The resultant loudness at a point P is `n` dB higher than the loudness of `S_1` whoch is one of the two identical sound sources `S_1` and `S_2` reaching at that point in phase. Find the value of n.

Two identical sound S_1 and S_2 reach at a point P is phase. The resultant loudness at point P is n dB higher than the loudness of S_1 the value of n is :

Two identical sounds s_(1) and s_(2) reach at a point P phase. The resultant loudness at a point P is not higher than the loudness of s_(1) . The value of n is

Two identical sounds s_(1) and s_(2) reach at a point P phase. The resultant loudness at a point P is not higher than the loudness of s_(1) . The value of n is

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)

Two sources of sound S_1 and S_2 vibrate at same frequency and are in phase. The intensity of sound detected at a point P as shown in the figure is I_0 . (a) If theta equals 45^@ , what will be the intensity of sound detected at this point if one of the sources is switched off ? (b) What will be the answer of the previous part if theta= 60^@ ?

When beats are produced by two progressive waves of same amplitude and of nearly same frequencies then the maximum loudness of the resulting sound is n times the loudness of each of the component wave trains. The value of n is

In the shown fig. S1 and S2 are two identical coher- ent sources of sound, separated by a distance d. A receiver moves along the line XY (which is parallel to line S1 S2) to detect the intensity of sound at various points on the line. Distance of line XY from line S1 S2 is D (gt gt d) . Point O is the foot of perpendicular bisector of the line S1 S2 on XY. Distance of first intensity maxima (on line XY) measured from O is y. Find percentage change in value of y if the temperature of air increases by 1%.
