Sound barriers are designed to reduce and eliminate noise and echoes generated by roads, butthey can also cause many problems for high-rise buildings .That is, when the sound receiving pointis higher than the position of the silencing source, the noise will directly cross the sound barrierand generate noise, which will cause problems . Soundproof tunnels are vertical sound barriers.used as a representative method to eliminate noise from high-rise and ground level buildings.

When the water in the sink reaches a certain level. the sink wilautomatically open the partition below, and the rainwater will flow away while cleaning the interior andsides of the sound barrier.
