dc.description.abstract | 早期音樂產業還處於類比製作時,錄音器材和混音相關的專業設備機組複雜巨大難以攜帶,而且價格高昂遙不可及。隨著數位音樂科技的普及化,製作專業等級的音樂門檻降低,許多專業音樂人開始打造自己的居家錄音室,即使是業餘音響玩家也能透過調音器材的購買和施作,創造出劇院級的美妙聲場。然而選擇自己家中的房間改造成錄音室,室形通常都會有些許聲場上的缺陷,一般房屋牆壁、天花板與地板的建材多為不利於聲音擴散與吸收的材質。
本論文的個案,運用RC建築的一間空房間,在它最原始的狀態時,應用木質材料使其發揮吸音、擴散以及低頻陷阱的功能來調音;先透過賽賓公式與電腦軟體EASE的模擬取得房間室形與原始建材形成初步聲場的各聲學指標數值,以在模擬狀況中使用各類木質材料調音;而後實際採用其材料來改善空間中的聲場。工程完成後進行監測調音效果,比對實際改善後聲場與原始音場和模擬聲場之各聲學指標結果是否符合;再分析房間是否因木質調音材質和收音位置對聲學指標造成顯著影響,其中包含背景噪聲、迴響時間與聲壓分佈。 研究結論顯示迴響時間與總聲能聲壓位準在聲學模擬軟體模擬之結果與實測狀況符合,能夠由模擬軟體模擬木質調音材料放置的面積與位置達到預想的效果。利用木質材料改善室內空間聲場對於迴響時間與總聲能聲壓位準有顯著影響,對背景噪音之影響不顯著。收音位置的改變則對總聲能聲壓位準有顯著影響,對迴響時間與背景噪音影響不顯著。 | zh_TW |
dc.description.abstract | At the analog age in the past music industry, the high price and huge volume the of recording, audio mixing devices and other professional audio equipment make the barriers to entry. The digital music technology nowadays has broken the barriers. Many musicians can build a home recording studio without difficulty, and amateurs can create acoustic fields just like the performance in the theater with tuner. However, the acoustic performance in reforming a home interior into a recording studio will be limited by the original room mode, and the materials of the wall, ceiling and floor in normal are not designed for high acoustic reflection and absorption performance.
This paper demonstrates the case of reforming a home interior into a recording studio in RC building. First, apply the Sabine’s formula and the EASE software for acoustic simulation to get the target value of the acoustics in the original state. Then test the wood-based tuning materials to determine the acoustical absorption, reflection and bass traps in order to tuning in the simulating state, and use the material suggested in the simulating state to create a better acoustic field in reforming. Finally, compare the acoustic performance before and after reforming to see if it is accord with the target value. Analyze background noise, reverberation time and sound pressure distribution of the reforming space to see if the wood-base tuning materials and the reception position contribute to the problem of failing to meet the target value. Results show that the reverberation time, total sound power level and pressure level in measurement meet the outcome of EASE simulation software, the measurement works as expected from simulating the area and the position of the wood-based tuning materials. The wood-based material to interior acoustic field has significant influence on the reverberation time and total sound pressure level, but less on the background noise. The reception position has significant influence on total sound pressure leve, but less on reverberation time and background noise. | en |
