声学遗产是考古声学的一个方面,更具体地说,是指我们的建筑和考古历史中的建筑物、遗址和景观的可量化的声学特性,构成了我们非物质文化遗产的一个重要方面。听觉,相当于3D可视化的音频,使这些声学特性,通过测量和调查的过程中捕获,或基于计算机的建模,形成音频重建和研究空间的呈现的基础。本文探讨了听觉化和音频创意的应用,作为一种手段,探索我们的声学遗产,从而多样化和增强可用于数字遗产或人文研究的工具集。开放式声学脉冲响应(OpenAIR)库是一个声学脉冲响应和可听化数据的在线存储库,其中很大一部分是从广泛的遗产地收集的。用于收集这种声学数据的方法进行了讨论,连同在生成和校准一个可比的计算机模型,以及如何生成的数据可能会被分析和提出的过程。在音乐制作、混合媒体艺术作品和游戏音频的背景下,也考虑了这种声学数据的创造性使用。更具体地说,数字遗产是如何使用这些数据来创造过去环境的新体验,作为信息,解释,指南或艺术品,并最终帮助阐明新的研究问题和对我们声学遗产的探索。
Acoustic Heritage is one aspect of archaeoacoustics, and refers more specifically to the quantifiable acoustic properties of buildings, sites and landscapes from our architectural and archaeological past, forming an important aspect of our intangible cultural heritage. Auralisation, the audio equivalent of 3D visualization, enables these acoustic properties, captured via the process of measurement and survey, or computer based modelling, to form the basis of an audio reconstruction and presentation of the studied space. This paper examines the application of auralisation and audio creativity as a means to explore our acoustic heritage, thereby diversifying and enhancing the toolset available to the digital heritage or humanities researcher. The Open Acoustic Impulse Response (OpenAIR) library is an online repository for acoustic impulse response and auralisation data, with a significant part having been gathered from a broad range of heritage sites. The methodology used to gather this acoustic data is discussed, together with the processes used in generating and calibrating a comparable computer model, and how the data generated might be analysed and presented. The creative use of this acoustic data is also considered, in the context of music production, mixed media artwork and audio for gaming. More specifically to digital heritage is how these data can be used to create new experiences of past environments, as information, interpretation, guide or artwork and ultimately help to articulate new research questions and explorations of our acoustic heritage.
