Logarithm - is the exponent of base 10 that equals the value of a number In decibel formulas how should values be logically arranged when comparing two numbers (V1 / V2) - If you expect a gain, place the higher number first. If you expect a loss, place the smaller number first. Explain negative decibel values - measurement just means "less than before," or in this case, "less than the reference level. It does not mean the basic unit it represents has a negative value Decibel - describes...

Electret Microphone - A type of condenser microphone. It has prepolarized material which is applied to the microphone's diaphragm or backplate. This provides a permanent, fixed charge for one side of the capacitor configuration. This permanent charge eliminates the need for the higher voltage required for powering the typical condenser microphone, so it can be powered using small batteries and normal phantom power. Lavalier Microphone (lav /lapel) - It is a small microphone designed to be ...

ADA requirements Signal Separation in Racks - Group equipment together according to their function to protects against crosstalk among cables through EMI Chemical Systems - Replace the room air with fire inhibiting gas, such as halon, CO2, or halocarbon agents (that contain chlorine, fluorine, or iodine either individually or in some combination). ...

EAD, Equivalent Acoustic Distance - Is the farthest distance one can go from the source without the need for sound amplification or reinforcement to maintain good speech intelligibility. It is a design parameter dependent on the level of the presenter and the noise level in the room PAG - Potential Acoustic Gain is the potential gain that can be delivered by the sound system without ringing and before feedback occurs. It is based upon the number of open microphones, and the distances betwee...
