Sounds of valves in heating systems for classification and condition monitoring

Dataset contains 427 sounds of valves installed and operating in district heating systems.

Tables in Excel and Matlab format contain categories for each sound as follows:
1) FlowNoise, 2) Rattling, 3) Whistling, 4) Cavitation.

'FlowNoise' class corresponds to normal valve operation.
The other three classes correspond to unwanted operating conditions.

Attached Matlab table contains also 65 extracted features (acoustic features and statistical features) for each sound.

The dataset was prepared to train machine learning classifiers to classify sounds into corresponding categories.
