====== Interactive Interface For Auditory Perception Experiments ====== | Author | James Traer | | Affiliation | McDermott Lab, Brain and Cognitive Sciences Department, MIT | | Code | will be uploaded to www.jamestraer.com when I get the website up and running | Abstract: ===== - Introduction ===== Although audio processing technology has advanced tremendously in recent years, state-of-the-art machine hearing algorithms still lag far behind the human auditory system when required to extract acoustic information from noisy real-world environments. Exactly what processing techniques are utilized by the human auditory system to perform these tasks are largely unknown and this is an active area of research. A better understanding of how audio signals are processed in the brain may provide inspiration for improved machine listening algorithms as well as clinical benefits for the hearing impaired. ===== - Yesterday's research methodology ===== One way to study how the audio processing of the human brain is to measure the ability of human listener's to perform auditory classification tasks in difficult conditions. Such tasks could include word comprehension, spatial localization, melody extraction, texture identification, volume comparisons, etc... In each case the human listener must ignore distracting information to extract one particular feature of the acoustic signal. By precisely controlling the acoustic signal heard by the listener and measuring the listener's performance as a function of both the signal, and distracting noise, the performance capabilities of the human auditory system can be inferred. However one source of difficulty in such experiments is the large number of variable parameters that characterize real-world sources, both the insources of information, and the distractors Pair-wise comparison is one commonly used methodology.
