| Abstract | ||
| Background: Cochlear implants (CIs) have transformed hearing rehabilitation for individuals with severe to profound hearing loss, significantly improving speech perception and communication. However, CI users, especially children, often face challenges in noisy environments, which can hinder speech intelligibility and overall auditory performance. To address these challenges, various noise management strategies have been employed in CI devices to enhance auditory experiences in complex listening conditions. Conclusion: Advanced signal processing algorithms, such as noise reduction and adaptive beamforming, work to enhance speech signals while minimizing background noise allowing users to focus on critical auditory cues. Directional microphones improve the signal-to-noise ratio (SNR) by focusing on sounds from the front and reducing ambient noise from other directions. Assistive listening devices, like FM systems, transmit the speaker’s voice directly to the CI, improving SNR in complex auditory environments like classrooms or noisy public places. Additionally, environmental modifications, such as improving room acoustics and using sound-absorbing materials, also play a vital role in enhancing listening experiences for CI users. By integrating these strategies, CIs can significantly improve speech recognition, reduce listening effort, and enhance auditory performance in challenging, noisy settings. | ||
