Question
Which of the following characteristics of sound differentiates the sounds of equal frequency and amplitude?
- Timbre
- Wavelength
- Time period
- Oscillations
Hint:
Timbre is a common term for distinctive tone characteristics.
The correct answer is: Timbre
- Timbre is the characteristic of a sound, due to which it is possible to differentiate between sounds of the same amplitude (loudness) and the same frequency (pitch).
- The quality or timbre of the sound is that characteristic that enables us to differentiate between sounds that have the same pitch and the same loudness.
