A Power Efficient Audio Amplifier Combining Switching and Linear Techniques [PDF]

, 1998
Integrated Class D audio amplifiers are very power efficient, but require an external filter which prevents further integration. Also due to this filter, large feedback factors are hard to realise, so that the load influences the distortion- and transfer

Comparison of Acceptable Noise Level Generated Using Different Transducers and Response Modes

Neural Plasticity, 2018
The acceptable noise level (ANL) was defined by subtracting the background noise level (BNL) from the most comfortable listening level (MCL) (ANL = MCL − BNL).

Localization and Rendering of Sound Sources in Acoustic Fields [PDF]

, 2015
Disertační práce se zabývá lokalizací zdrojů zvuku a akustickým zoomem. Hlavním cílem této práce je navrhnout systém s akustickým zoomem, který přiblíží zvuk jednoho mluvčího mezi skupinou mluvčích, a to i když mluví současně.
