Because it is not necessary, and providing that bandwidth would increase cost and complexity. While the full range of 20Hz-20KHz is required for proper rendering of music, telephony, by standard, only requires a 3.5KHz bandwidth. You can hear and understand the spoken voice with only this range. You do not need the extended musical range.
What is the frequency range of an OE
315mhz
The frequency range of FM signal is 88hz to 108hz.
Audio output frequency is that range of frequencies that can be heard. For humans, that is generally considered to be the range of 20Hz to 20kHz.
To find the range in a frequency chart, first identify the highest and lowest values in the data set. Subtract the lowest value from the highest value: Range = Highest Value - Lowest Value. This calculation gives you the spread of values represented in the frequency chart.
The entire spectrum of sounds is called the "audio frequency range." It represents the range of frequencies that humans can hear, typically from 20 Hz to 20,000 Hz.
The entire range of electromagnetic frequencies is called the electromagnetic spectrum. This spectrum includes all forms of electromagnetic radiation, from radio waves to gamma rays.
Lock range is the input frequency range of the PLL over which out frequency changes in step with input frequency, where as capture range is the frequency range over which oput starts to responds to input frequency change.

The piano has the largest frequency range of any instrument, spanning from around 27.5 Hz for the lowest note to over 4,000 Hz for the highest note. This broad frequency range allows the piano to cover a wide spectrum of sounds and tones.
Iridium satellites operate in the L-band frequency range, specifically between 1616 MHz and 1626.5 MHz for their communication systems. This frequency range is used for both voice and data transmissions, enabling global coverage. The satellites utilize a unique polar orbit to provide connectivity across the entire Earth, including remote areas.
The broadcasting frequency range is from 300kHZ to 3400kHZ.
315mhz
The frequency range of FM signal is 88hz to 108hz.
The electromagnetic spectrum is the entire range of electromagnetic radiation, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Each type of radiation has a different wavelength and frequency.
5MHz
The frequency range of a cymbal typically ranges from 1,000 Hz to 5,000 Hz.
