A mechanics stethoscope is sometimes useful in these cases, tho the
character of the noise will be different than when heard thru the air.
Else try a simple wooden stick or long screw driver.  Put one end
against the suspected part and the other against your ear just in front
of the opening so that your ear is pushed closed.  Of course care is
needed when maneuvering the implement near moving belts and pulleys.
  If the noise is simply from a squeaking belt, it should at least
change when you tighten or loosen it.
