abstract = {In the past few decades, analysis of heart sound signals (i.e. the phonocardiogram or PCG), especially for automated heart sound segmentation and classification, has been widely studied and has been reported to have the potential value to detect pathology accurately in clinical applications. However, comparative analyses of algorithms in the literature have been hindered by the lack of high-quality, rigorously validated, and standardized open databases of heart sound recordings. This paper describes a public heart sound database, assembled for an international competition, the PhysioNet/Computing in Cardiology (CinC) Challenge 2016. The archive comprises nine different heart sound databases sourced from multiple research groups around the world. It includes 2435 heart sound recordings in total collected from 1297 healthy subjects and patients with a variety of conditions, including heart valve disease and coronary artery disease. The recordings were collected from a variety of clinical or nonclinical (such as in-home visits) environments and equipment. The length of recording varied from several seconds to several minutes. This article reports detailed information about the subjects/patients including demographics (number, age, gender), recordings (number, location, state and time length), associated synchronously recorded signals, sampling frequency and sensor type used. We also provide a brief summary of the commonly used heart sound segmentation and classification methods, including open source code provided concurrently for the Challenge. A description of the PhysioNet/CinC Challenge 2016, including the main aims, the training and test sets, the hand corrected annotations for different heart sound states, the scoring mechanism, and associated open source code are provided. In addition, several potential benefits from the public heart sound database are discussed.},

Introduction
The Shiraz University (SU) fetal heart sounds database (SUFHSDB) contains fetal and maternal PCG recordings from 109 pregnant women.
Data Collection
This database was constructed using recordings made from 109 pregnant women (mothers aged from 16 to 47 years, mean±SD: 29.3±5.8 years with BMI from 19.5 to 38.9 mean±SD: 29.2±4.0), with a digital JABES Electronic stethoscope (GS Technology Co. Ltd., South Korea) placed on the lower maternal abdomen as described in (Samieinasab and Sameni, 2015).
In the case of twins (seven cases) the data were collected twice according to the locations advised by the expert gynecologist. Audacity® cross-platform audio software was used for recording and editing the signals on a PC. In total, 99 subjects had one signal recorded, three subjects had two and seven cases of twins were recorded individually, resulting in 119 total recordings. The average duration of each record is about 90 seconds. The sampling rate was generally 16,000 Hz with 16-bit quantization and a few recordings at 44,100 Hz. The data was recorded in wide-band mode of the digital stethoscope, with a frequency response of 20 Hz to 1 kHz.
In most cases (91 subjects), the heart sounds of the mothers were also recorded before each fetal PCG recording session. As a result, a total number of 92 maternal heart sounds data (90 subjects had one heart sound signal but one had two signals recorded) are also available in the dataset.
Files
The record names are in the form fSS or mSS where f stands for fetal recording, m stands for maternal recording, and SS is the subject number. There are also WFDB headers provided to read the data using WFDB format.
Contributors
The SUFHSDB was provided by Dr. Reza Sameni from Shiraz University. The datasets were recorded as part of the Master's thesis of Ms. Maryam Samieinasab at Shiraz University.

The authors would like to thank Dr. M. Hosseiniasl and Ms. Nasihatkon from Shiraz Hafez Hospital, for their valuable assistance during fetal PCG recordings.
