Avixa Exam CTS Topic 1 Question 22 Discussion

A cardioid microphone has a heart-shaped (or ''cardioid'') pick-up pattern that captures sound primarily from the front while rejecting sound from the rear. The pattern shown for Type(b) aligns with a typical cardioid response, featuring a coverage angle of approximately 131, which indicates its directional sensitivity towards the front and rejection from the back.
