The opening scene of the Korean horror film ”Inter-Floor Noise,” featuring terrifying sounds, lasts about three minutes and is revealed for the first time!

The Japanese release date for the Korean horror film "Inter-storey Noise" (read: Soukan Sou-on) has been set for Friday, October 10th, and it will be shown at Shinjuku Musashinokan, Human Trust Cinema Shibuya, and other cinemas nationwide.
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 the sun reverberates, was released in Korea in June 2025. It went viral immediately after its release, becoming 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 called it "the best jump scare of the year," and others have praised it, calling it "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 known for the sound effects of "The Wailing" and "Gonjiam."
Director Park Yong-gi has created a chilling soundtrack like no other before. The hearing-impaired protagonist Seo Ju-yeon is played by Lee Seong, who appeared in the TV series "Potato Laboratory."
Bin plays the difficult role of a man who, while searching for his missing sister, is confronted with the terror brought on by mysterious noises.
The role is played by Ryu Gyeong Su, who is currently gaining attention for her role in the hit TV series "Unknown Seoul" currently streaming on ix. The story is about Seo Juyeon, who is deaf, and her younger sister Juhee.
They were informed that she had suddenly disappeared. The two had previously lived together, but Ju-hee began to complain about hearing noises, which Ju-yeon could not hear even with her hearing aid, leading to a disagreement that 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 shortly after and said, "Please be quiet at night.
"If you make any more noise, I'll tear your mouth apart," he threatened. 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 she was wearing a hearing aid.
He begins to hear strange sounds through the phone. Soon, he begins to sense not only sounds, but also the presence of something... Could these be related to his sister's disappearance, or...?
The opening scene of the film, which lasts about three minutes, is available, allowing you to experience the beginning of the horror.
From the beginning of the film, a strange sound like "biri-biri" or tearing of paper can be heard, destroying the atmosphere.
The woman's face is shown in close-up, and she can be seen fiddling with the ceiling and breathing heavily. It seems she is putting up a soundproof sheet on the ceiling, which is a strange sight.
After putting on the sheet, the woman presses the record button on the video camera and starts filming the inside of the room, but the moment the glass window is filmed, a mysterious "grrr" sound is heard.
A "scary sound" rang out. Then the intercom for "Fur Elise" rang and a woman picked up the receiver, but a noise like a child crying was heard. She slowly put the receiver down.
As he looked around, he noticed something strange happening on the TV screen, which was distorted and showing static. He turned off the TV with trepidation, and although there was a brief power outage, it was restored immediately, and he looked a little relieved.
While standing there, I quietly looked towards the window... The video faded out as the volume of the horrifying sound effects grew louder. The woman who appeared was named Juhi, and after this incident,
What on earth happened to her? And what is the meaning of the soundproof sheet on the ceiling? Joo-hee's older sister, Seo Ji-hee, who is hearing impaired, investigates the mysterious disappearance.
The story unfolds as Yooyoung searches for clues, and you'll witness an important scene that marks the beginning of the horror film that will send chills through Korea in 2025.
Director Kim Suzyn, who directed this "sound-based" apartment horror film about the realistic noise problem in an apartment, answers questions about what inspired her to make this film.
"I thought that the unknown sound coming from somewhere would be an important medium that connects the two, the fear of the supernatural and the fear of human harm. Since noise has become a social problem,
While writing this, I saw many incidents on the news. The most interesting stories were those that occurred in apartment complexes with terrible noise problems. Like many Koreans, I have lived in apartments since I was a child.
Because it was a place like that, it reflected a lot of personal experiences. In apartments and housing complexes, anonymity is very high. Even though many people live in close proximity, they are not aware of each other.
I don't know much about them. Even if I don't know where they live, someone might know me. I felt that this creates a lot of tension.
"I tried to incorporate that feeling into the whole film, for example, the anonymous note with an unknown sender that appears in the film," he said, revealing that he got inspiration from everyday life, and made this film.
This chilling film has been recognized as the most popular horror movie in Korea in 2025. Be sure to check out the movie theater to experience the "scary sounds" that are said to have occurred on set.
But I want you to relive it! Director: Kim Suzyn Cast: Lee SunBin, Kim MinSeok, Han SooAh, Ryu Gyeong Su, Jeong Ik-ryong and others
