First of all, experiments were performed in a semi-anechoic room, focussing on obtaining the acoustic characteristics which were considered important for gear diagnostics. Also, an experiment was performed in which it was shown that a smartphone could detect a broken tooth fault on a helical gear at relatively low load. ER -
