The torsional deflection of a simple cylinder cannot radiate efficiently acoustic noise, but with particular boundary conditions the stator can radiate acoustic noise under torque ripple excitation. [8] Structure-borne noise can also be generated by torque ripple when rotor shaft line vibrations propagate to the frame [9] and shaft line.

In electrical circuits, ringing is an oscillation of a voltage or current.Ringing can be undesirable because it causes extra current to flow, thereby wasting energy and causing extra heating of the components; it can cause unwanted electromagnetic radiation to be emitted [citation needed]; it can increase settling time for the desired final state; and it may cause unwanted triggering of ...
Fans installed in a PC case can produce noise levels of up to 70 dB. Since fan noise increases with the fifth power of the fan rotation speed, [2] reducing revolutions per minute (RPM) by a small amount potentially means a large reduction in fan noise. This must be done cautiously, as excessive reduction in speed may cause components to ...
Turning up the fan setting is the only way to get a bit of white noise. You’re going to need the remote. Most of the functionality of the Cool Gen1 is controlled via the remote.
Molly Price of CNET compared the Invoke to Amazon Echo and Google Home, noting that the Invoke's metal outer casing design, smooth-turning volume control, and touchpad, "feels high-end, and that's good news for a speaker with a higher price tag than the Amazon Echo and Google Home." She also found "the Invoke's 360-degree sound to deliver ...
These earbuds have active noise cancellation and offer 360-degree audio for immersive sound. HD Voice Technology separates your voice from surrounding noise when you’re talking on the phone ...
