Hearing design for soundproofing and sound insulation | Kamiyama Choukei Office
Why is the sound carelessly treated when the interior is particular?

Sound is the architecture of the heart
Creating spaces with consideration for soundscapes—a practice rooted in human history since ancient times.
By continuously embracing the “quiet joy” of sound environments, we craft spatial experiences that linger in the heart.
Drawing on expertise cultivated through environmental music and immersive soundscape experiences, we express memorable spatial moments under the banner of Chokei Design.

Points Of Chokei Design
Chokei Design is a sound design service that harmonizes with the environment.
We analyze spatial elements such as services, functions, and target demographics, and craft tailored environmental sounds to create high-quality spatial experiences.
Rather than merely serving as an acoustic solution, our approach enriches comfort through sound itself—infusing artistic sensibility to bring richness to the space through the ear.

Voices from Our Clients
Yuuki Nakajima
Business Development Department, East Japan Railway Company (JR East)
Support provided: Acoustic enhancement for STATION DESK Tokyo Marunouchi
STATION DESK Tokyo Marunouchi is a 50m² co-working space featuring 16 seats, including semi-private booths and phone booths.
To help users relax and focus amid the hustle and bustle of the station, we paid close attention to the details of the spatial design—seats where you can take off your shoes and lie down to work, calming aromas, and lighting with just the right level of brightness.
However, when it came to sound, we had simply followed the common approach seen in many shared offices: playing commercially available background music.
I still vividly remember the impact of switching from standard BGM to the environmental music created by Chokei Design.
Standing at the edge of the space, it was as if the entire view had transformed.
The response from users has also been overwhelmingly positive.
Heavy users were quick to notice the change—many have commented that their work productivity has improved, and others have shared how the music itself feels more stylish and sophisticated.
