- Problem 4. A point source emits sound waves uniformly in all directions. At distance 90.0 m from the source the sound intensity level is 15 dB. At what distance from the source is the sound intensity level 35 dB?A person standing 1.10 m from a portable speaker hears its sound at an intensity of 3.90 x 10-³ W/m². HINT (a) Find the corresponding decibel level. dB (b) Find the sound intensity (in W/m²) at a distance of 36.0 m, assuming the sound propagates as a spherical wave. W/m² (c) Find the decibel level at a distance of 36.0 m. dBA noisy factory machine produces a sound intensity of 1.00 x 10-5 W/m2 when measured 10 m from the machine. Assume that the sound spreads out uniformly into 3 dimensions for this set of questions. What is the sound power output of the machine? (Give your answer in mW.) What is the decibel level of the machine at 10 m? At what distance is the decibel level equal to 55 dB? (Give your answer in m.)
- The intensity level in decibels is defined as 10 log10(I/I0), where I0 is a reference intensity equal to the human threshold of hearing, 10–12 W/m2. What is the intensity of the threshold of pain, 120 decibels? answer is : 10° W/m2 I'm not sure how they got this answerYou and your roommate decide to throw a party. You rig up three speakers with a combined decibel level of 83.5 db. You know that speaker one is 78.0 dB and speaker 2 is 76.0 dB. The sticker on the back of speaker 3 is missing, so you will have to calculate how many decibels it is. How many decibels is the third speaker?Problem #4: What sound intensity level in dB is produced by earphones that create an intensity of 4.00 x 10-2 W/m2?
