2 results about "Urban noise" patented technology

This invention belongs to the field of urban noise management technology and provides a remote square dance sound noise control system, comprising: one or more speakers, each with an embedded volume control module, the speakers being distributed across one or more monitoring areas; a remote control terminal, which determines the noise threshold of the monitoring area and sends the noise threshold to the embedded volume control modules of the speakers within the monitoring area; after receiving the noise threshold, the embedded volume control modules within the monitoring area detect the noise volume inside the speakers, and when the noise volume inside the speakers is greater than or equal to the noise threshold, it shuts off the power supply circuit of the speaker motherboard of the speaker containing the embedded volume control module; this invention enables noise location and control to be specific to the speakers, achieving precise noise control and fairness. Simultaneously, the remote control terminal can set different noise thresholds for different monitoring areas, meeting the needs of regionally differentiated noise control.

This utility model discloses an environmentally friendly soundproof barrier to alleviate urban noise pollution, including a soundproof barrier with a light-transmitting component inside. The light-transmitting component includes a rotating frame with a transparent plate inside. One side of the rotating frame is rotatably installed inside the soundproof barrier. When the rotating frame needs to be rotated, two limiting blocks are pulled from the outside, i.e., the connecting rope and the locking block are pulled, causing the locking block to disassemble in the locking slot. When the inside of the transparent plate needs to be cleaned, the rotating frame is rotated outwards, moving the inner part of the transparent plate to the outside of the road for cleaning without obstructing the lane. When the rotating frame is rotated 90° outwards, the top of the bolt aligns with the limiting port. By rotating the bolt and inserting it into the limiting port, the rotating frame is fixed, facilitating cleaning of the transparent plate.
