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 )
