A singer refuses to use a microphone, believing amplification 'weakens' the natural voice over time. This belief is:
-
A
Unfounded; microphone use does not alter vocal fold tissue or weaken intrinsic laryngeal muscles
-
B
Correct because the brain reduces laryngeal effort when it detects external amplification
-
C
Partially correct for condenser microphones but not for dynamic microphones
-
D
Supported by studies showing reduced diaphragmatic activity with amplification
