Experimental study of sound wave propagation patterns

Abstract

The present study compares the behavior of different sound types and their sources concerning distance. Experimental findings demonstrate a consistent reduction in noise levels with increasing distance from the sound origin, aligning with anticipated sound propagation patterns. Median noise level reductions are quantified, showing decreases from 72.7 dB at the source to 54.8 dB at a distance. Pulsed sounds exhibit pronounced fluctuations and peaks at close distances, while steady and blended sounds maintain more uniform levels. An exponential model accurately characterizes the noise reduction phenomenon (R² = 0.8664), underscoring its relevance for noise management, urban planning, and acoustic engineering applications. These results offer valuable insights into sound propagation dynamics and provide a basis for developing effective noise control strategies and optimizing environmental acoustics.
