This project assists the Ministry of Environment in conducting control-related actions on vehicle noise in use, construction site noise, vibration and low frequency, and analyzing each noise situation. By monthly compiling the
Environmental Protection Bureau's reports on the noise control effectiveness of various vehicles in use, it helps the Ministry of Environment understand the current implementation status and amend the guidelines to improve the effectiveness of vehicle noise control work. Referring to the application methods of literature, this year, three construction sites were selected for micro-sensor testing, measurements were carried out at the receptor end, and equipped with an over-standard warning function. Because of its lower cost and less power consumption. In the future, when conducting long-term and multi-point 2 construction noise monitoring, the use of micro-sensors will be an effective method and can be used as a follow-up to promote noise autonomy at construction sites. New ways of management. Assisted the Ministry of Environment in analyzing public complaints about noise and vibration in the past five years, and analyzed that most common low-frequency noise sources are caused by fixed facilities such as cooling water towers and motors, as well as karaoke speakers provided in business premises. After measuring vibration in 20 cases this year, the recommended values for factory vibration are 65 dB during
the day and 62 dB at night in the first and second controlled areas; 70 dB during the day in the third and fourth controlled areas. , 67 dB at night. This year, the "112-year National Noise Control and Light Pollution Related Exchange and Review Meeting" was specially held. The Environmental Protection Bureau and the organizing units were invited to participate, to communicate and discuss various noise control services with counties and cities, and to improve county and city implementation through experience sharing. efficiency and propose solutions to local difficulties so that various businesses can be executed smoothly.
