A spherical source is radiating sound waves with a potency of 55.0 watts. A) At what distance is the observer from the source that detects an intensity of 7.0 x10^-2 B) What’s the level of intensity (decibels) at this distance
The intensity from a point source of waves at a distance of 1 m from the source is 10 W/m^2. At a distance of 10 m the intensity is 1000 W/m^2 100 W/m^2 1 W/m^2 0.1 W/m^2 0.01 W/m^2
One source emits spherical waves and another emits plane waves. For which source does the intensity measured by a detector of fixed size fall off more rapidly with distance? Which statements are true? 1.) The intensity of the plane source falls off more rapidly. 2.) The measured intensity for the spherical source decreases as 1/r2. 3.) The measured intensity for the plane source decreases as 1/r. 4.) The measured intensity for the plane source does not decrease. 5.)The measured intensity...
5. By how many decibels do you reduce the sound intensity level due to a source of sound if you double your distance from it? Assume that the waves expand spherically. dB 6. The sound in a classroom is 63000 times as intense as the minimum threshold of hearing. What is the intensity level of this sound in decibels? dB
Spherical sound waves are emitted from a 2.00-W source. Assuming that the energy of the waves is conserved, what is the intensity at 0.60 m from the source? Submit Answer Tries 0/99 What is the intensity at 3.10 m from the source? Submit Answer Tries 0/99

SOUND WAVES 12. Observer 2 is three times as far from a point (spherical) source of sound as is observer 1. The ratio I2/I1 of the intensities (observer 2 intensity to observer 1 intensity) of the sound detected by the observers is a) 9 b) 1/9 c) 1/3 d) 3 13. Which of the following frequencies would correspond to a sound with an ultrasonic frequency? a) 100Hz b) 1000Hz c) 10000Hz d) 100000Hz
An intensity detector can be moved along a straight track. a source of spherical waves is placed at one end of the track. When the detector is 2 m away from the source, it measures an intensity of 80 W/m2. What distance do we need to move the detector from that position to get a measurement 13 dB lower?
Help please!!!! By how many decibels do you reduce the sound intensity level due to a source of sound if you double your distance from it? Assume that the waves expand spherically.
An outside loudspeaker (considered a small source) emits sound waves with a power output of 111 w (a) Find the intensity 10.7 m from the source W/m2 (b) Find the intensity level in decibels at that distance. dB (c) At what distance would you experience the sound at the threshold of pain, 120 dB?
