Dichotic listening is a psychological test commonly used to investigate selective attention and the lateralization of brain function within the auditory system. It is used within the fields of cognitive psychology and neuroscience . In a standard dichotic listening test, a participant is presented with two different auditory stimuli ...
Since subjective listening tests are time-consuming, expensive and impractical for everyday use, it was beneficial to substitute listening tests with objective, computer-based methods. Steered by the ITU-R Task Group 6Q, a group of leading sound quality experts developed a new objective model for sound quality: PEAQ. These contributors were:
Mannheim Harbour. Mannheim Harbour, named Rhein-Neckar-Hafen Mannheim, is a river port on the Rhine in Mannheim, at the confluence of the Rhine and the Neckar in Baden-Wurttemberg. It consists out of 4 main harbour areas Handelshafen, Rheinauhafen, Altrheinhafen and Industriehafen, which are divided into 14 single harbour basins and 3 river docks.
Codec listening test. A codec listening test is a scientific study designed to compare two or more lossy audio codecs, usually with respect to perceived fidelity or compression efficiency. Most tests take the form of a double-blind comparison. Commonly used methods are known as "ABX" or "ABC/HR" or "MUSHRA". There are various software packages ...
Audio equipment testing. Audio equipment testing is the measurement of audio quality through objective and/or subjective means. The results of such tests are published in journals, magazines, whitepapers, websites, and in other media. Those who test and evaluate equipment can be roughly divided into two groups: "Objectivists", who believe that ...
MUSHRA. MUSHRA stands for Multiple Stimuli with Hidden Reference and Anchor and is a methodology for conducting a codec listening test to evaluate the perceived quality of the output from lossy audio compression algorithms. It is defined by ITU-R recommendation BS.1534-3. [1]
Selective auditory attention. Selective auditory attention, or selective hearing, is a process of the auditory system where an individual selects or focuses on certain stimuli for auditory information processing while other stimuli are disregarded. [1] This selection is very important as the processing and memory capabilities for humans have a ...
A codec listening test is a scientific study designed to compare two or more lossy audio codecs, usually with respect to perceived fidelity or compression efficiency. Potential flaws. ABX is a type of forced choice testing. A subject's choices can be on merit, i.e. the subject indeed honestly tried to identify whether X seemed closer to A or B.
