| 1. | 41-ET also closely matches a number of other intervals involving higher harmonics.
|
| 2. | Moreover, it is plucked relatively closer to the bridge, which emphasizes higher harmonics.
|
| 3. | Some lock-in amplifiers also allow separate measurements of these higher harmonics.
|
| 4. | In the case of nonlinear systems, higher harmonics of the modulation frequency appear.
|
| 5. | Their output waveform is also perfectly sinusoidal without noise or higher harmonic output.
|
| 6. | Now we are well within the range of cymbals and other higher harmonic timbres.
|
| 7. | The pressure changes within a medium cause the wave energy to transfer to higher harmonics.
|
| 8. | By boosting high frequencies and overdriving the speaker or amplifier slightly, higher harmonics can be generated.
|
| 9. | For example, one waveform has an octave-unison effect where the higher harmonics fade in over time.
|
| 10. | Sirens generate low frequencies, but with high sound pressure levels distortion appears that leads to higher harmonics.
