Abstract:

Acoustic noise measurements were obtained within Cessna T-41A and T-41C trainer aircraft during various phases of ground and airborne operation. Factors contributing to speech interference and auditory risk were identified, and recommendations are provided relative to improving voice communications and reducing auditory risks. Ambient noise within the T-41A and T-41C interferes significantly with speech, but this problem can be reduced when earplugs, such as the V-51R, are worn. The attenuation provided by the V51R earplugs should prevent temporary or permanent noise-induced hearing loss. Author
