A small speaker delivers `2 W` of audio will one detect `120 dB` intensity sound ? [Given reference intensity of sound as `10^(-12) W//m^(2)`]

The intensity of sound of 50 dB (Take reference of intensity 10^-12 W/ m^2 )

What is the intensity of sound of 70 decibel ? ( Given the reference intensity I_0 = 10^(-12) " watt"//m^(2) )

Find intersity of sound in dB if its intensity in Watt// m^(2) is 10^(-10) .

Find the intensity level of a sound wave that has an intensity of 10^(-5) Wm^(-2) .

What is the level of loudness of a sound of intensity 10^(-12) W//m^2 ?

(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?

Find the intensity level of a sound wave in decibles of a sound wave whose intensity is 10^(-10) cm^(-2) . Take zero level of intensity = 10^(-12)Wm^(-2) .

Find the displacement ammplitude amplitude of amplitude of particles of air of density 1.2 kg//m^(3) ,if intensity, frequency and speed of sound are 8 xx 10^(-6) w//m^(2), 5000 Hz and 330 m//s respectively.

A sound differs by 6 dB from a sound of intensity equal to 10(nW)/(cm^2) . Find the absolute value of intensity of the sound.
