Test measurements

In preparation for the measurement expedition, acoustic outdoor measurements were conducted on the lawn in front of the Acoustical lab on the TU/e campus. Despite of the low temperatures, the weather circumstances were good, it was totally dry and every now and then the sun showed itself. We carried out a line measurement over approximately 88 m. The goal of this measurement was to test the measurement technique in an outdoor situation with lots of background noise.

After the setup was built it became clear that it was even more noisy than expected. The main disturbers were: the railroad, construction (traffic) noise, spluttering students, loading and unloading labor, etc. The main challenge was to do qualitatively reliable measurements over high source-receiver distances, despite of the high background noises. The first results look promising, although the measurement method needs some fine-tuning.
