The core difference between sound absorption and sound insulation lies in that sound absorption optimizes the sound field environment, while sound insulation blocks the transmission of sound.
①Sound absorption principle and effect: The material reduces reflection by absorbing sound energy, making the sound softer and improving sound quality.
②Sound insulation principle and effect: The material reduces transmitted sound energy by blocking sound propagation, achieving noise insulation.
③Differences in purpose: Sound absorption focuses on optimizing the sound environment, while sound insulation focuses on sound barrier.
