The two fans create the noise…From the Widex product description:
To maintain your ear health and optimal performance of your quality Widex hearing aids we recommend the use of the Widex Charge n Clean Charger. It performs the following three functions:

  1. Charging: A constant temperature is maintained throughout the charging process for optimal battery performance. A 4 hour charge will give more than a fulls day wear time and a quick 30 minute charge provides 4 hours of wear time.
  2. Cleans: Six LED’s that emit a UV-C light have a germicidal property helping sterilise your hearing aids. Widex claims it kills up to 99.9% of bacteria, yeast and viruses.
  3. Active Drying: The device circulates warm air using two fans and a heating device to dehumidify the hearing aids in a controlled manner.
