On a good night, the front row of the Twisted Sister concert would surely result in a 120 dB sound level. A Walkman produces 100 dB. How many Walkmans would be needed to produce the same intensity as the front row of the Twisted Sister concert?

100

To determine the number of Walkmans needed to produce the same intensity as the front row of the Twisted Sister concert, we need to compare the sound levels of both.

Given information:
Twisted Sister concert level: 120 dB
Walkman level: 100 dB

The decibel scale is logarithmic, which means that every 10 dB increase represents a tenfold increase in sound intensity. In other words, an increase of 10 dB means the sound intensity is multiplied by 10.

To calculate how many Walkmans are needed to reach the same intensity as the front row of the Twisted Sister concert, we can use the following formula:

Number of Walkmans = 10 raised to (difference in decibel levels / 10)

In this case, the difference in decibel levels is 120 dB - 100 dB = 20 dB. Thus, the formula becomes:

Number of Walkmans = 10^(20 dB / 10)

Simplifying the equation,
Number of Walkmans = 10^2
Number of Walkmans = 100

Therefore, you would need 100 Walkmans to produce the same intensity as the front row of the Twisted Sister concert.
