Exactly "At the beginning of the experiment, the typical headset had 60 microorganisms on its surface; after an hour's use of the headphones by a volunteer, that number went up to 650 - roughly 11, not 700, times more.

This depends on the bacteria - some bacteria have generation times of less than an hour while other bacteria species have generation times of weeks or months.

The bacteria population has an exponential growth with a factor of 16 per hour. The growth factor has to be determined for the population change each half hour.
