Use the CB (Critical Band) concept and the chart below to predict whether the following pairs of tones, when heard simultaneously at the same amplitude, will evoke a consonant or a dissonant sensation. Explain how you know. (Consider the first member of each pair to be the centre frequency for this exercise.)

Expert Solution
Step 1
To say whether frequencies are consonant or disconsonant we have to calculate the difference. If the difference of the frequencies is lower than bandwidth then they are disconsonant and if difference greater than bandwidth then it is consonant. And in question we are asked to categorize depend upon critical band and we have a table of those critical band frequencies and bandwidths. The bandwidth will be nearly 100 up to central frequency 500 Hz
(1)200Hz and 280Hz
f1-f2=280-200=80Hz and it lower than 100.so it is disconsonant
