## 3 Tests and Results
### Skill Performance Tests with Sound Disturbances  
As in the previous case, the same test protocol is performed with a single user. Still, disturbance sounds are added near the voice assistant to simulate noise from the industrial environment. The decibel level generated by the disturbances was 84 dB. Table 3 shows the results obtained. \begin{table}
