“…The temperatures obtained from ATOM system were consistently compared to those measured by highly precise NTC thermistors for accuracy assessment. Analysis indicates Root Mean Square Error (RMSE) values of less than 0.5 K between ATOM temperatures and NTC thermistors (Dokhanchi et al 2024 [5,6]).…”

Developing the technique of Acoustic travel time TOMography (ATOM) for monitoring the indoor air temperature and airflow measurements represents a significant breakthrough for modern buildings especially those prioritizing thermal comfort. While conventional measurement methods are limited to individual measuring points, ATOM technique can measure the climatic parameters’ distribution across the entire room with high spatial resolution utilizing sound velocity measurements along various propagation sound paths. This research outlines the ongoing development of the ATOM technique for simultaneous measuring the indoor air temperature and airflow velocity at the Department of Building Physics at the Bauhaus‐University Weimar. It presents both the challenges confronted and the solutions developed in establishing a straightforward measuring system that can optimally fulfil the requirements of the indoor climate projects.
