Discover how different lighting concepts influence visual performance, perceived spatial quality, emotional response, and employee well-being, providing valuable insights for human-centered workplace design.

Effective sound insulation is essential for creating comfortable and productive indoor environments, yet controlling low-frequency noise remains one of the greatest challenges in building acoustics. This research investigates how periodically arranged viscoelastic materials can improve the transmission loss of sound insulation panels without relying solely on heavier construction.

Through experimental laboratory testing, the study compares several viscoelastic configurations and demonstrates significant improvements in low-frequency acoustic performance. The findings provide practical insights for architects, acoustic consultants, façade engineers, and building designers seeking more efficient sound insulation solutions for modern buildings.

Presented at the Regional Conference on Acoustics and Vibration (RECAV) 2017, this research examines the influence of splayed wall geometry on acoustic mode distribution in small rooms using Finite Element Method (FEM) simulation.

The study addresses one of the most common challenges in architectural acoustics—room modes caused by parallel surfaces—which can degrade sound quality and spatial uniformity.

The findings demonstrate how thoughtful room geometry can become an effective passive acoustic design strategy, offering practical insights for architects, engineers, and acoustic consultants involved in designing high-performance listening environments.
