If the sound level in a room is increased from 50 dB to 60 dB, by what factor is the pressure amplitude increased ?

If the sound level in a room is increased from 50 dB to 60 dB, by what factor is the pressure amplitude increased ?

If the sound level in a room is increased from 50 dB to 60 dB, by what factor is the pressure amplitude increased ?

(a) Sound with intensity larger than 120 dB appears painful to a person. A small speaker delivers 2.0 W of audio output. How close can the person get to the speaker without hurting his ears? (b) If the sound level in a room is increased from 50 dB to 60 dB , by what factor level is the pressure amplitude increased?

Sound level /loudness at any point in a room is increased from "50dB" to "60dB" by increasing the pressure amplitude, if final pressure amplitude is "K" times that of initial. Find the value of (K^(2))/(5)

A certain sound level is increased by an additional 30 dB, Find the factor by which (a) its intensity increases and (b) its pressure amplitude increases.
