#### Goal
|
|
|
The goal is to give descriptions of the reading from the sound sensor from different distances.
|
|
|
|
|
|
### Plan
|
|
|
#### Plan
|
|
|
We will test the sensor with different loudness levels at different distances. The tone used is a 440 sinus.

#### Conclusion
|
|
|
As seen in the table, the distance of 25 cm with both 50% and 100% volume results in the same sensor reading with the value of 2. This is odd, and we are not quite sure why this.
|
|
|
In regards to the other readings the results shows a good connection with the loudness level, however, if you didn’t know the two loudness levels, it would be hard to derive their relation them from the data readings.
