WebSensitivity, measured in decibels or dB, is the figure we use to measure the comparative “loudness” of a speaker. Using an input signal of one-watt, we measure the output signal from the speaker at a distance of one metre. For a 12″ guitar speaker this commonly gives us a value of between 96 and100dB. This is what we refer to as the ...

WebThe sensitivity is measured in mV per pascal or in dB relatively to 1 V/Pa. Because 1 V/Pa is a very large value, the sensitivity in dBV/Pa (dB re 1V/Pa) will always be a negative value. The sensitivity in decibels is defined as 20·log₁₀ (V₁/V₀) where V₀ is the reference level of 1 V/Pa and V₁ is the output voltage of the microphone. Web29 mei 2024 · Essentially, sensitivity is a measure of how loud a pair of headphones will play at a given power level. If headphone A has a higher sensitivity rating than headphone B at a power level of one milliwatt, then the audio it produces will be louder at that volume, and it can be considered to be louder in general.

WebA simple measure of sensor resolution is the number of pixels per millimeter. Analog CCD cameras have rectangular pixels (larger in the vertical dimension). This is a result of a limited number of scanning lines in the signal standards (525 lines for NTSC, 625 lines for PAL) due to bandwidth limitations.
