“There exists no gold standard for the measurement of snoring.”
To find out, 550 representative snoring sequences, which had been recorded during polysomnography (PSG) sessions, were randomly presented to ten examiners for the evaluation of their annoyance – scored on a scale from 1 to 100 (where: 0 = no problem, 100 = excruciating). Then the mean annoyance score for each snoring sound – and the covariance parameters for the snore evaluator and snoring sounds themselves (restricted maximum likelihood method) – were calculated.
Analysis of the results showed not only that the psychoacoustic evaluation approach may indeed be a valid one, but also that “…the listeners’ noise sensitivity is at least equally relevant for the snoring annoyance as the snoring sound itself.”
