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 …

July 21, 2020. For most people, the audible hearing spectrum ranges from about 20 Hz to 20 kHz. That’s roughly 20,000 different frequencies to deal with in any given track—from the deepest kick drum the brightest cymbals and strings. Thankfully, by breaking the full frequency spectrum into smaller frequency ranges, we can easily control the different elements of any mix.

For any device that uses a standard speaker driver, the Hz-KHz value is the range of audible sound vibrations that the speaker can produce. It’s generally labeled as the “frequency response” and expressed in hertz, with kilohertz being a thousand hertz. So the typical frequency response for headphones, twenty hertz to twenty thousand ...
Wideband audio - Wikipedia
https://en.wikipedia.org/wiki/Wideband_audio
Wideband audio, also known as wideband voice or HD voice, is high definition voice quality for telephony audio, contrasted with standard digital telephony "toll quality". It extends the frequency range of audio signals transmitted over telephone lines, resulting in higher quality speech. The range of the human voice extends from 100 Hz to 17 kHz but traditional, voiceband or …
