Question

Statement 1: Unit of loudness is decibel (dB).
Statement 2: Timbre of sound depends on the shape of the waveform.

• A. Statement 1 is true, statement 2 is false
• B. Statement 1 is false, statement 2 is true
• C. Both statements are true
• D. Both statements are false

Answer 1

The correct option is C Both statements are true

Unit of loudness is decibel (dB).
Timbre (or quality) of sound helps in differentiating between sounds of the same frequency and same amplitude. It depends on the shape of the waveform.
Hence, both statements are true.
