We are active in the automotive industry while also pursuing the development of building materials for comfortable living spaces. In fact, the soundproofing and noise reduction technologies used to create quiet environments in luxury cars can be applied to the construction industry. For example, the soundproofing and noise reduction technologies used to create a quiet space inside a vehicle can also be utilized in residential space creation. Fire-resistant and vibration-damping materials can be considered in the same way. Additionally, if you share your concerns with us, we can propose flexible solutions tailored to your needs. Each professional, including chemists who uniquely formulate materials and engineers with analytical measurement technologies, collaborates to swiftly resolve issues. Please feel free to contact us.

We will improve the sound insulation performance of living spaces using acoustic evaluation technology developed from automotive technology. We can conduct acoustic evaluations in actual buildings, including sound insulation measurements of walls compliant with JIS, impact sound measurements of floors, and recordings of living sounds and measurement sounds. ■ Flow from Inquiry to Result Report Inquiry and Meeting ↓ Measurement Application and Procedures ↓ Building Measurement/Analysis ↓ Result Reporting ■ Measurement Contents 1. Sound Insulation Measurement of Party Walls/Partition Walls Using a high-volume speaker and a sound level meter, we measure the sound pressure level difference (D grade) between two rooms in buildings such as apartment complexes. (Compliant with JIS A 1417:2000) A higher D grade means it is harder to hear conversations or television sounds from the neighboring room. 2. Floor Impact Sound Measurement Using a tapping machine or impact ball, we measure the floor impact sound insulation performance (LL grade/LH grade) of buildings such as apartment complexes. (Compliant with JIS A 1418 and JIS A 1419) A lower LL/LH grade means it is harder to hear sounds from the upper floor. 3. Measurement Procedure & Time (Estimated for 1 Location) Setup of acoustic equipment (30 minutes) ↓ Measurement (30 minutes/location) ↓ Dismantling (30 minutes) Please feel free to contact us for more details.
