How To Calculate Sound Pressure & Sound Pressure Level
For one amplifier to produce sound twice as loud as another in decibels, you need 10 times more wattage output. An amplifier rated at 100 WPC is capable of twice the volume level of a 10 WPC amp, an amplifier rated at 100 WPC needs to be 1,000 WPC to be twice as loud. This follows the logarithmic scale mentioned above.... I can notice 1/2 db though. 3 db is what you get from doubling amplifier power. A 10 fold increase in power (ie 10 to 100 watts) gets you a 10 db difference. 3db is very easy to hear. A 10 fold increase in power (ie 10 to 100 watts) gets you a 10 db difference. 3db is very easy to hear.

Just to ask for more clarification, does this mean then that negative decibels would be more for, say, deeper/more bass things? I'm trying to think of what a negative decibel sound would, well, sound like. I get louder = higher decibels, but I'm having trouble making sense of a negative in terms of 0 being the human threshold....Based on this equation, how much more powerful is an 800 W amplifier than a 200 W amplifier, in decibels? For voltages, Equation 4.4 is used ( ). If you increase a voltage level from 100 V to 1000 V, what is the increase in decibels?

- More generally the maximum, minimum, and mean directivities of any antenna are always at least 1, at most 1, and exactly 1. For the half-wave dipole the respective values are 1.64 (2.15 dB ), 0, and 1.
- With NAudio you can use the WaveFileReader and Mp3FileReader classes to get access to the sample data within the file as a byte array. Then you would need to read through the file and get the sample values (e.g. for 16 bit audio, every two bytes represents a short).
