A method of tuning a notch filter in a data storage device (DSD) including the notch filter and a shock detection system includes: adjusting pulse width modulator (PWM) frequency settings of a spindle drive signal; detecting a maximum noise level of an output signal of the shock detection system while adjusting the PWM frequency settings; and selecting a notch filter frequency corresponding to a PWM frequency setting at which the maximum noise level of the output signal of the shock detection system is detected.

An isolating system for dampening vibrations to or from audio equipment includes a mounting bracket secured to a support surface and a lower isolator assembly engaged with the mounting bracket. An upper isolator assembly engages the audio equipment and is positioned above the lower isolator assembly. The upper and lower assemblies are engaged with one another via aligned pairs of resilient, vibration-dampening isolators and associated connector members. The connector members extend between the isolators and are long enough to prevent direct contact between the upper and lower isolators. The isolating system is configured to allow a user to pivot the audio equipment about a vertical axis to change the position of the equipment in a horizontal plane. The isolating system is further configured to allow the user to pivot the audio equipment about a horizontal axis to change the position of the equipment in a vertical plane.

An electronic device can include a first electronic component, a second electronic component, and an energy dampener positioned between and in contact with the first electronic component and the second electronic component. The energy dampener in this example includes a carbon nanotube-aerogel matrix including carbon nanotubes embedded in an aerogel with a rubber composited therewith.
