Whether a person speaking
at a distance of 20 feet will be adequately recorded while the mic/recorder
is in a pocket depends on the sound pressure level that reaches the mic and
the sensitivity of the mic and the gain of its amplifier.
Even more important when it comes to recording speech is the
intelligibility. At 20 feet in a typical classroom, the mic will be
well into the reverberant field and even if there's sufficient
amplitude, the recorded speech may be difficult to understand.
