A seismograph is used to measure ground movement or vibrations on the Richter scale.
Loudspeakers, headphones, buzzers, sirens, door bell chimes...
No. But there are mathematical patterns that are used in music. And all sounds are vibrations. These vibrations can be decomposed into sets of sine curves.

Vibration exciters are active systems and can generally be used for high-precision excitation of structures to vibrations and for the specific reduction of structural vibrations.
vibrations
Vibrations are measured using instruments called accelerometers, which detect and quantify the movement of an object. These devices can be attached to the object being measured or placed nearby to capture the vibrations. Accelerometers convert the vibrations into electrical signals that can be analyzed to determine the frequency, amplitude, and other characteristics of the vibrations. Other tools and methods used for vibration measurement include laser vibrometers, strain gauges, and spectral analysis techniques.
A seismograph is an instrument used to measure and record vibrations and movement in the Earth and on the ground. These instruments are no longer as widely used, as there are modern instruments used to separately measure or record these movements, such as seismometers.
