The sound intensity from a jackhammer breaking concrete is at a distance of 2m from the point of impact. This is sufficiently loud to cause permanent hearing damage if the operator doesn't wear ear protection.what is the sound intensity an intensity level for a person watching from 50 m away?
Picnickers see a lightning flash and hear the resulting thunder 8.5s later. If the storm is traveling at a rate of 19 km/h, how long,in minutes, do the picnickers have before the storm arrives attheir location? (Enter your answer to the nearest minute.)A loud speaker has an input of 70. dB. If the volume of the soundis turned up so that the output intensity is 1,000 times greater,what is the new sound intensity level? in dBA new jackhammer has a 1/10,000 reduction in sound intensity levelfrom that of the older model that was rated at 111 dB. What is thesound intensity level of the new hammer? in dBAn average factory has a sound intensity level of 80 dB, and a rockband has a sound intensity level of 110 dB. How many times greateris the sound intensity of the band than that of the factory?
