Hearing damage may occur when a person is exposed to a sound intensity level of 90.0 dB (relative to the threshold of human hearing) for a period of 9.00 hours. An eardrum has an area of 3.42 x 10-4 m2. How much sound energy is incident on the eardrum during this time?
Hearing damage may occur when a person is exposed to a sound intensity level of 90.0 dB (relative to the threshold of human hearing) for a period of 9.00 hours. An eardrum has an area of 3.73 x 10-4 m2. How much sound energy is incident on the eardrum during this time? Number Units
An 9 hour exposure to a sound intensity level of 90.0 dB may cause hearing damage. What energy in joules falls on a 0.800 cm diameter eardrum so exposed?
An 9 hour exposure to a sound intensity level of 95.0 dB may cause hearing damage. What energy in joules falls on a 0.700 cm diameter eardrum so exposed?
An 9 hour exposure to a sound intensity level of 95.0 dB may cause hearing damage. What energy in joules falls on a 0.750 cm diameter eardrum so exposed?
An 8 hour exposure to a sound intensity level of 90.0 dB may cause hearing damage. What energy in joules falls on a 0.500 cm diameter eardrum so exposed? ________J
A sound wave with intensity 2 × 10-3 W / m^2 is considered as moderately loud to our ears. The drum inside our ear has a diameter of 6 mm. Show that the energy transferred to the drum of our ear if you hear the above sound wave for 60 seconds is E = 3.4 × 10-6 J. Consider the drum as a round surface.
Prof. Bohn Worksheet 12.1 At a busy street corner, the sound level is 75 dB. What is the intensity of sound there? 1. 2. A trumpeter plays with a sound level of 72 dB. Three equally loud trumpeters join in. What is the new sound level?
Sound Intensity & dB: You are watching the space shuttle rise after it launches. The sound level of the shuttle is 170 dB at a distance of 10.0m from the engine flames. Your seat in the bleachers is 10.00 km away. 25. What is the sound level at your ear (in dB)? Note: Pay attention to the units required for the answer.

Using a frequency-measuring lab device, I am to map out the sound intensity level distribution (dB) in a room (both with & without music playing) to create a 5x5 grid of 25 data points. Using the following data table of sound intensity level β(dB) and corresponding intensity I(W/m2), I also need to find the intensity to the nearest order of magnitude for the points on my sound intensity level maps. Here is the data table: Intensity levelβ(dB) Intensity I(W/m2) Example/effect...
