The mechanical measurements have been made by using two laser Doppler vibrometers (based on the well-known not-invasive optical measurement technique) coupled with the acoustic field measured by high-quality certified microphones. The recorded signals are analyzed by using well-established methods in time and frequency domains. The signals of the mechanical vibrations along the trachea and the larynx are compared with those of the acoustic ones. F","authors_text":"E. De Lauro, G. Buccheri, M. Falanga, S.
