The smallest change in frequency that a
person can usually perceive is 0.3 percent.
00:00:09.527 --> 00:00:14.501
So we are going to add 0.3 percent
to this given frequency *f*
00:00:14.821 --> 00:00:18.632
and find the high-end or the upper
frequency that is detectible
00:00:19.018 --> 00:00:22.850
and then we will subtract the
three percent *f* away from *f*.
00:00:23.178 --> 00:00:26.945
And find the lower frequency
that would be audible.
00:00:28.421 --> 00:00:33.578
And so we have the original frequency
of 500 Hertz plus 0.3 over hundred
00:00:33.578 --> 00:00:38.210
that turn this 0.3 percent into
a decimal times 500 Hertz.
00:00:38.538 --> 00:00:40.996
This gives 501 and a half Hertz.
00:00:41.680 --> 00:00:47.650
And then the first lower frequency
that would be audible
00:00:48.225 --> 00:00:53.461
is going to be 500 hertz minus three
percent which gives 498.5 Hertz.
