The most notable noise in your kitchen probably comes from your microwave timer, and if today’s a day where you just can’t handle the noise, here’s how you can put it on silent mode.
The microwave auditory effect, also known as the microwave hearing effect or the Frey effect, consists of the human perception of sounds induced by pulsed or modulated radio frequencies. The perceived sounds are generated directly inside the human head without the need of any receiving electronic device.
Sounds commonly used to indicate that a button has been pressed are a click, a ring or a beep.

The whole system noise temperature looking at cold sky (2.7 kelvin in the microwave band) was 17 kelvin. This gave such a low noise figure that the Mariner IV space probe could send still pictures from Mars back to the Earth , even though the output power of its radio transmitter was only 15 watts , and hence the total signal power received was ...
The cosmic microwave background radiation (CMBR), for example, is a weak microwave noise filling empty space which is a major source of information on cosmology's Big Bang theory of the origin of the Universe.
A beep is a short, single tone, typically high-pitched, generally made by a computer or other machine.The term has its origin in onomatopoeia.The word "beep-beep" is recorded for the noise of a car horn in 1929, and the modern usage of "beep" for a high-pitched tone is attributed to Arthur C. Clarke in 1951.
Beep, beep" is onomatopoeia representing a noise, generally of a pair of identical tones following one after the other, often generated by a machine or device such as a car horn. It is commonly associated with the Road Runner (commonly interpreted as "meep meep") in Looney Tunes cartoons featuring the speedy-yet- flightless bird and his ...
This allows the TWT to have a very low noise output, a major advantage of the design. More usefully, this process is much less sensitive to the physical arrangement of the tube, which allows the TWT to operate over a wider variety of frequencies. TWT's are generally at an advantage when low noise and frequency variability are useful. [6] [7]
