“How reliable is the data logging function?”
Data logging is used to compare the patients’ testimonials about how often they used their hearing aids. In addition, the hearing aid acoustician can compare how long and in which acoustic environments the patients wore their hearing aids. The hearing aid users’ statements often deviate from the information gained from data logging. This raises the question of whether and when complications can occur in the recording of wearing behaviour.
A study conducted at Aalen University examined the reliability of data logging and the factors that can affect it. In addition to the duration of the logging, the situation detection for three different manufacturers was also investigated. Different acoustic situations were designed using eight loudspeakers while the duration of measurement was three and eight hours.
The results show that the documentation of the overall wearing time is very reliable, while reliability for detecting the hearing environment depends on the situation and manufacturer.
