In this paper, we present an indoor 3D positioning method for smartphones using acoustic signals. In our proposed 3D Frequency Division Multiplexing-Phase Accordance Method (3D FDM-PAM), four speakers simultaneously emit burst signals comprising two carrier waves at different frequencies to enable the rapid calculation of the position of the smartphone. Through experiments, we show that 3D FDM-PAM can achieve a standard deviation of less than 2.8 cm at 7.8 measurements per second. The worst
