Abstract
A hearing aid (1) and a method of managing data stored in a logging device in a hearing aid is devised. The method involves obtaining sets of data representing parameters such as the sound environment at a predetermined data acquisition rate and storing the data according to one of a plurality of a set of possible parameter sets in a histogram (15) is having room for a limited number of instances of each particular set of parameters. If the limit for a particular histogram bin is reached when an instance is stored in the histogram, the data acquisition rate is adjusted according to a specified scheme and the number of instances of every parameter set is reduced by a fixed factor. Acquired data in the histogram thus reflects the most recent sound environments experienced by the hearing aid user.
