By what factor must the sound intensity be increased to increase the sound intensity level by...
What is the sound intensity level B, in deabels, of a sound wave whose intensity is 10 times the relerence intensity e I Express the sound intensity namerically to the nearest integer 101)? Review 1 Constants1 Periodic Tabla View Available Hints) Learning Goal: To understand the decbel scale The decbel scale is a logaithmic scalo for measuring the sound intonsity level Because the decibel scale is ogarithmic, it changes by an additive constant when the intensity as measurod in W/m...

QUESTION The power output of a sound system is increased by a factor of 25. By what factor should you adjust your distance from the speakers so the sound intensity is the same? PRACTICE IT Use the worked example above to help you solve this problem. A small source emits sound waves with a power output of 82.9 w. (a) Find the intensity 3.05 m from the source. W/m2 (b) At what distance would the intensity be one-fourth as much...
What is the sound level of a sound with an intensity of I = 1.00×10-6 W/m2? Give your answer in dB units. A: 60.00 B: 79.80 C: 106.13 D: 141.16 E: 187.74 F: 249.69 G: 332.09 H: 441.69 Now the intensity of this sound is increased to a value of 38.0 times of its original intensity. What is the new increased sound level? Give your answer in dB units. A: 5.62 B: 8.16 C: 11.83 D: 17.15 E: 24.86 F:...
What is the sound intensity level (in units of dB) when the intensity of sound is 5.05 mW/m2?
Miranda is measuring the sound intensity level for a speaker by holding a sound level meter. The intensity of the sound wave at her location is 2.6e-07 W/m2. (a) What is the sound intensity level (SIL) recorded on the meter at Miranda's location? i got the answer of 54.14dB (b) The volume of the speaker is turned down until the intensity of the sound being produced decreases by a factor of 150. What does Miranda's sound level meter read now?...
What is the sound intensity level in the air near a jackhammer when the sound intensity level is 105 dB ?
26 27 26) By what amount does the intensity level increase when you triple the power to the source of sound? A)4.8 dB B) 6.0 dB C) 9.5 dB D) 3.0 dB E) 12 dB 27) A transverse wave traveling along a string transports energy at a rate P. If we want to double this rate, we could A) increase the amplitude of the wave by a factor of 2 B) increase the amplitude by a factor of2 C) increase...
A certain sound level increases by an additional 20 dB. By how much does the intensity increase? The intensity increases by a factor of 200. The intensity increases by a factor of 100. The intensity increases by a factor of 20. The intensity increases by a factor of 2. The intensity does not increase.
What is the sound intensity level of a sound with an intensity of 2.4×10−6 W/m2 ? In dB
