In a musical instrument, the component that increases the sound after production is the

• A. The vibrating element
• B. The part of the instrument that amplifies sound
• C. The outer ear
• D. The mechanism of sound production

Answer: (B)

Amplification is about making the produced sound louder, not creating it. After the vibrating element sets the sound in motion, the instrument’s body, resonance chamber, or air column acts as a resonator that boosts those vibrations. This part converts some of the vibrating energy into larger sound waves that project outward, so the overall volume increases. The outer ear is for hearing sound, not generating or boosting it. The mechanism of sound production describes how the initial vibration starts, not how it’s amplified. So the component that increases the sound after production is the part of the instrument that amplifies sound, such as the body, soundboard, or resonator.
