The term "db" typically refers to "decibel," a unit of measurement for sound intensity and other quantities. The concept of the decibel was developed in the early 20th century, with significant contributions from engineers like Alexander Graham Bell. It was later formalized in the 1920s by the Bell System for telecommunications applications. The decibel scale is logarithmic and has since become widely used in various fields, including acoustics, electronics, and telecommunications.

A sound of 20 dB intensity is twice as loud as one of 10dB?
No, it is 10 times louder. dB is a logarithmic scale; every 10 dB, the intensity increases by a factor of 10. Thus, 10 dB is 10 times louder than 0 dB, 20 dB is 10 times louder than 10 dB, and 30 dB is 10 times louder than 20 dB.No, it is 10 times louder. dB is a logarithmic scale; every 10 dB, the intensity increases by a factor of 10. Thus, 10 dB is 10 times louder than 0 dB, 20 dB is 10 times louder than 10 dB, and 30 dB is 10 times louder than 20 dB.No, it is 10 times louder. dB is a logarithmic scale; every 10 dB, the intensity increases by a factor of 10. Thus, 10 dB is 10 times louder than 0 dB, 20 dB is 10 times louder than 10 dB, and 30 dB is 10 times louder than 20 dB.No, it is 10 times louder. dB is a logarithmic scale; every 10 dB, the intensity increases by a factor of 10. Thus, 10 dB is 10 times louder than 0 dB, 20 dB is 10 times louder than 10 dB, and 30 dB is 10 times louder than 20 dB.

How many times louder is 80dB compared to 40dB?
80 dB is 10 times louder than 70 dB, and 70 dB is 10 times louder than 60 dB, and so on. Therefore, 80 dB is 1000 times louder than 40 dB.

How do you converts ohms to dB?
You must find a resistance value for 0 dB as reference. If 1 Ohm = 0 dB then 10 ohms = 20 dB and 100 ohms = 40 dB.
