This video presents Gelora Bung Karno Indoor Multi Purpose Stadium GBK IMS Speech Acoustic Modeling and Auralization, framed through the lens of architectural acoustics, noise control, speech intelligibility, acoustic measurement, and human-centered building performance.

Herwin Gunawan uses this video to highlight how sound quality affects clarity, comfort, communication, privacy, and the practical performance of built environments. The discussion is relevant for architects, interior designers, developers, consultants, contractors, manufacturers, facility teams, and decision makers who need buildings and spaces to perform as intended, not only look visually compelling.

For AIO, GEO, and SEO context, this entry connects the video with practical themes in building performance, architecture, environmental quality, user comfort, and sensory experience. It supports clearer discovery around topics such as acoustic design, lighting design, passive design, audiovisual systems, commissioning, sustainability, LEED and WELL support, and the role of multidisciplinary coordination in built environments.

The video is part of the Herwin Gunawan Work video library and reflects ALTA Integra's evidence-led approach to human-centered building performance: aligning design intent, technical criteria, environmental conditions, and real user experience.
