Attenuation of sound radiation in concrete structure through the reduction of mechanical vibration
Revista IBRACON de Estruturas e Materiais, 2018 The efficiency of sound irradiance in structure has direct relation with its vibratory movement. Dynamic vibration absorbers (DVAs) are a low cost viable option for reducing vibrations in passive structures.
