Study of the Sound Absorption Performance of Ethylene-Vinyl Acetate Foam Materials
Medžiagotyra, 2019 Ethylene-Vinyl Acetate (EVA) polymer foam was prepared using a mold for this investigation. The effect of the cell structure parameters and pore filling gas type on the sound absorption performance of the EVA foam materials were analyzed in terms of ...

The Absorption of Sound in Gases [PDF]
Science, 1935 Several investigators have shown recently that if the changes in the internal energy of a gas take place so slowly that they cannot follow the adiabatic changes which result when a sound wave passes through the gas, sound dispersion and anomalous absorption of observable magnitudes occur.

Absorption of Sound by a Strip of Absorptive Material in a Diffuse Sound Field
The Journal of the Acoustical Society of America, 1959 The random incidence sound absorption coefficient is calculated for a narrow strip of absorbing material set in an otherwise reflecting plane. The assumptions made are that the material is of the locally reacting type, with a real normal admittance. The effect of an imaginary component of admittance is discussed qualitatively.
