Speaker Sensitivity Speaker sensitivity is a measure of how loud a speaker will play at a given input power or at a given input voltage. Sensitivity is normally measured with a 1 watt power input or a 2.83 Vrms voltage input. The acoustic output is normally measured in an anechoic space at a distance of 1 meter from the speaker.

And, when revisions are made in subsequent versions of a speaker, one needs to ask if they truly went back and retested both anechoic and in-room measurements again. Sensitivity listed on a line item ad seems to be more of a general guideline at a selected frequency range noted on basic tech spec sheets.

As we see, 50% of the speakers measured thus far deviate no more than 1/2 a decibel from their advertised sensitivity. The CEA-2034 standard states that a ±1.5dB variance between measurement setups is considered "good", and using that parameter rises the conformity to 75%. The brand with the worst results is by far Klipsch.

There is an international standard that defines sensitivity, and it specifies that sensitivity be referred to SPL @ 1m for 2.83V input. The actual measurement can be made at any distance and input level, but must be calculated back to 1m and 2.83V equivalent.

What is Sensitivity in Speakers? Know This Before You …
https://greatestspeakers.com/what-is-sensitivity-in-speakers/
How to measure sensitivity? By tradition, the sensitivity of a speaker is measured by placing an SPL (sound pressure level) meter or a measurement microphone precisely one meter away from the speaker’s front and making sure that the amplifier is delivering only one watt of power to the speaker. Now measure the results in decibels, and you have a sensitivity rating …

Sensitivity is an absolute quantity, the smallest absolute amount of change that can be detected by a measurement. Consider a measurement device that has a ± 1.0 volt input range and ± 4 counts of noise, if the A/D converter resolution is 2 12 the peak-to-peak sensitivity will be ± 4 counts x (2 ÷ 4096) or ± 1.9mV p-p. This will dictate ...

from 1 Pascal of sound pressure will have a sensitivity of 0 dB (equal to the reference). A microphone producing twice as much output voltage for the same sound pressure will have a sensitivity rating 6 dB greater while one producing 1/10 as much output voltage will have a sensitivity rating 20 dB less.
