Hello friends,
Most recently one of our Fm's was mentioning about the Sensitivity of the Speakers, before that i thought "Its a dry area" to look on speaker selection.
Later i read some articles and understood some information on Sensitivity and How Sensitivity can impact the speaker selection equal to the importance of Watts handling.
So below is my observation
Sensitivity of speakers are measured in Decibels in short DB or db and more than say 115 db Would be more turn into noise normally(this is just approx value)
Rule of Sound reproduction: Volume need to be doubled i.e W*2 to attain +3 in Sensitivity or DB
i.e When my speaker is 85 DB @ 1W in 1 meter
so to increase the DB from 85 to 88, i need to supply (1*2 w)=2 Watts
For Example: I have two 100 Watts speakers with one SP1: 86 db and other SP2:90 db sensitivities.
SP1- Response
So on playing with 100w amplifier with SP1 i would achieve
(Increase in watts supplied 1+2+4+8+16+32+64
Increase in DB according to watts 86,89,92,95,98,102,105)
SP2-Response
(Increasing in watts supplied 1+2+4+8+16+32+64
Increase in db according to watts 90,93,96,99,102,105,108)
So what is observed\understand is
Speaker with 90db@63W = Speaker 86db@127W
