the scene’s entire visual boundary. On one side are the women. On the other is something that may or may not exist.
By refusing to reveal the source, Jackson hands the work to the reader’s imagination. We picture the corridor. We anticipate the next impact. We wonder whether the hinges will hold.
The unseen presence can assume any shape because Jackson never confines it to one.
A visible monster has dimensions.
A noise in the darkness does not.
The Trick: Give Sound Physical Weight
Jackson does more than tell us that the characters hear a bang. She makes the sound interact with physical space.
It travels through halls. It strikes wood. It seems to test the strength of doors and walls. Its force can be judged by the house’s reaction to it.
That distinction matters.
Compare these two descriptions:
There was a loud bang outside.
The door jumped against its hinges.
The first identifies a noise. The second makes us feel its force.
The reader may not know what struck the door, but the movement provides evidence that something did. Sound becomes physical action.
This is one of Jackson’s most useful lessons for writers: describe what the noise does, not merely what it sounds like.
Does a glass tremble on the table?
Does conversation suddenly stop?
Does dust fall from the ceiling?
Does a sleeping dog raise its head?
A convincing sound leaves fingerprints upon its surroundings.
Repetition Creates Intention
A single unexplained noise might be dismissed.
Old houses contract. Pipes knock. Wind moves branches against windows.
But when a sound returns, the reader begins to detect a pattern. Pattern suggests purpose, and purpose suggests the presence of a mind.
Jackson uses repetition to move the characters through three stages of fear:
First, they hear something.
Then they wait for it to happen again.
Finally, they realise that it appears to be approaching them.
That middle stage—the waiting—is where much of the terror lives. Once the reader expects another impact, every quiet second becomes charged.
The silence is no longer empty.
It is a countdown.
This is why relentless noise can become less frightening if it continues without interruption. The reader grows accustomed to it.
Jackson allows the sound to stop.
The characters listen.
We listen with them.
Then it returns.
Silence Is Part of the Soundscape
Writers sometimes interpret sound as a requirement to fill a scene with noise. But silence is not the absence of sound writing. Used deliberately, it is one of its most powerful forms.
Silence controls anticipation.
After a knock, silence asks whether another will follow. After a scream, it makes us wonder why the screaming stopped. When the ordinary background sounds of a place disappear, silence tells us that something has changed.
Imagine a forest in which insects have been chirping throughout the scene. If they suddenly stop, the writer does not need to announce danger. The missing noise does it.
Jackson understands this instinctively. Hill House’s silence feels alert, as though the building is capable of listening. When the pounding begins, the silence has already taught us to fear whatever might disturb it.
Sound and silence are therefore not opposites.
They are partners.
Each gives the other meaning.
The Feeling: The Invisible Impact
Jackson’s technique produces what we might call the Invisible Impact: the sensation of experiencing the force of something that remains unseen.
The reader feels the assault through the characters’ bodies and through the room around them. We know the sound has power because the women recoil from it. We feel its size because it seems to occupy the corridor and shake the door.
Yet we never receive a reassuring explanation.
That uncertainty is essential. If Jackson identified exactly what was making the noise, the scene would become an encounter with a particular creature or phenomenon. Because she withholds that information, the sound remains connected to every possible fear.
It could be the house.
It could be a ghost.
It could be Eleanor’s mind.
Or it could be something the reader has imagined and cannot quite dismiss.
What Writers Can Learn from Shirley Jackson
When using sound, do not treat it as decoration. Let it change the scene.
A useful sound should affect at least one of three things:
The environment: Something shakes, falls, echoes or becomes still. The character: Someone freezes, mishears, remembers or anticipates. * The reader’s question: The noise introduces uncertainty about its source or meaning.
Also consider its progression. A frightening sound rarely needs to begin at maximum volume. Let it emerge, disappear and return. Allow the reader to notice its rhythm and imagine its approach.
Most importantly, resist explaining it too quickly.
The mind cannot tolerate an unexplained noise. It will try to give that noise a source, a shape and an intention. That imaginative participation is often more powerful than anything the writer could place visibly in the room.
Try It Yourself
Write a character alone in a familiar room.
Introduce a small, ordinary sound: a tap in the wall, a floorboard settling or the soft scrape of something outside the window.
Repeat it—but alter one detail. Move it closer. Change its rhythm. Make it answer something the character does.
Do not reveal the source.
Instead, describe the effect on the room and the character. Let a glass tremble. Let the character hold their breath. Let the silence after the sound last slightly too long.
Your objective is not to describe a frightening object.
It is to make the reader listen for one.
Shirley Jackson understood that the imagination does not need to see the monster to fear it.
Sometimes all it needs is a closed door—and one more knock from the other side.
