STUDY OF ALTERNATIVE FLOOR AND CEILING SOUND INSULATION MEASURES AIMED AT REDUCING NOISE FROM AIR BORNE SOUND AND LIGHT-WEIGHT IMPACT SOUND ON CONVENTIONAL WOODEN FLOORS

This study was aimed at improving the sound insulation performance of floors in conventional wooden construction houses using simple and low cost measures. The main conclusions were as follows: 1. Laying a carpet on the floor led to a marked decrease in the penetration of air borne sound from the room above, but had little insulating effect against noise from impacts on the floor above. 2. Placing glass wool into ceilings in the room below was effective in reducing the effects of both airborne noise in the upper room and noise from light weight impact sounds on the floor penetrating into the room below. 3. And it is found that easy sound insulation construction plan for use of various construction materials
