Respiratory diseases cause loss of productivity in pig houses. Cough is element for diagnosis. Acoustic features like Root Mean Square (RMS), peak frequency [Hz] and duration, of cough sounds from Pasteurellosis pneumonia infection (S) are compared with healthy cough from inhalation of citric acid (H).There is no difference in the RMS value. H mean peak frequency is 1178 Hz, S is 500 Hz (P<0.004). Duration shows lower values (P<0.0001) for H (μ: 0.25 seconds) than for S (μ: 0.30 seconds). Time among S: 0.37 s seems shorter than among H 0.52 s. Sound analysis provides physic acoustic features that can be used as tool to detect and label cough in a automatic monitoring system applied in farms.Respiratory diseases cause loss of productivity in pig houses.

Abstract
Respiratory diseases cause loss of productivity in pig houses. Cough is element for diagnosis. Acoustic features like Root Mean Square (RMS), peak frequency [Hz] and duration, of cough sounds from Pasteurellosis pneumonia infection (S) are compared with healthy cough from inhalation of citric acid (H).There is no difference in the RMS value. H mean peak frequency is 1178 Hz, S is 500 Hz (P<0.004). Duration shows lower values (P<0.0001) for H (μ: 0.25 seconds) than for S (μ: 0.30 seconds). Time among S: 0.37 s seems shorter than among H 0.52 s. Sound analysis provides physic acoustic features that can be used as tool to detect and label cough in a automatic monitoring system applied in farms.Respiratory diseases cause loss of productivity in pig houses.
