title = "Analysis of cough sound observed by different cough etiquettes",
abstract = "Several behavioural measures have been strongly encouraged by public health services to help prevent the spread of COVID-19, including safe coughing etiquette, whereby a person coughs into their elbow to prevent water droplets spreading from person to person. These new attitudes towards coughing are likely to introduce a notable change in the audio characteristics of recorded cough sounds, causing them to be {"}muffled{"}or {"}dulled{"}as the higher frequency content is attenuated. The aim of this work is to determine if cough etiquette encouraged by public health services has altered the characteristics of a cough sound in a significant manner. To determine if a significant difference exists across the cough etiquettes observed, a statistical analysis of features commonly used by state-of-the-art cough detection algorithms is presented. The features analysed are the global means of mel-frequency cepstral coefficients, zero-crossing rate, and spectral centroid. A total of 246 individual coughs were recorded and made available for public use. Results from two-tailed t-tests (significance value of 0.05) show that a significant difference exists between means in the feature sets across the cough etiquettes observed.",
