| Name | Value | Explanation | Source |
| Microphone array range | 10x10 meter | Range provided by manufacturer | [1] |
| Microphone mounting height | 2.5 meters | Minimum mounting height provided by manufacturer | [1] |
| Distance between detection device and measurement station | 2 meters | Preferred value | |
| Percentage of infected people | 0.1% | This is the amount of people currently tested positive for COVID-19. Some of these people are in the hospital and do not count, also the people tested positive will be a lot more careful coming into contact with others. However there are also people that have COVID-19 that are not tested. This will even out and so the same percentage of infected people was taken. | [2] |
| Chance of detecting a cough with camera and microphone | 87% | Chance obtained by Korean researchers using a similar system | [3] |
| Time spent at measurement station per person | 4 minutes | 1 minute testing + 2 minutes disinfecting + 1 spare minute | |
| Expected false positive rate in measurement station | 7% | Study of similar cough classification algorithm achieved 96.6% accuracy. In this specific case this becomes higher than only the cough test since only 1 test needs to be positive to refuse access | [4] |
| Expected false negative rate in measurement station | 7% | Study of similar cough classification algorithm achieved 96.6% accuracy. In this specific case this becomes higher than only the cough test since only 1 test needs to be positive to refuse access | [4] |
| Frequency of random person getting picked out | After every 2 coughing persons detected, 1 person is picked out randomly, if there is no queue | This will ensure random people are not picked too often/not often enough and also random persons will not have to wait in a queue | |
| Chance a healthy person coughs when in range of the microhpone | 0.08% | Based on average cough time and walking speed | [5] |
| Estimate of cost of the total system | €10950,- | : €5500 for thermal camera, €1000 for microphones, €100 for microphone in cabin, €400 for camera on pole, €750 for camera pole, €3000 for booth including computer, software, screens, and interfaces, €200 for UV light | Various webshops |
| Salary of medical personnel | €25 per hour | Obtained from dad of group member who is a salary administrator | |
| Dutch reproduction rate of COVID-19 | 3 | [6] | |
| Number of people in half an hour entering Heuvel Galerie during a quiet hour at a quiet entrance | 24 | Counted by group members | |
| Number of people in half an hour entering Heuvel Galerie during a quiet hour at a busy entrance | 61 | Counted by group members | |
| Number of people in half an hour entering Heuvel Galerie during a medium busy hour at a quiet entrance | 117 | Counted by group members | |
| Number of people in half an hour entering Heuvel Galerie during a medium busy hour at a busy entrance | 194 | Counted by group members | |
| Number of people in half an hour entering Heuvel Galerie during a busy hour at a quiet entrance | 233 | Counted by group members | |
| Number of people in half an hour entering Heuvel Galerie during a busy hour at a busy entrance | 756 | Counted by group members |
