In which band is the difference?
A is the untouched sound and B has one frequency band raised or lowered. After each answer, the applied curve appears so that it can be compared with what was heard.
Adjusting the listening level
The volume is raised until the noise is heard clearly and comfortably. If a voice had to be raised to talk over it, it is too loud. Turning it up further does not improve any exercise.
