Bangs, bangs, rattles... These are ordinary everyday sounds that we hear in our daily lives, but what if they were scary sounds, with no clear source and an unknown source of fear?
The term "inter-floor noise" is a Korean term that refers to the sounds of daily life (footsteps, voices, door opening and closing sounds, household appliances, etc.) that can be heard from the floors above and below in an apartment building.
The Korean horror film "Inter-Floor Noise," set in an old apartment complex where the noise of darkness reverberates, was released in Korea in June 2025. Immediately after its release, it went viral and became the most popular Korean film in three weeks.
It has been ranked number one for two consecutive years, making it the most successful horror film of the year to date (as of August 15th)! It was also the winner of the 57th Sitges Catalonia Film Festival, a world-renowned film festival specializing in genre films.
Artistic Director Angel Sala Corbi described it as "the best jump scare of the year," and others have praised it as "a return of 'Dark Water'" and "a new masterpiece of Korean horror."
The director, Kim Suzyn, is a talented director who has won the Best Film Award in the "40,000 Blows" category at the Mise-en-scène Short Film Festival, and is also the sound director for "The Wailing" and "Gonjiam."
The film's director, Park Yong-gi, creates a chilling soundtrack like never before. The hearing-impaired protagonist, Seo Ju-yeon, is played by Lee Sun-bi, who starred in the TV series "Potato Laboratory."
The role of the mysterious neighbor, who is also troubled by the noise in the apartment complex, is played by Ng.
The role is played by Ryu Gyeong Su, who has been gaining attention for her role in the hit TV series "Seoul Unknown" on Streaming. The story is about Seo Juyeon, who is deaf, who finds out that her younger sister, Juhee, suddenly passes away.
Juyeon is informed that she has disappeared. The two used to live together, but Juhee starts complaining that she hears noises. Juyeon says that she can't hear the noises even with her hearing aid, and that the disagreement led to a fight.
When I entered the apartment in the apartment complex where Juhi lived, the ceiling was completely covered with soundproofing sheets. A neighbor came to visit me and asked, "Can you please be quiet at night?
However, after Ju-hee disappeared, there was no one in the room... Ju-yeon decided to stay in the apartment complex until her sister was found, and through a hearing aid,
Then he begins to hear strange noises. Soon he begins to sense the presence of something, not just sounds... Could these be related to his sister's disappearance, or...?
The film features an old apartment complex with many residents, which is depicted as the stage for the tragedy.
We received many photos showing the disturbing items scattered around the room. The first thing that catches your eye is the notice posted on the entrance door of Room 604 where the main character, Seo Juyeon, lives.
The message reads, "Please be quiet," giving off a slightly ominous vibe. However, in another cut, a note was left with scribbled notes in red marker that read,
There are many threatening messages such as "I'll kill you! Groans! Sounds of chairs! Sounds of footsteps!". There is a clearly tense atmosphere, and you can sense something strange. It is also having a negative impact on the neighboring residents.
It can be said that this is evidence or an item that shows that a frightening sound that can cause such a disturbance is reverberating in the apartment complex. In the accompanying cut, it is believed that the resident of Room 504 is the one who created these posters.
The man's figure can be seen. The video also captures the creepy scene of him ringing the intercom in the middle of the night to visit Seo Juyeon in room 604, and the sight of him laughing inappropriately will send chills down your spine.
It is revealed in the teaser that he visits with a knife in hand, making him an extremely suspicious character, and it cannot be denied that he may be involved in Juhi's disappearance.
Furthermore, it can be seen that there is a huge mysterious space under the housing complex where foreign objects are left abandoned, and there are also scenes of traffic accidents drawn in children's illustration books.
The photo shows a creepy image of a person clinging to a wall while bleeding, and a woman in a red dress with blood stains on her leg.
Director Kim Suzyn, who worked on the "sound-based" apartment complex horror movie that was the biggest hit in Korea in 2025, said, "Apartment complexes are a Korean
It is a very familiar building in the country, so we struggled to find a way to utilize the familiar space. We needed a housing complex that was not too old or too clean, and had a reasonable size.
Scary sounds are the most important element in this film, and I constantly discussed with the sound director how to express the sounds in various scenes. I believe that "the absence of sound" is also a form of sound expression.
We had a lot of discussions about the timing of when to play the sound and when to keep it silent," he said, revealing the techniques he used to give the audience "shivers."
The main character, Seo Juyeon, who is hearing impaired, covers her ears to block out the scary sounds, and gestures for "quiet" by putting her index finger over her mouth.
It also suggests that there is something that the film wants to keep secret. We hope you will come to the cinema to witness the true nature of the "scary sound" and the terrifying outcome. Director: Kim Suzyn
