At a distance of 1,048.7 away from the plane, you record a sound intensity level of 74.82 decibels. If you move such that the new sound intensity level is 90.74 decibels, how far are you away from the plane (in meters)? Note: In the space below, please enter you numerical answer. Do not enter any units. If you enter units, your answer will be marked as incorrect.You 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 #5: What is the intensity of a sound that has a level 7.00 dB lower than a 4.00 × 10–9 W/m2 sound? Problem #6: What is the intensity of a sound that is 3.00 dB higher than a 4.00 × 10–9 W/m2 sound? Problem #7: If a large housefly 3.0 m away from you makes a noise of 40.0 dB, what is the noise level of 1000 flies at that distance, assuming interference has a negligible effect?A convertible moves toward you and then passes you; all the while, its loudspeakers are producing a sound. The speed of the car is a constant 13.5 m/s, and the speed of sound is 344 m/s. What is the ratio of the frequency you hear while the car is approaching to the frequency you hear while the car is moving away?The lower frequency limit of hearing for a particular human being is 25.3 Hz. What is the corresponding wavelength (in meters) for this frequency if the speed of sound in air is 343m / s ?
- Sound waves travel at roughly 340 m/s at room temperature. The minimum hearing range of a human is 20Hz. a) What is the wavelength of this wave? b) Could this wavelength fit inside the dimensions of Room 411( room dimensions are roughly 11.5 m x 8.7 m)? Justify your answer with sound reasoningIf a sound with a singular frequency of 580 has an measured intensity of 9.79 x 10-5 w when at a distance of 5.88 m from the source, what is the decibel level when at a distance of 11.9 m from the source?You are at BNA (Nashville Airport) watching commercial airliners take off. At a distance of 1,020.6 away from the plane, you record a sound intensity level of 73.4 decibels. If you move such that the new sound intensity level is 88.07 decibels, how far are you away from the plane (in meters)?
- You are at BNA (Nashville Airport) watching commercial airliners take off. At a distance of 1,364.2 away from the plane, you record a sound intensity level of 69.31 decibels. If you move such that the new sound intensity level is 91.34 decibels, how far are you away from the plane (in meters)?A speaker is talking at a distance of 3.0 m from where you are and you measure the sound intensity as 1.1x10-7 W/m². a) Another student is 4.0 m away from the speaker. What sound intensity does the other student measure? b) What is the sound intensity level in decibel for an intensity of 1.1×10-7 W/m²? (Lowest detectable intensity for human Io=10-¹2W/m²)You are trying to overhear a juicy conversation, but from your distance of 15.0 m, it sounds like only an average whisper of 20.0 dB. So you decide to move closer to give the conversation a sound level of 60.0 dB instead. How close should you come?
