Abstract

This dataset presents the indoor air temperature collections using the novel technique of Acoustic travel time TOMography (ATOM) in the ultrasonic frequency range. The presented measuring system employs early reflections as sound propagation paths in addition to the travel time of the direct path, effectively combining room acoustics with tomography techniques. The data was collected across various measurement scenarios within the climate chamber laboratory at the Building Physics Department at the Bauhaus-University Weimar. Additionally, the measurements data regarding the phase shift compensating of the utilized preamplifier in the setup are provided. These measurements served to assess the effectiveness of the new ultrasonic measurement system which was presented in the co-published article (Dokhanchi et al., 2024). The developed algorithms provided in this Dataset offers a valuable reference for researchers in the field of acoustic tomography especially those focusing on indoor applications, and the researchers involved in indoor climate monitoring where non-contact indoor air temperature measurements are required.
