Final answer:
The two types of microphones commonly used are body microphones and hand-held microphones. Body microphones are wireless devices concealed in the hair and secured to the body, while hand-held microphones are preferred by singers for their voice support.
Step-by-step explanation:
There are two types of microphones commonly used: body microphones and hand-held microphones. Body microphones, also known as wireless microphones, are small devices concealed in the hair and secured to the body. They are commonly used in theater productions and rely on a radio system. Hand-held microphones, on the other hand, are favored by singers as they provide excellent support to the voice without much alteration to the sound. However, they are rarely used in theater as they disrupt the illusion of realism.
