Sound Power Level of a speaker is computed from the sound power of the speaker.
Sound power from the speaker is the total sound energy emitted by a speaker per unit time.
How this sound power is related to the electric power given to the speaker. For example if I give 6W electric power to the speaker then sound power from the speaker will be only 6W.
If you want to know the acoustic power that you will get from the speaker you need to search the efficency of the speaker . Efficency*ElectricalPower = acousticPower
Maxim Dorogov Thanks for your reply.
Let me clarify my doubt in clear, I hope you can give a detailed clarification.
basically I'm new to acoustic modelling. I need to model PA system via EASE.
I'm allowed to use only 0.75W electric tapping power, but EASE suggest to divide 0.75W to all frequency listed. For example it has 21 Frequency then the power has to be divided to all the frequency equally (0.75/21) . We use pink noise. I have following doubts
1)Does the speaker develops sound in all frequencies or only particular frequency?
2)Why for pink noise I need to divide the electric power equally to all the frequency?
Unqualified comments :-
Time weighted negotiating of a mass, collection of matter considering field effects ( say gravity, possibly friction and so on) with a directional effort is work, forced displacment sort of effects.
Rate of doign work is power (watts) , sort of time rated expense of energy. Describing power has nothing to do with underlying phenomenon.
Most important thing to understand or find or reconcile is
proxy of or displacments/field
proxy of or efforts,
and of course ratio of expended against recoved power offers clues about nature of losses , mostly thermal, and proverbial efficiency etc.
