在當今多媒體技術中，沉浸式聲響成為重要趨勢，尤其在電影、遊戲和虛擬實境（VR）應用中。聲音技術從傳統立體聲和環繞聲，進一步演進至沉浸式聲響，旨在提供更強烈的臨場感和沉浸感。

本研究探討雙耳聲響技術結合頭部追蹤技術在VR視聽作品中的應用，並比較Ambisonics和雙聲道Stereo Sound兩種聲響效果對觀眾沉浸體驗的影響，兩者均透過雙耳聲響技術呈現。實驗設計包括實驗組和對照組，觀賞後填寫問卷並評估五種沉浸感問項。結果顯示，Ambisonics聲響效果能顯著提升觀眾的沉浸體驗。相比雙聲道音效，Ambisonics提供更準確的聲音定位，讓聽眾在虛擬環境中有如臨其境的感受。然而，若沒有透過雙耳聲響技術呈現Ambisonics聲響，就必須架設高成本和複雜的喇叭設置才能聆聽。

創作《太陽系之旅》時，研究者使用了多種音樂創作軟體和工具，包括Cubase與多種效果器、虛擬樂器，製作沉浸式音樂和音效。研究探討了多聲道創作過程和VR視聽體驗的未來展望，認為隨技術進步和市場需求增長，沉浸式聲響技術將應用於更多領域，如影視娛樂和教育培訓等。未來研究可集中於降低成本和簡化設置，使更多用戶享受高品質沉浸式聲音體驗。

總結而言，本研究證明了雙耳聲響技術和頭部追蹤技術能有效提升VR視聽作品的沉浸體驗。隨著技術進步，這些技術有望在更廣泛應用中發揮重要作用，提供更真實和沉浸的體驗。研究者提出了一些改進建議和未來研究方向，以推動沉浸式聲響技術的進一步發展。

In contemporary multimedia technology, immersive sound has become a major trend, especially in films, games, and virtual reality (VR) applications. Sound technology has evolved from traditional stereo and surround sound to immersive sound, aiming to deliver a stronger sense of presence and immersion.

This study examines the use of Binaural Audio System combined with head-tracking technology in VR audiovisual works and compares the effects of Ambisonics and stereo sound on the audience's immersive experience, both presented through Binaural Audio System. The experimental design includes an experimental group and a control group, each consisting of 15 participants. After viewing the content, participants completed questionnaires to evaluate their sense of presence, sound immersion, emotional response, and overall sound evaluation. The results indicate that Ambisonics significantly enhances the audience's immersive experience. Compared to traditional stereo sound, Ambisonics provides more precise sound localization, making listeners feel as if they are truly in the virtual environment. However, if Ambisonics is presented through a spherical multi-channel system, its high cost and complex setup limit its widespread use.

In creating the work "Journey to Solar System," the researcher employed various music creation software and tools, including Cubase and a range of effectors and virtual instruments, to produce immersive music and sound effects. The study explores the multi-channel creation process and the future outlook for VR audiovisual experiences. The author believed that with technological advancements and increasing market demand, immersive sound technology will be applied in more fields, such as film and television entertainment, tourism, and education. Future research should focus on reducing costs and simplifying setups, enabling more users to enjoy high-quality immersive sound experiences.

In conclusion, this study shows that Binaural Audio System and head-tracking technology effectively enhance the immersive experience of VR audiovisual works. As technology continues to advance, these technologies are expected to play a crucial role in broader applications, providing users with more realistic and immersive experiences. The researcher also offer suggestions for improvements and future research directions to further develop immersive sound technology.
