Purpose The study investigated the effect of a short computer-based environmental sound training regimen on the perception of environmental sounds and speech in experienced cochlear implant (CI) patients. Method Fourteen CI patients with the average of 5 years of CI experience participated. The protocol consisted of 2 pretests, 1 week apart, followed by 4 environmental sound training sessions conducted on separate days in 1 week, and concluded with 2 posttest sessions, separated by another week without training. Each testing session included an environmental sound test, which consisted of 40 familiar everyday sounds, each represented by 4 different tokens, as well as the Consonant Nucleus Consonant (CNC) word test, and Revised Speech Perception in Noise (SPIN-R) sentence test. Results Environmental sounds scores were lower than for either of the speech tests. Following training, there was a significant average improvement of 15.8 points in environmental sound perception, which persisted 1 week later after training was discontinued. No significant improvements were observed for either speech test. Conclusions The findings demonstrate that environmental sound perception, which remains problematic even for experienced CI patients, can be improved with a home-based computer training regimen. Such computer-based training may thus provide an effective low-cost approach to rehabilitation for CI users, and potentially, other hearing impaired populations.

The main purpose of this study was to provide an independent corroboration of open-set word recognition in some of the better cochlear-implant patients. These included the Chorimac, Nucleus (one group from the U.S.A. and one group from Hannover, Germany), Symbion, Duren/Cologne and 3M/Vienna implants. Three experiments are reported: (1) word recognition in word lists and in sentences; (2) environmental sound perception, and (3) gap detection. On word recognition, the scores of 6 Chorimac patients averaged 2.5% words and 0.7% words in sentences correct in the French tests. In the German tests, the scores averaged 17% words and 10% words in sentences for 10 Duren/Cologne patients, 15% words and 16% words in sentences for 9 3M/Vienna patients, and 10% words and 16% words in sentences (3% to 26%) for 10 Nucleus/Hannover patients. In the English tests, the scores averaged 11% words and 29.6% words in sentences for l0 Nucleus-U.S.A. patients, and 13.7% words and 35.7% words in sentences for the 9 Symbion patients. The ability to recognize recorded environmental sounds was measured with a closed set of 18 sounds. Performance averaged 23% correct for Chorimac patients, 41% correct for 3M/Vienna patients, 44% correct for Nucleus/Hannover patients, 21% correct for Duren/Cologne patients, 58% correct for Nucleus/U.S.A. patients, and 83% correct for Symbion patients. A multidimensional scaling analysis suggested that patients were, in part, utilizing information about the envelope and about the periodic/aperiodic nature of some of the sounds. Gap detection thresholds with a one-octave wide noise centered at 500 Hz varied widely among patients. Typically, patients with gap thresholds less than 40 ms showed a wide range of performance on speech perception tasks, whereas patients with gap-detection thresholds greater than 40 ms showed poor word recognition skills.

Abstract The overwhelming majority of test measures to assess adult and pediatric cochlear implant candidacy, efficacy, and progress are based on speech perception. Nonlinguistic sounds have received comparatively little attention, despite their central importance for incidental learning, daily living and environmental sound awareness. The purpose of this review is to: 1. Highlight the importance of nonlinguistic sound perception, 2. Discuss currently available pediatric nonlinguistic sound perception profiles and behavioral measures, and 3. Describe both the Nonlinguistic Sounds Test (NLST) for adults and adolescents as well as the pediatric Picture-identification Nonlinguistic sounds Inventory for Children (PicNIC).

I identify meaning as a property of utterance, the situated instance of language use, and locate its presence in the soundscape as a point of reference for all humans that constitute a particular acoustic community. My starting point is the premise that our experience of aural space and the soundscape are so profoundly connected to our experience of what it is to be human that there is a direct relationship, established over millennia, between the environments in which communication takes place and the ways in which we communicate. Further to this, I suggest that sound is the binding agent in a dialogic relationship between consciousness, environment and context. I argue that this binding operates through a process in which differing degrees of awareness and recognition of soundscape features, structures and inter-relations facilitate a shift between basic hearing functions and more informed modes of listening. This leads, in turn, to expression through mimicry, performativity and utterance. In other words, the dialogic characteristic of the relationship is located in the reciprocity between hearing, speaking and environmental phenomena.   The central hypothesis of this paper states that, without sound binding us into this dialogic relationship with environment and context, we would not have been able to develop inter-human sounds in order to function as social beings. I argue that this relationship underpins the formation of linguistic tools that both help structure, and provide access to the perceptual and conceptual knowledge of the world that we store in memory. This combined knowledge structure informs both our external engagements and sense of self. Both my initial premise and hypothesis are supported by theoretical and practical research, including participant observation and feedback from a series of sound installations designed to progress the inquiry.

The author reflects on the past decades with reference to predictions of several paradigm shifts offered in the 1990s, including a broad range of issues covering acoustics, psychoacoustics, the role of the composer, compositional models, environmental sound perception, soundscape composition, and the integration of music and context. Contemporary developments that were not predicted, such as the proliferation of compressed audio, the rapid development of sound studies, the elimination of electroacoustic music from state-funded broadcasting, and the proliferation of mobile listening and online sound databases, are also discussed.
