Evaluation of Noise Characteristics of Drainage and Water Supply Systems in Apartment Bathrooms

Abstract:

We have developed a low-noise drainage system, which was installed in bathrooms of apartment building units as well as in a mock-up test building, to evaluate the noise level in order to reduce the noise produced in the bathrooms of multiunit dwellings. The drainage system installed in the mock-up building consists of six types of detachable drains, and the level of noise produced during toilet use in the upper unit was measured in the lower unit. The measurement results showed that low-noise drainage 4 exhibited the L_eq (equivalent continuous sound level) at 34.7 dB(A). The noise measurement results of various types of low-noise drains installed in an apartment building showed that the L_eq during toilet use was 46.7 dB(A) on average, and the L_eq during sink use was 40.5 dB(A) on average.
