basic information
The "Fuji ZET" soundproof cover significantly reduces the noise from the compressed air emitted from the exhaust of concrete breakers. We commissioned the Japan Building Disaster Prevention Association to conduct noise measurements. The noise level of the concrete breaker was 97.7 dB, but with the soundproof cover "Fuji ZET," the noise level dropped to 87.4 dB, demonstrating a remarkable noise reduction effect of 10.3 dB. Additionally, as shown in the right diagram, the sound insulation effect is evident across the entire frequency range from 16 Hz to 8 kHz, indicating that it is effective in both low and high frequencies. ≪The values achieved without reducing impact force are due to the innovative patented structure.≫

Applications/Examples of results
An experienced expert with 50 years of experience in breaker cutting, who is well-versed in the subject, was not satisfied with the soundproof covers currently available on the market and dedicated himself to creating a truly usable soundproof cover for the field. This resulted in the completion of a soundproof cover that addresses three key improvements he had experienced and felt dissatisfied with in the past: enhancing soundproofing without reducing impact force, allowing for safe and secure work with a compact design, and considering durability and cost-effectiveness. With a commitment to this ambitious product development, and with the cooperation of various organizations and research institutes for basic structure and material development, he successfully cleared the development guidelines through trial and error, resulting in the "Fuji ZET." It is being evaluated and supported in the market as the next-generation soundproof cover, ideal for horizontal cutting.
