The average human being can hear sounds of up to 20 kHz frequency;
therefore, most of the sounds made by the tiny parts inside a computer — regardless of volume — are inaudible to the human ear, because their frequencies are often in the 100 kHz range — too high for the human ear to detect. A.therefore, most of the sounds made by the tiny parts inside a computer — regardless of volume — are inaudible to the human ear, because their frequencies are often in the 100 kHz range — too high for the human ear to detectB.
therefore, because the frequency of the sounds made by the tiny parts inside a computer are often in the
100 kHz range, that makes them inaudible to the human ear
C.therefore,
the frequencies of the tiny parts inside a computer—regardless of volume—often in the 100 kHz range,
are inaudible to the human earD.
most of the sounds made by the tiny parts inside a computer—regardless of volume—are therefore inaudible to a
human being because of their frequencies being too high for the human ear
to detect themE.
most of the sounds made by the tiny parts inside a computer—regardless of volume—
