# Sound Intensity Problem of 3 Machines

• dvolpe
In summary, sound intensity is a measure of the amount of sound energy per unit area and is typically measured in decibels (dB). The sound intensity problem of 3 machines refers to the issue of determining the combined sound intensity when 3 machines are operating simultaneously in the same area or determining the individual sound intensity of each machine. Sound intensity is measured using a sound level meter, which converts sound waves into electrical signals and displays them as a sound level reading. Factors such as distance, type of sound source, and surrounding environment can affect sound intensity. The sound intensity problem of 3 machines can be solved by using mathematical equations and taking measurements at different distances and angles.

## Homework Statement

In a factory, 3 machines produce noise with intensity levels of 76 dB, 82 dB, and 85 dB. With all three running, what is the intensity level?

## Homework Equations

B = 10 log (I/Io)

## The Attempt at a Solution

B = 10 log (10e7.6 + 10e8.2 + 10e8.5)

I do not know how to evaluate this! Help please!

Solved - just plug numbers into calculator for exponents!

## 1. What is sound intensity?

Sound intensity is a measure of the amount of sound energy per unit area. It is typically measured in decibels (dB) and is used to describe the loudness or volume of a sound.

## 2. What is the sound intensity problem of 3 machines?

The sound intensity problem of 3 machines refers to the issue of determining the combined sound intensity when 3 machines are operating simultaneously in the same area. It can also refer to the problem of determining the individual sound intensity of each machine in the presence of the other two.

## 3. How is sound intensity measured?

Sound intensity is typically measured using a sound level meter, which contains a microphone that detects sound waves and converts them into electrical signals. These signals are then amplified and displayed as a sound level reading in decibels (dB).

## 4. What factors can affect sound intensity?

Several factors can affect sound intensity, including distance from the sound source, the type of sound source, and the surrounding environment. Other factors such as air temperature and humidity can also have an impact on sound intensity.

## 5. How can the sound intensity problem of 3 machines be solved?

The sound intensity problem of 3 machines can be solved by using mathematical equations to calculate the combined sound intensity or individual sound intensities. This may also involve taking measurements at different distances and angles from the machines to get more accurate results.
