The threshold in quiet is highly reproducible for individual subjects

Evidence

The threshold in quiet indicates a.<-; a function of frequency the sound pressure level of a pure tone that is just audible. This threshold can be measured quite easily by experienced or inexperienced subjects. The reproducibility of the threshold in quiet for a single subject is high and lies normally within ±3dB. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing.
