The first part of knowing how to run church audio is knowing the equipment.  In the simpliest form, a person sings into a microphone.  The microphone then sends the audio signal to the sound system.  The sound is then processed and amplified and sent out to the speakers which then turns the audio signal into sound waves.  Therefore, there are input devices, processing devices, and output devices.  This article covers the types of input devices.  read more »

"Is there a difference between volume and decibel level?"

Volume is not a well-defined measure of sound.  Decibel is defined...as a ratio.

If you have two audio signals, and one is a ten times stronger than the other, you can say it is 10dB stronger. If it is 100x stronger it is 20dB, if it is 100x weaker, it is -20dB. It's a logarithmic formula.

Sound pressure levels (SPL) given in dB refer to 20microPascal at 0dB, which is actually around the threshold level of hearing anything at all.  read more »

Sound comes from vibrations caused by fluctutations in the air pressure. In fact, that's how the ear drum works.  read more »
