The Core of Architectural Acoustics Revealed by Psychoacoustics

This channel provides information to those interested in architectural acoustics, electroacoustics, psychoacoustics, and 3D audio. This material focuses on a *master's thesis* that analyzes how humans perceive the *reverberation characteristics* of indoor spaces from a *psychoacoustic perspective**. The study conducted listening experiments by establishing three key parameters: **Initial Time Delay (ITDG)**, **Reverberation Time (RT)**, and **Initial Reflection Density**. The **Adaptive Stepping Method* and *Forced Selection Method* were applied to the experiment, and *Difference in Minimum Value (JND)* was measured using various sound sources, including instruments and voices. The analysis revealed that while changes in *Reverberation Time* are perceived relatively clearly, *ITDG* has a relatively low cognitive correlation. This research contributes to clarifying the *relationship between subjective evaluations and objective indicators* to improve the accuracy of *concert hall design* and acoustic modeling.
