    This study shows that activated prostheses enable 12 of 13 subjects to perceive environmental sounds and aid lipreading. While awareness of speech is improved, speech understanding remains limited.

    Area of Science:

    • Audiology
    • Biomedical Engineering
    • Neuroscience

    Background:

    • Hearing prostheses aim to restore auditory function.
    • Understanding speech and environmental sounds is crucial for daily life.

    Purpose of the Study:

    • To evaluate the efficacy of activated prostheses in sound perception.
    • To assess the impact of prostheses on speech awareness and understanding.
    • To investigate the effect on environmental sound identification and lipreading.

    Main Methods:

    • 13 subjects with activated prostheses were tested.
    • Sound perception was measured at normal environmental intensities (35-65 dB SPL).
    • Speech awareness, understanding, environmental sound identification, and lipreading abilities were assessed.

    Main Results:

    • 12 out of 13 subjects responded to sound with activated prostheses.
    • Prostheses facilitated awareness of speech but not comprehension.
    • Environmental sound identification and lipreading performance showed improvement.

    Conclusions:

    • Activated prostheses provide a degree of sound awareness in challenging acoustic environments.
    • While not enabling full speech comprehension, these devices offer benefits for environmental sound recognition and lipreading support.
