Arctic soil soundscapes

Sample soil soundscape recordings collected in common garden experiment at Abisko Scientific Research Station in September - October 2020. Files have not been pre-processed (i.e., are in their original format as saved onto recording devices). Before our analysis, all recordings were low pass filtered to remove signals above 5 kHz. We also applied a band pass filter at 500 Hz to remove self noise that appeared intermittently on some recorders. Our analysis focused on signals primarily betwen 50 Hz - 2 kHz, and we recommend that other researchers limit their analysis to this range in order to avoid noise artifacts from recorders that we occasionally observed at high frequencies.

2020年9月至10月，于阿比斯库科学研究站（Abisko Scientific Research Station）的同质园实验（common garden experiment）中采集的土壤声景样本录音。所有文件均未经过预处理，即保留录制设备存储时的原始格式。在开展本分析前，我们对所有录音进行了低通滤波，以去除5 kHz以上的信号；同时施加了500 Hz的带通滤波，以消除部分录制设备间歇性出现的自身噪声。本研究的分析重点主要集中在50 Hz至2 kHz的信号区间，同时建议其他研究者也将分析范围限定在此区间内，以规避我们在高频段偶尔观测到的录制设备噪声伪影。
