How will an increase in amplitude and power affect dB?
The decibel (dB) scale is logarithmic. An increase of power by a factor of 10 is an increase of +10 dB. If power increases by a factor of 100, that is equivalent to +20 dB.The decibel (dB) scale is logarithmic. An increase of power by a factor of 10 is an increase of +10 dB.

What are the notes for the Db scale 2nd octave?
it depends what instrument you playy
What is the melodic minor scale of D flat major?

A sound of 20 dB intensity is twice as loud as one of 10dB?
This statement is not accurate. The decibel (dB) scale is logarithmic, not linear. An increase of 10 dB represents a tenfold increase in sound intensity. So, a sound of 20 dB intensity is actually 10 times louder than one of 10 dB, not twice as loud.
What are the notes in the A flat melodic minor scale?
Going up the scale: Ab Bb Cb Db Eb F G Ab Going down the scale: Ab Gb Fb Eb Db Cb Bb Ab It like a natural minor scale but has a raised 6th and raised 7th ascending the scale.
Prove dbm plus dbm equals db?
The decibel scale is a logarithmic scale where each change in three dB represents a power factor change of two. (3 dB is power times two, 6 dB is power times four, 9 dB is power times 8, etc. Similarly, -3dB is power divided by two, -6 dB is power divided by four, etc.) Zero dB is assigned some arbitrary reference power. One example is 1 mV across 600 ohms. If you double the voltage into a constant resistance, the power quadruples, so 2 mV would be +6 dB, 4 mV would be +12 dB, etc. The letter after dB is the reference power. In the case of dBm, it means that 0 dB is 1 milliwatt, so 2 milliwatt is +3 dB, etc. There are many dB scales, such as dBa, used in sound measurements. Still, fundamentally, 3 dB is a doubling of power, -3 dB is a halving of power, so, for any arbitrary scale, say dBq, then saying +6dBq is saying a power four times higher than 0 dBq. In the end, dBm plus dBm is delta dB, with no scale.
What scale determines how loud something is?
The scale that determines how loud something is called the decibel scale. It measures the intensity of sound waves and allows us to quantify and compare the loudness of different sounds. The scale ranges from 0 dB (absolute silence) to around 120-130 dB (threshold of pain).
Is a sound that measures 100-dB ten times louder than a 10-dB?
90
