According to weber's law, the constant for loudness of tones measured in decibels is 0 .05.
00:07
Now, this means that a person should be able to tell the difference between a standard of 50 decibel and a comparison stimulus of how many decibels.
00:15
So from here, we know that the formula is k equals delta i divided by i.
00:22
K in this case is the weber fraction constant.
00:25
Delta i is the change intensity.
00:27
I is the initial intensity or the standard standard stimulus.
00:33
Now in our case, we know the weber fraction is 0 .05.
00:40
And we know that the standard intensity or stimulus i is 50 decibel.
00:52
So we want to calculate delta i.
00:54
So delta i equals k multiplied by i.
01:02
So 0 .05 multiplied by 50.
01:06
So from there you can see that delta equals 2 .5 decibel...
