Why does signal recovery via cochlear implants fail in noisy environments, despite advanced signal processing?

💡 Explanation

Cochlear implants rely on electrical stimulation. Noise causes auditory nerve fibers to fire asynchronously because the noise obscures the intended temporal patterns; therefore, signal recovery is impaired, rather than being overwhelmed by spectral smearing which is somewhat mitigated by filtering, or the less impactful saturation of automatic gain control.

• If a lexicographer aims to include an example sentence demonstrating the nuanced usage of a polysemous word within a dictionary entry, which consequence is most likely?
