The IEEE Technical Committee for Audio and Acoustic Signal Processing (AASP) will be launching a set of 'challenges' for specific problems in the AASP technical scope in order to encourage the devlopment of systems that would have comparable and repeatable results and at the same time help better defining each of the problems, provide standard datasets for each problem, suggest evaluation metrics and thus motivate researchers to take part in the whole attempt. For further details visit the IEEE - AASP challenges webpage.

'Detection and Classification of Acoustic Scenes and Events'
Dimitrios Giannoulis, Emmanouil Benetos, Dan Stowell, Mathieu Lagrange,
We have proposed to organise a challenge on the performance evaluation of systems for the detection and classification of acoustic events, which falls into the field of computational auditory scene analysis (CASA) . Humans are able to follow specific sound sources in a complex audio environment with ease and the development of systems that try to mimic this behaviour is an open problem, especially in the case of overlapping sound events.
Currently, there is no active challenge or competition in the CASA field that could encourage research and development towards this direction or provide a source of references of various methodologies and approaches, like the MIREX competition for music information retrieval  or the SiSEC evaluation for signal separation . Perhaps the closest is TRECVID Multimedia Event Detection but this is for audio visual event detection .
