Mechanic's stethoscopes usually are similar to medical ones, except that instead of the typical "bell" they use a straight pipe. As far as noise cancelling headphones, the thing is that the gain required should not be much, perhaps much less than for noise cancelling audio headphones. I will post the results if I get anywhere with this idea. |
