Environmental sound perception of cochlear implant users

Environmental sound perception of cochlear implant users.

The purposes of this study were (1) to develop a new test of environmental sound perception, the Environmental Sounds Perception Test (EST), (2) to compare the performance of experienced cochlear implant (CI) recipients with that of age-equivalent normally hearing (NH) listeners using this new test, and (3) to pilot test its clinical use as a pre-to-post assessment tool. The closed-set EST cons...

Commentary: Environmental Sound Training in Cochlear Implant Users

Cochlear implants (CIs) are prosthetic devices developed for listeners with profound bilateral hearing loss. Despite considerable advances in CI hearing technology allowing for improved speech and language recognition, several studies have reported that the identification of common environmental sounds—even years after implantation plus high speech perception scores—prove difficult for most lis...

Music Perception in Cochlear Implant Users

Temporal Feature Perception in Cochlear Implant Users

For the perception of timbre of a musical instrument, the attack time is known to hold crucial information. The first 50 to 150 ms of sound onset reflect the excitation mechanism, which generates the sound. Since auditory processing and music perception in particular are known to be hampered in cochlear implant (CI) users, we conducted an electroencephalography (EEG) study with an oddball parad...

Assessment of sound quality perception in cochlear implant users during music listening.

BACKGROUND Although cochlear implant (CI) users frequently report deterioration of sound quality when listening to music, few methods exist to quantify these subjective claims. OBJECTIVE 1) To design a novel research method for quantifying sound quality perception in CI users during music listening; 2) To validate this method by assessing one attribute of music perception, bass frequency perc...
