QUESTION 4 At higher intensity levels, the sound pressure level change needed to be detected O...
1. If the sound intensity of a sound wave doubles, what is the change in dB? If the sourd intensity level (in dB) increases by 5 dB, what is the change in the sound intensity? (15 pts)
• The sound level intensity is found to be 60 dB at some location. If the power of the source increases by a factor of 4, by what percent will the dB level change?
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?
When one person shouts at a football game, the sound intensity level at the center of the field is 67.3 dB. When all the people shout together, the intensity level increases to 100 dB. Assuming that each person generates the same sound intensity at the center of the field, how many people are at the game?
When one person shouts at a football game, the sound intensity level at the center of the field is 64.9 dB. When all the people shout together, the intensity level increases to 105 dB. Assuming that each person generates the same sound intensity at the center of the field, how many people are at the game?
When one viewer shouts in the Giants Stadium, the sound intensity level at the center of the field is 60 dB. When all the viewers shout together, the intensity level increases to 110 dB. Considering that each person generates the same sound intensity at the center of the field, how many viewers are at the game?
When one person shouts at a football game, the sound intensity level at the center of the field is 64.7 dB. When all the people shout together, the intensity level increases to 108 dB. Assuming that each person generates the same sound intensity at the center of the field, how many people are at the game?
please break it down step by step I'm really confused for question 4 and 2 b 1. Find the intensity level of sound with the following intensities: a) 6.84 x 10-6 W/m2 b) 45.6 x 10-14W/m2 2. Find the intensity corresponding to the following: a)-18.0 dB b) 118 dB 3. Two sounds differ in intensity levels by 105 dB. What is the ratio of the intensities of the two sounds? What sound intensity level is produced when 3 identical loudspeakers...
An acoustical Engineer was hired to make a series of sound level measurements at the site of a proposed industrial operation. The sound level meter was used to measure three levels at the same position. The engineer failed to reset the sound level meter between measurements 2 and 3 so that measurement 3 was actually the average (log mean) sound pressure level of the second and third measurements. The measurements are as follows: Lp1 = 84.0 dB Lp2 = 85.0...
Question 13 What is the sound intensity level (in units of dB) when the intensity of sound is 5.78 mW/m2?
