Abstract
This paper demonstrates hardware and software used for 24 hour long audio recording in real sanitary sewer. Experiment setup is also described. Applications for recording and for its analysis were developed using LabVIEW. Analysis of audio recording were performed in time and frequency domains. Results of the analysis were used to characterize use of sanitary sewer during a day. Determined day patterns can be used to detect malfunction, blockage or leakage in sewer. Day characteristics can also be used to schedule maintenance works when sewer is the least used.
