The aim of this study was to compare the snoring sounds induced during sleep nasendoscopy, and to compare them with those of natural sleep using sound frequency spectra. The snoring of 16 subjects was digitally recorded during natural and induced sleep, noting the site of vibration during sleep nasendoscopy. Patients with palatal snoring during sleep… (More)
Different methods are used for quantifying coughing in sound recordings, but as yet no method has been shown to be more valid than any other. In the present study, the relationships between three different units of cough were examined and their ability to predict subjective ratings of cough and cough-related quality of life were evaluated. In total, 70… (More)

Objective cough monitoring is an important development in the assessment of cough, but it is technically challenging. It is essential that systems designed to automatically detect cough are carefully validated. The recent study by BIRRING et al.  reports ''the validation of the LCM and preliminary findings of 6-and 24-h recordings in patients with… (More)
It has been shown that computerized sound frequency analysis can be used to distinguish between different snoring sites. The aim of this study was to investigate whether a portable recording method using audiotapes and digital minidisc formats could produce waveforms similar to a computer recording. The snores of 12 subjects in their natural sleep were… (More)
