This study explains why low-frequency sound is perceived differently at varying listening distances. By analyzing sound pressure decay, spatial energy distribution, environmental reinforcement, and perceptual sensitivity, it shows that changes in bass perception are primarily caused by acoustic behavior rather than loudspeaker performance.

This study examines why low-frequency sound is commonly perceived as stronger in indoor environments than in outdoor settings. By analyzing boundary reflections, air volume limitations, energy retention, and resonance effects, it shows that differences in bass perception arise primarily from environmental conditions rather than changes in loudspeaker performance.

This study compares how low-frequency sound propagates in indoor and outdoor environments. By examining boundary reflections, air volume limitations, and spatial openness, it explains why bass behavior differs significantly between enclosed rooms and open-air settings, independent of loudspeaker system configuration.

This study examines how environmental conditions influence the propagation of low-frequency sound. By analyzing boundary configuration, air volume, surface material properties, and indoor versus outdoor environments, it explains why perceived bass behavior often depends more on surroundings than on loudspeaker design itself.
