Acoustic travel time tomography for simultaneous indoor air temperature and airflow measurements

Developing the technique of Acoustic travel timeTOMography (ATOM) for monitoring the indoor air temperature and airflow measurements represents asignificant 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 acrossthe 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 temperatureand 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
