A team of students at the Johns Hopkins University’s Whiting
School of Engineering has designed for NASA a new stethoscope that delivers
accurate heart- and body-sounds to medics who are trying to assess astronauts’
health on long missions in noisy spacecraft.
Space is serene, because no air means no sound. But inside
the average spacecraft, with its whirring fans, humming computers and buzzing
instruments, is about as raucous as a party filled with laughing, talking
people.
