Johnson–Nyquist noise (thermal noise, Johnson noise, or Nyquist noise) is the electronic noise generated by the thermal agitation of the charge carriers (usually the electrons) inside an electrical conductor at equilibrium, which happens regardless of any applied voltage.

Aeroacoustics is the study of noise generated by air movement, for instance via turbulence, and the movement of sound through the fluid air. This knowledge was applied in the 1920s and '30s to detect aircraft before radar was invented and is applied in acoustical engineering to study how to quieten aircraft .
Mains hum, electric hum, cycle hum, or power line hum is a sound associated with alternating current which is twice the frequency of the mains electricity.The fundamental frequency of this sound is usually double that of fundamental 50/60 Hz, i.e., 100/120 Hz, depending on the local power-line frequency.
Different types of noise are generated by different devices and different processes. Thermal noise is unavoidable at non-zero temperature (see fluctuation-dissipation theorem), while other types depend mostly on device type (such as shot noise, [1] [3] which needs a steep potential barrier) or manufacturing quality and semiconductor defects, such as conductance fluctuations, including 1/f noise.
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.
The Houston Chronicle praised the series for "offer[ing] many and varied academic activities, plenty of play-oriented pursuits, incentives to spur and reward achievement and all the interactive trimmings – cool characters, great 3-D graphics and snappy sound effects", describing the World Kindergarten, 1st Grade and 2nd Grade as superlative ...
Experiments and Observations on Electricity is a treatise by Benjamin Franklin based on letters that he wrote to Peter Collinson, who communicated Franklin's ideas to the Royal Society. [ 1 ] [ 2 ] The letters were published as a book in England in 1751, and over the following years the book was reissued in four more editions containing ...
