11. The sound level in decibels (dB) is given by dB-10log(101x), where x is the intensity of the sound given in W/cm2. a) Determine the...
A sound source in all directions with the same intensity. If at point A, which is 3.00 m from the source, the sound intensity level is 80.0 dB. At what distance from the source is point B, if the intensity level of the sound in it is 60.0 dB? determine the distance from the source to point B
Sound from source 3 has a sound intensity level that is 8.3 dB less than sound from source 1. By what factor is the sound intensity from source 3 less intense than the sound intensity from source 1? (Assume the sound intensities for sources 1 and 3 are I1 and I3, respectively.)
5. A sound source has an intensity I1 and when its sound level is measured at a fixed distance the found value is 70 dB. The source increases its intensity to I2 and when its sound level is measured at the same distance the found value is 96 dB. What is the I2 / I1 ratio?
The sound intensity level of a dog's bark is 40 dB. The intensity of a rock concert is 10,00 times that of the dog's bark. What is the sound intensity level of the rock concert? 90 dB O 75 db 2050 dB O 70 dB 40,000 dB
You measure the sound intensity level as 70.5 dB at a location that is 4.31 m from a localized sound source. How far away from the source must you be for the intensity level to fall to 60.5 dB?
audio system 1 produce an intensity level of B=90.0dB, and
system 2 produces an intensity level of B=93.0 dB. the
corresponding intensities (in W/m2) are I1 and I2. Determine the
ratio I1/I2
PHY 206/206L Term: Spring 2020 Name: Due Date: 02/10/2020 HW10 (1401-3) Comparing Sound Intensities (10 pts) Audio system i produce an intensity level of B =90.0 dB, and system 2 produces an intensity level of 8 = 93.0 dB. The corresponding intensities (in W/m?)arel, and 12. Determine the...
A point source of sound generates a 200 Hz tone. The wave has an intensity of 2.2×10−8 W/m2 at a distance of 3 m from the source. Find the total sound power at the source. At what distance from the source is the decibel level below 15 dB? What is the intensity of the sound at this distance?
A) What is the intensity (in W/m2) of a sound that has a level 3.00 dB lower than a 4.15 ✕ 10−9 W/m2 sound? B) what is the intensity in W/m2 of a sound that is 10.0 dB higher than a 4.15 x10-9 wW/m2 sound?
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...
