Selection of in situ impulse responses from Finnish rock art sites

This dataset contains a selection of impulse responses (24) recorded at prehistoric rock art sites in Finland. The dataset serves as supplementary material for the article ‘Reflected Encounters at Hunter-Gatherer Rock Art Sites by the Water’, authored by R. Rainio, J. Shpinitskaya, P. Rinkkala, J. Pekkanen, P. Kesäniemi, and M. Ojanen. Data collection objectives and methods are discussed in detail in the article. The work was part of the Academy of Finland funded project ‘Acoustics and auditory culture at hunter-gatherer rock art sites in Northern Europe, Siberia and North America’ (2018–2023) at the University of Helsinki (https://www.helsinki.fi/en/researchgroups/acoustics-of-sacred-sites).

Each wav file contains one impulse response recorded with a Neumann KM183 omnidirectional condenser pressure microphone and a Zoom F8 or H6 portable audio recorder (96-kHz sampling rate and 24-bit depth). Either the ‘pop’ sound of a 40 cm diameter latex balloon or a 10-second logarithmic sine sweep serves as the excitation signal. The file name indicates the following information:
̶ name of the site
̶ type of the site
̶ distance of the recording location from the painted or reference rock (m)
̶ time of recording (winter [-12 to +2° C] / summer [+12 to +25° C])
̶ excitation signal (pop / sweep)

The table below lists the rock art sites in question with their key characteristics (name of the site; municipality; formation = type of rock formation; height = height of the paintings above the water; category = categorization of the sites into unchanged or changed in terms of topography and acoustics; fieldwork = time of fieldwork).

本数据集包含24条在芬兰史前岩画遗址录制的脉冲响应（Impulse Responses）。本数据集是R. Rainio、J. Shpinitskaya、P. Rinkkala、J. Pekkanen、P. Kesäniemi及M. Ojanen合著的论文《水边狩猎采集者岩画遗址的反射式相遇》的补充材料。数据采集的目标与方法在该论文中有详细论述。此项工作是芬兰科学院资助、赫尔辛基大学开展的项目《北欧、西伯利亚及北美狩猎采集者岩画遗址的声学与听觉文化》（2018–2023）的一部分（项目链接：https://www.helsinki.fi/en/researchgroups/acoustics-of-sacred-sites）。

每个wav文件包含一条脉冲响应，由Neumann KM183型全向电容压力麦克风与Zoom F8或H6便携式录音机录制（采样率96kHz，位深24bit）。激励信号（Excitation Signal）为直径40厘米乳胶气球的“爆裂”声，或10秒对数正弦扫频信号。文件名包含以下信息：
- 遗址名称
- 遗址类型
- 录制位置与带岩画岩石或参考岩石的距离（米）
- 录制时间（冬季[-12至+2°C]/夏季[+12至+25°C]
- 激励信号类型（爆裂声/扫频）

下表列出了相关岩画遗址的关键特征，包括：遗址名称、所属市镇、岩层类型、岩画距水面高度（米）、类别（按地形及声学特征分为未改变或已改变）、田野调查时间。
