Timbre

Definition

Timbre is the quality or color of a sound that distinguishes it from other sounds of the same pitch and volume. It is determined by the complex waveform produced by the source.

5 Must Know Facts For Your Next Test

1. Timbre allows us to differentiate between different musical instruments playing the same note at the same loudness.
2. It is influenced by the harmonic content and envelope of a sound wave.
3. The human ear can detect subtle differences in timbre, which aids in identifying sources of sounds.
4. In acoustics, timbre is often analyzed through Fourier analysis to understand its frequency components.
5. Real-world sounds usually consist of a fundamental frequency and multiple overtones or harmonics that contribute to their unique timbre.
