The True Meaning of Soundproofing Levels and Noise Reduction Guarantees
The Comprehensive Overview of Enclosure’s Soundproofing, Noise Reduction, and Absorption Guarantees
Enclosure provides guarantees for soundproofing performance, noise reduction, and sound absorption, offering various benefits. Unlike subjective measures, our solutions are backed by measurable data, ensuring theoretical validation. Additionally, these guarantees enhance reliability as external references, and in the rare case the set values are not achieved, we provide manufacturer-covered corrections. This initiative contributes to establishing unified standards across the industry.
1. Soundproofing Performance Guarantee
Enclosure establishes guaranteed values for transmission loss (soundproofing performance) and measures the actual performance of installations using specialized measuring equipment. After meeting the guaranteed values, we provide a Soundproofing Measurement Test Result Report to the customer. Measurements are conducted based on our in-house standard 1-1 or in compliance with JIS standards.
2. Noise Reduction Guarantee
We guarantee how much noise reduction will be achieved after installing soundproofing equipment. By measuring noise levels at multiple points before and after installation, we verify the change in noise levels and submit a detailed report.
3. Sound Absorption Guarantee
We provide a guarantee for the range of compliance with the inverse square law in anechoic chambers. This is evaluated using ISO-3745 standard measurements to ensure precise sound absorption performance. By utilizing directional speakers and sound level meters, we validate the guaranteed values and permissible ranges, then submit a Measurement Result Report.
Our Commitment to the Guarantee System
Since its inception, Enclosure has implemented this performance guarantee system, pioneering its adoption within the acoustic industry. Previously, very few manufacturers offered performance guarantees. By attaching guarantees to all products, we have raised industry standards in collaboration with users and distributors.
Although performance guarantees are now considered standard in the industry, the reality is that some manufacturers do not even conduct noise measurements. Moving forward, Enclosure aims to expand performance guarantees into the architectural acoustics sector, where they are not yet widely implemented, in addition to industrial noise control.
Detailed Reporting with Every Guarantee
Enclosure submits detailed reports based on our guarantee system. The reports include:
- Noise data (frequency analysis) of the installation site
- Guaranteed soundproofing values and predicted values
- Guaranteed and predicted noise levels post-installation
- Post-installation soundproofing measurement test results and measurement methods
- Guaranteed range of compliance with the inverse square law and its corresponding report
