SnoreSounds

The SnoreSounds device aims to monitor breathing frequency by utilizing acoustic analysis of sounds, presumably snoring, to quantify respiratory rates. Its methodology involves non-invasive sound detection and signal processing to provide insights into sleep-related respiratory patterns.

The SnoreSounds device, developed by Appian Medical, Inc., is designated under product code MNR and regulation 21 CFR 868.2375 as a 'Breathing Frequency Monitor'. Its primary purpose, inferred from its trade name and regulatory classification, is to measure an individual's rate of breathing, likely by focusing on the acoustic properties of snores. The methodology presumably involves capturing sounds produced during sleep and processing these auditory signals to quantify the frequency of respiratory cycles. As a non-invasive monitoring tool, SnoreSounds likely operates by employing specific sound detection technology and analytical algorithms to distinguish relevant respiratory sounds from background noise. While the specific scientific principles of its sound differentiation or the full scope of its analytical capabilities are not detailed in this document, its function as a breathing frequency monitor suggests a science based on bioacoustic signal processing to provide data on respiratory patterns, particularly those associated with snoring during sleep.
