A stereo speaker is rated at P1000 = 52 W of output at 1000 Hz. At 20 Hz, the sound intensity level LaTeX: \betaβ decreases by 1.3 dB. What is the power output P

The  value of the power is  

Explanation:

From the question we are told that

   The  power  rating

    The frequency is  

    The  frequency at which the sound intensity decreases  

     The decrease in intensity is by

Generally the  initial intensity of the speaker  is mathematically represented as

Generally the intensity of the speaker after it has been decreased is

So

=>

=>  

=>

=>

taking atilog of both sides
