一、航空及陸運 航空噪音方面已完成建議及修訂航空噪音相關法規及更新指引，建立查核SOP協助完成3處機場共計9站次之監測站查核，俾提昇監測能力以確保航空噪音監測之品質及正確性，並完成檢討航空噪音監測站之設置位置及數量（包含「應設置自動監測設備連續監測機場周圍地區飛航噪音狀況之航空站」之17座航空站）及航空站自動監測設備，以提高噪音監測資料可用率。，維護更新「航空噪音監測資料判讀工具2.0版」以減少人為誤判，避免過往於航空噪音查核之缺失一再產生。 陸運噪音方面已完成建議及修訂相關法規及更新指引，並完成高速公路音源分離之技術面模擬建議以供實務上之參考，建議現場執行「音源端至受體端之多點位」量測，俾能正確建立音場模型分離出各音源之噪音貢獻。亦完成蒐集及分析日本最新道路用（邊緣效應抑制理論）及高鐵用（吸音、隔音和反射）新型隔音牆，均已有朝向簡化、不額外加裝繞射和干涉裝置之趨勢。 二、聲音照相 已完成「聲音照相科技執法1.0」搭配麥克風陣列」之「多車源機動車輛噪音照相系統（即聲音照相科技執法2.0）」及現場測試（移動式15點次及固定式15點次），初步已可排除多車噪音干擾（含對向車道）。亦配合環保署完成1場次「多車源機動車輛噪音照相系統」諮詢會議，與各界進行技術交流分享，應用科技強化稽查以篩出高噪音車輛，協助多車源辨識，以提高執法效率。 三、空噪盒及營建噪音 針對空氣噪音整合監測已完成Class 2麥克風（MEMS）整併既有空氣感測器（介面均採RS-485），並完成1處空氣噪音整合監測評估點，初步監測結果與Class 1麥克風結果呈現高度相關性。 營建噪音方面已完成「營建工程科技執法」規劃書及主要設備建置，藉由聲音校正器、Class 1噪音計、陣列式聲音感應器、風速計及搭配縮時攝影機，以不同樣態開發規格完成5場次營建工程實機測試。初步測試結果可達音源分離及辨識之效，判定主、次要噪音源以確認最大音量之噪音來源及位置，解決過往稽查時噪音消滅之情事，做為責任歸屬依據，亦建議下年度針對使用於機動車輛或營建工程之陣列設備功效及辨識能力進行驗證，草擬完整驗證程序及驗收標準，俾完備聲音照相科技執法工作。

一、 Air and ground transportation In terms of aircraft noise, completed suggestion and revision of related regulations on aircraft noise, guideline update, and inspection SOP. Assisted in completion of inspection on 9 noise monitoring stations at 3 airports for the purpose of enhancing monitoring ability to ensure the quality and accuracy of aircraft noise monitoring. Completed reviewing the set-location and number of aircraft noise monitoring stations (including the 17 airports that are under the regulation of the “Airports That Should Setup Automatic Monitoring Equipment and Conduct Continuous Monitoring of Aircraft Noise Situation in the Vicinity of the Airport”) and the automatic monitoring equipment at the airport in order to enhance the availability of noise monitoring data. Maintained and updated the “Aircraft Noise Monitoring Data Interpretation Tools 2.0” in order to decrease human error and avoid recuring of previous faults in aircraft noise inspection. In terms of ground transportation noise, completed suggestion and revision of related regulations and guideline update. Completed recommendations on simulation of audio source separation technologies on the highway to serve as reference for practice. Proposed that on-site measurement of “multipoint locations from source end to receptor end” be conducted in order to correctly create a sound field model to identify the contribution of each audio source to the noise. Completed collection and analysis of information on the new-type acoustic barriers most recently used on roads (fringe effect containment theory) and highspeed rail (sound absorption, acoustic insulation, and sound reflection) in Japan. The results show a trend of simplicity without having to add extra diffraction and interference devices. 二、 Acoustic camera Completed combined tests for microphone array with “Acoustic Camera Technology Law Enforcement 1.0” and “Multi-vehicle Source Motor Vehicle Acoustic Camera System” (Acoustic Camera Technology Law Enforcement 2.0), and on-site verification tests (15 mobile point tests and 15 fixed point tests respectively). The results show that, multi-vehicle noise interference (including opposite lanes) can be preliminarily excluded. In cooperation with the Environmental Protection Administration (EVA), conducted one consulting meeting on “Multi-vehicle Source Motor Vehicle Acoustic Camera System” to share and exchange information on related technologies with all walks of life. Advanced technology was used to strengthen inspections to screen out high-noise vehicles and identify multiple vehicle sources, so as to enhance law enforcement efficiency. 三、 Airborne noise and construction noise In terms of airborne noise integrated monitoring, completed combining Class 2 microphone (MEMS) into the existing air quality sensor (RS-485 was used as interface). Completed one evaluation point for airborne noise integrated monitoring. Preliminary monitoring results show high correlation with Class 1 microphone results. In terms of construction noise, completed Proposal for “Technology Law Enforcement on Construction Projects” and main equipment setup. By means of acoustic calibrator, Class 1 audio-noise meter, array sound sensor, anemometer, and time lapse camera, five real-machine tests on construction projects were conducted in different forms and development specifications. Judging from the fact that preliminary test results can achieve the effect of audio source separation and recognition, primary and secondary noise sources can be recognized respectively and so the maximum volume of the noise source and its location confirmed. Solved the problems of noise abatement in previous inspections to serve as basis for attribution of responsibility. Proposed that the effect and recognizing ability of the array equipment for motor vehicles or construction projects be verified and complete verification process and acceptance criteria drafted in the next year in order to perfect the law enforcement with acoustic camera technologies.
