Aims
- Measurement of power consumption of devices
- Measurement of noise emission sound distribution
Material
Quality slide - 40x (Tissue area: 2,6153 cm²)
Acoustic Camera
Acoustic Camera
- phased array of 48 microphones
- fine spectral and time resolution (down to 10 µs)
Energy Meter
- in-socket device
- ±1%, ±1W typical
General Conditions
- All participants had to scan the same slides – no separate scanning
- Scanning system only (without computer and monitor)
- Measuring in parallel
Evaluation
- Determination of energy / tissue area
- Wmin, Wmax, Wh/scan
- Avg. acoustic pressure (d = 0.75m, t = 50s )
