Listening in noisy places is challenging, especially with hearing impairment. Unfortunately it is unavoidable in many social, educational and work situations. Speech understanding in continuous noise eg white noise is well understood, but in real life the background is typically people talking. This project used men, women, and children talking to evaluate speech understanding in normal-hearing people, cochlear implant users, and normal-hearing people using a cochlear implant simulation. Results showed that the use of continuous backgrounds underestimates difficulties experienced by cochlear implant users. Children talking in the background was surprisingly demanding, perhaps suggesting an evolutionary trait of not ignoring children.
