frequency response defines range of sound mic can reproduce

flat responsse - reproduces all noises with no distortion of sound

shaped response - more sensitive to some frequency ranges than other

increasd sensitivity in upper mid range adds clarity to vocals

descrteaded senseitivyt to low frequencies - reduces pickup of room noise and vibration and counteracts buildup of base when mic is used close to source which is called proximity effect

mics with shaped response works better than flat response - 

some mics allow frequency response to be adjusted 

most common- low frequency roll off control - mic sensitivity to low frequency sound is reduced 

high pass filter allows higher frequencies to pass 

polar pattern - the area a mic covers

omnidirectional - equally sensitive to sounds from any direction 

cardiod - shape of a heart - popular in studios bevause good at isolating the vocaks or instruments

supercardiod / hypercardiod/ ultracardiod

bidirectional/figure 8

signal to noise ratio 

impedence - measure of resistance to flow of energy 

Maximum SPL - the maximum decibel that is comfortable for hearing. Painful sound starts at 120 db SPL
