Characterization of the head-related transfer function using chirp and maximum length sequence excitation signals
… The HRTF measurements obtained with an external probe microphone are compared with those obtained with the standard in-ear microphones that the KEMAR is equipped with, to reveal that care should be taken to select a probe microphone that has a low susceptibility to multipath interference. An …

Development of a Multiple Microphone Probe Calibrator
… presents the theory, design, and validation of a microphone calibrator used to calibrate multiple microphones simultaneously. This work was done in conjunction with the development of an acoustic energy density probe, which was used to validate the calibrator. The probe uses multiple microphones …

Turbulent Boundary Layers over Rough Surfaces: Large Structure Velocity Scaling and Driver Implications for Acoustic Metamaterials
… the resulting sound waves were measured with a probe microphone. Acoustic surface waves were found via Fourier analysis in time and space. Standing acoustic surface waves were identified. Membrane response properties were measured to obtain source condition characteristics for turbulent boundary …

The exploitation of acoustic-to-seismic coupling for the determination of soil properties
… has been accomplished using a mechanical shaker. Probe microphone measurements of the Type-II wave allowed the flow resistivity and tortuosity of the material to be determined using a rigid frame model, whilst deduction of elastic moduli has been made from signals received at buried geophones. It …
