Abstract

The acquisition of acoustic properties such as absorption and transmission-loss coefficients is necessary for the analysis and synthesis of acoustic materials. Because of its accuracy, the impedance tube is the preferred method of measurement. However, current implementations require a strong technical background in acoustics and considerable time to produce results. The system described in this work will use a microcontroller to automate the measurement process and expedite the delivery of information to a non-expert end-user.
