Microphone Specifications
   Directivity       
   Your choices are...         
   Omnidirectional       Microphone sensitivity is equal or nearly equal in all directions. 
   Directional       Microphone sensitivity is strongest in a particular direction or directions.  Below are several types of directional sensitivity patterns. 
   Bidirectional       Microphone is strongly sensitive in two directions, typically opposite each other. 
   Semi cardioid       Moderately directional microphone, with a maximum direction of sensitivity, and whose minimum direction is typically opposite, or 180° from, the maximum. 
   Cardioid       Unidirectional microphone with an effective sensitivity angle of approximately 130°, or fairly well focused.  Best rejection is directly opposite the direction of maximum sensitivity.  So named because of the resemblance of the directivity graph to a traditional depiction of the human heart. 
   Supercardioid       Microphone with a narrower sensitivity angle, or pickup, than a cardioid microphone, typically 115°.  Also has some sensitivity opposite the maximum pickup direction. 
   Hypercardioid       Tighter pickup angle than a supercardioid (105°), but with more rear pickup. 
   Other       Other unlisted, combination, or specialized microphone directivity pattern. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Frequency Response       Frequency response is the range of frequencies for which the microphone maintains a constant sensitivity within defined boundaries. Variation from this "linear" or "flat" sensitivity is given in dB; bounds that the define the linear frequency response will be in the form of ±3dB, -1dB/+4dB, etc. 
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
   Dynamic Range       Dynamic range is the range of sound pressure levels (dB) for which the microphone will meet its performance specifications; it is limited on the low end by the inherent noise of the acoustic system and on the high end by the maximum sound pressure level. The standard unit for measuring sound pressure level (SPL) is the deciBel (dB) with a reference pressure of 20 micro Pascals (20 μPa), which is the human hearing threshold. 
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
   Microphone Sensitivity:       Measure of how responsive or "hot" a microphone is.  Sensitivity may be given in millivolt output per Pascal of sound pressure, or may be specified in dBV (dB), in which case it is typically a negative number.  A correctly specified signal should exceed the inherent noise of the system yet not overload the preamplifier. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Signal to Noise Ratio       Logarithmic ratio of the signal level produced by a standard pressure signal (e.g., 94 dB SPL) to the noise floor.  S/N Ratio is typically expressed in dBV, or often dB for short. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Impedance       Impedance is the resistance to flow of alternating current.  Low impedance microphones exhibit values such as 100-500 ohms, whereas high impedance microphones can be 10,000 ohms or more. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Piezoelectric Technology       Piezoelectric Devices make use of the Piezoelectric Effect to perform an electronic or mechanical. The piezoelectric effect is found on some crystals, which acquire a charge when compressed, twisted or distorted. This provides a convenient transducer effect between electrical and mechanical oscillations. Several types of devices are available: actuators, sensors, motors, transducers, etc. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

Microphone Dimensions Values are typically nominal.
   Nominal Diameter      Different diameter microphones have differing dynamic characteristics. In general, larger diaphragms are more sensitive and have narrower frequency response; individual microphone specifications may vary. Microphone diameter is usually a nominal measurement. The most common choices are listed but may not be exact. A 1/2" microphone may actually be 13.2mm, for example, and a 25.2mm diameter microphone would be listed as 1".
   Your choices are...         
   1/8"         
   1/4"         
   1/2"         
   1"         
   Other       Other unlisted microphone size. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Actual Diameter / Size       True diameter or width measurement. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Thickness / Height       Thickness or height of microphone; for assemblies or long probe microphones, this value represents the length. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
