Pixie Dust Technologies, Inc. (Headquarters: Chuo-ku, Tokyo, Representative Director and Chairman: Yoichi Ochiai, Representative Director and President: Taiichiro Murakami, hereafter PxDT), in collaboration with AlphaDrive Co., Ltd. (Headquarters: Nagatacho, Chiyoda-ku, Representative Director, President and CEO: Yoichi Aso, hereafter AD) and Taiga Global Inc. (Headquarters: Gwacheon-si, Gyeonggi-do, South Korea, hereafter TG), has begun joint product development of a new indoor greening solution with sound absorption functions specialized for conversation frequency bands. This solution equips TG's moss-based spatial greening solution with PxDT's embedded sound-absorbing module 'iwasemi OC-β'.
This initiative implements the 'subtraction of sound' design philosophy cultivated by PxDT through acoustic metamaterial technology into spatial greening. By combining iwasemi OC-β with TG's low-maintenance natural greening solution, the companies aim to develop a next-generation spatial solution that simultaneously achieves 'auditory comfort' in addition to the 'visual relaxation' of conventional greening spaces. AD will be responsible for demonstration, business development, and sales in the Japanese market.
### Eliminating Office 'Sound Stress' and the 'Barrier to Greening' Simultaneously Through Sound Absorption x Spatial Greening
In recent years, interest in creating spaces with well-being in mind has been growing in various spaces such as offices, commercial facilities, and public facilities. On the other hand, two challenges still remain in offices and public spaces. One is the challenge of the sound environment, such as decreased concentration and securing privacy due to conversation echoes and surrounding noise. The other is the challenge that even if people want natural greening, indoor greening is difficult to advance due to reasons such as maintenance costs and load-bearing capacity.
By combining PxDT's embedded sound-absorbing module 'iwasemi OC-β' and the low-maintenance natural greening solution provided by TG, the three companies aim to provide an unprecedented spatial experience where 'green relaxation' and 'subtraction of sound' resonate.
### Roles of the Three Companies: PxDT Handles Acoustic Technology, TG Handles Greening Technology, and AD Handles Business Development
In this joint development, PxDT is responsible for providing the technology and product design for the sound-absorbing module 'iwasemi OC-β', which utilizes the acoustic metamaterial technology 'iwasemi'. TG is responsible for developing and providing technology for the spatial greening solution using moss. AD is responsible for demonstrations, business development, and product sales with an eye toward expansion into the Japanese market, and will proceed with the implementation of the solution in a form suitable for Japanese office environments and spatial needs.
### About the Embedded Sound-Absorbing Module 'iwasemi OC-β'
iwasemi OC-β is a sound-absorbing module that applies acoustic metamaterial technology to suppress sound reverberation by focusing on the core frequency band of human conversational sound (500 to 1000 Hz). By enhancing not only sound-absorbing performance but also the degree of freedom in design, materials, and construction, it shifts the positioning of sound absorption from a 'stick-on' countermeasure to an 'embedded' design.
