Properties of maximum length sequence and nonlinear volterra slice otoacoustic emissions
… of cochlear function. A new technique, based onMaximum Length Sequences (MLSs) enables stimulus rates of up to 5000 clicks/s to beused, and gives increased speed and sensitivity of testing. Volterra slice otoacousticemissions (VSOAEs) can be extracted from the response using this technique. …

Characterization of the head-related transfer function using chirp and maximum length sequence excitation signals
Both chirp (or sweep) and maximum length sequence (MLS) excitation signals are used to obtain measurements of the head-related transfer function (HRTF) for the Knowles electronic manikin for acoustic research (KEMAR), resulting in remarkably low relative error between the two measurement methods. …

Underwater Acoustic Localisation in the context of Autonomous Submersibles
… utilises an acoustically transmitted maximum length sequence (MLS) signal which provides extremely high robustness against interference by stochastic and systematic disturbances which are typical for underwater environments. The azimuth is obtained via hyperbolic positioning with …

Room reconstruction and navigation using acoustically obtained room impulse responses and a mobile robot platform
This work explores the design and effectiveness of a robot that uses a combination of active sonar and a pseudo-random acoustic signal to navigate and reconstruct an unknown environment. The robot sends the pseudo-random signal into the environment and records the resulting response. This response …
