Abstract:
In this study, we tested whether the speech recognition, through radio communications, of cochlear implant (CI) users inside a noisy helicopter cockpit is adequate for safe flight.
Method:
Speech recognition tests (sentences, numbers and disyllables) through a very-high-frequency radio were administered to 12 CI users in a soundproof booth, inside a helicopter with the engine turned off and turned on.
Results:
In quiet environments, radio communications were impacted only for disyllable intelligibility, but in noisy situations, all tests were affected.
Conclusions:
CI subjects did not achieve the auditory levels recommended by the International Civil Aviation Organization.

Background and Environment Affect Phenotype
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
