Low and thick. It can express the charm of the bass without reservation. Do soundproof rooms for bass exist? The answer is, "They do." For those looking for a soundproof room that can truly resonate with the essence of the bass, we present this. The low frequencies of an electric bass can easily penetrate floors and walls, and when connected to an amplifier, it can produce sound levels of around 120 dB (just before a plane's propeller engine). Additionally, the vibrations from the amplifier transmit through the floor to the surrounding area, making soundproofing difficult. To effectively prevent this sound leakage, installing a soundproof room is indeed the most effective solution. In the case of a modular soundproof room, a space of about 1 to 1.5 tatami mats should be sufficient to enjoy bass playing. *For more detailed information, you can view it through the related links.

The exterior looks like a container for transporting goods, but inside, it is a soundproof room where a full band can perform. We would like to introduce a case study of such a construction project. The client is a big band enthusiast and a guitarist who enjoys jamming and recording with bandmates without worrying about time, creating a special space for themselves. We used a second-hand container. Given the site and transportation considerations, it was challenging to install a full 40-foot container, so we split it into two 20-foot sections for transport by truck. It was then assembled on-site with a large forklift, and welding was done at the site, followed by painting repairs on the welded sections. The container was painted in a specified color at a yard in Nagoya. Additionally, since the client wanted to enjoy movies and music on a large screen while creating a soundproof studio, we used wallpaper made of material that could serve as a screen for the walls. [Case Overview] - Sound sources: Full band, electronic drums, DTM - Room size: Studio 6 tatami mats, break room 7.2 tatami mats, total 13.2 tatami mats, 40-foot container - Construction duration: 35 days - Construction area: Aichi Prefecture *For more details, please download the PDF or feel free to contact us.

I would like to introduce a case of audio room construction carried out by the staff of the audio shop that I always rely on. The flow of sound and the treatment of standing waves, as well as the flat characteristics that are important for sound decomposition. Additionally, since low frequencies are the main cause of damage to the mid and high ranges, we utilized the know-how from the "Sound Quick Series" to smoothly adjust the acoustic panels on the walls, focusing on 125Hz, achieving clear low frequencies while maintaining clarity in the mid and high ranges. This has resulted in an audio room that specializes in both acoustics and soundproofing, bringing out the original performance of the audio and the brilliance of the mid and high ranges. 【Case Overview】 ■Sound Source: Audio ■Room Size: 8 tatami mats ■Construction Duration: 21 days ■Construction Area: Nagoya City *For more details, please download the PDF or feel free to contact us.

This is an introduction to a case study of a renovation project that involved transforming a condominium from a skeleton state, where we collaborated with a local design firm to confirm detailed specifications through meetings and drawings, while also conducting soundproofing work. The electrical and finishing work was carried out by the renovation contractor, and the soundproof door was specified in terms of paint color by the design firm, with a baked finish applied to a KOTOBUKI soundproof door. During the acoustic adjustment, the resonance of the customer's piano and the sound produced by the room created an indescribably pleasant atmosphere, making it a soundproof room where one would want to play continuously. The soundproof door achieved a sound insulation performance of 30dB in front of it with a piano and guitar (electric and acoustic), while the sound insulation performance beyond the soundproof wall was 45dB. [Case Overview] ■ Sound sources: Piano, electric guitar, acoustic guitar ■ Room size: 5.6 tatami mats ■ Construction duration: 20 days ■ Construction area: Saitama City *For more details, please download the PDF or feel free to contact us.

"Sound Quick" is an acoustic panel that absorbs low frequencies. It efficiently absorbs low frequencies through diamond-shaped openings using aluminum sintered plates, eliminating sound muddiness found in spacecraft, resulting in clear bass. When two panels are installed on the bottom, the center of gravity for the low frequencies is lowered, and when two panels are installed on the top, they balance the processing from low to mid and high frequencies. 【Features】 ■ Utilizes materials used in soundproof walls of Shinkansen trains and spacecraft ■ Produces an audio and musical quality ■ Allows for infinite sound creation ■ The sound changes based on the orientation and placement of the two diamond sections *For more details, please refer to the external link or feel free to contact us.

"Sound Quick" is an acoustic panel that uses aluminum sintered plates to efficiently absorb low frequencies through an opening shaped like a diamond. It eliminates sound muddiness, which is also used in spacecraft, allowing for clear low tones. To preserve the mid and high frequencies as much as possible, the area of the sound absorption adjustment section is not overly ambitious; however, the structure allows for maximum sound absorption in the low frequencies. As a result, edges in the low frequencies are created, and controlling the low frequencies brings out the mid and high frequency information clearly. 【Features】 ■ Utilizes materials used in soundproof walls of Shinkansen and spacecraft ■ Reproduces sound field space ■ Enables infinite sound creation *For more details, please download the PDF or feel free to contact us.
