Daniel Leon Johnson Edit Profile

Aeronautical engineer

Daniel Leon Johnson, American aeronautical engineer. Achievements include development of the analysis that is used by the current International Standard that relates noise exposure to noise induced hearing loss; development (with others) of the measurement metric for environmental noise; determination of the safety limits of low frequency sound; determination in part of the safety limits of some types of impulsive sounds; two patents in field.
