You might already know that the reason is because a cell phone doesn’t transmit all of the sounds that the human voice creates. Specifically, cell phones don’t transmit very low-frequency sounds (below about 300 Hz) or high-frequency sounds (above about 3,400 Hz). The voice can and typically does make sounds at very high frequencies in the “treble” audio range (from about …

To determine frequency responce a simple condensor mic attach to a PC can be used. I use software called DL4YHF's Spectrum Lab to do frequency analays. Condensor mics have very flat frequency responce, flat enough for …
