How Is DB Gain Calculated? Gain is defined as the ratio of the output power to the input power in dB. Assume that the input power is 10 mW (+10 dBm) and the output power is 1 W (1000 mW, +30 dBm). The ratio will be 1000/10 = 100, and the gain will be 10
How Many Times More Intense Is A 60 DB Sound Than A 30 DB? This sound 60 db is 1000 times longer than 30 dB. How many times louder is a 60 dB sound than a 10 dB sound? A 10-dB rise is a 10-time leap in loudness. That means an 80-dB sound (a vacuum
What Is That Noise I Think It Is Helicopter? Helicopters are well known for the loud sound they make as their blades spin, but many people do not know what causes the noise. The researchers explained that most of the noise is generated by the helicopter’s main rotor Why does it sound like a helicopter?
What Is The Relationship Between Intensity And Loudness? The intensity of a sound is the power of the sound in Watts divided by the area the sound covers in square meters. The loudness of a sound relates the intensity of any given sound to the intensity at the threshold of hearing. It is measured in
