Two study reports on real-world acoustics and real-world HA benefit

Two study reports on real-world acoustics and real-world HA benefit (ESR6-T3.1; ESR6-T3.2). T3.1. A literature review on the effects of contrasting HA signal-processing schemes on speech perception, listening effort and overall preference. T3.2: A literature review of knowledge relating to the variation of acoustical characteristics in real-world auditory communication situations, and assessment of appropriate methods to condense and control the parameters of this variation in laboratory experimental setups
