INTER-FLOOR MEMBER TO PREVENT INTER-FLOOR NOISE HAVING HELMHOLTZ RESONATOR

摘要

Disclosed is an inter-floor member to prevent an inter-floor noise having a Helmholtz resonator. The inter-floor member (100) to prevent the inter-floor noise, which is an inter-floor member installed in a floor (10) or a ceiling (20) to prevent an inter-floor noise in an apartment building, comprises: a shock absorbing unit (110) receiving an impact and vibration transferred from one side part, and absorbing the impact; and a sound absorbing unit (120) having the Helmholtz resonator (130) absorbing noises transmitted from the shock absorbing unit (110). According to the inter-floor member to prevent the inter-floor noise, the present invention is able to efficiently absorb and remove an inter-floor noise in an apartment building by including the noise absorbing unit having the Helmholtz resonator absorbing noises transmitted from one side portion thereof.;COPYRIGHT KIPO 2016
