PROBLEM TO BE SOLVED: To provide a sound absorbing material for a compressor for an air conditioner capable of absorbing the generation sound of a compressor by covering the outer peripheral part of a compressor of a sound source and forming a plurality of Helmholtz resonators. SOLUTION: In a sound absorbing material 4 to cover the outer peripheral part of a compressor, forming a sound source, placed on the bottom plate of a easing through a plurality of leg bodies, the sound absorbing material 4 is formed of double structure to form a plurality of Helmholtz resonators 4b each consisting of a resonance case 6 formed such that the outside is opened and an air chamber 5 is formed at an internal part, an orifice hole 7 formed on the sound source side of the internal case 6, and a sound shielding cover 4a to cover the opening part of the internal part case 6. |
