Some attempted improvements on the armonica included adding keyboards, placing pads between the bowls to reduce sympathetic vibrations, and using violin bows.
12.
All of the wood seen in the concert hall has been sealed to the concrete in order to prevent any sympathetic vibrations.
13.
To reduce sympathetic vibrations, the two turbines should turn at speeds with few common multiples, for example 7 : 3 speed ratio.
14.
In addition to planned harmonies, reverberating notes often excite sympathetic vibrations in neighbors, further enriching the sound, the Physics Today authors said.
15.
If the sound that hits it has such a frequency the object will start to vibrate along ( sympathetic vibration or resonance ).
16.
Most electronic keyboards also have a sustain pedal that holds notes and chords, but only high-end digital keyboards reproduce the sympathetic vibration effect.
17.
Through sympathetic vibration, they enhanced the timbre of the melody line, thus serving the baryton's role as the primary melody instrument in this music.
18.
In the realm of physics, Huygens'observations are related to resonance and the resonant coupling of harmonic oscillators, which also gives rise to sympathetic vibrations.
19.
Resonating type bass trap achieves absorption of sound by sympathetic vibration of some free element of the device with the air volume of the room.
20.
They use sympathetic vibration of the other strings ( such as when the sustain pedal is depressed ) and full pedal sets can now be replicated.
