Table 5 Summarized results from the smartphone stethoscope apps review

From: The electronic stethoscope

References Apps name Feature highlights and characteristics Algorithms Outcome
[143] SensiCardiac Record: 15 s of HS recording at four locations
Analyze: Instantaneous classification of HS
Report: Keep record of cardiac assessment in the Cloud
HS segmentation
Time/frequency features extraction
HS signal classification using ANN
HS classified as either functional or pathological
[144] StethoCloud Cloud-based app that help diagnose pneumonia by listening to patient’s breathing sound
Noise suppression and data analysis are done in a remote server (Cloud)
Noise suppression and “deep learning algorithm” (not specifically mentioned) Diagnosis of pneumonia (and more respiratory conditions, e.g., asthma and heart failure in future)
[145] Thinklabs Record and display waveforms and spectrogram in real time
Edit sounds on-screen
Save, email recorded sounds
Does not provide HS analysis and diagnosis
NM Recorded sounds, waveforms and spectrogram
[146] Mobile Stethoscope It records body (heart, lung and bowel) sounds using built-in microphone of smartphone
It does not need external stethoscope
Record, save HS and display waveform
Does not provide HS analysis and diagnosis
NM Recorded sounds, waveforms
[147] iStethoscope Pro It amplifies and filters HS
It uses built-in microphone of smartphone
Record, save and email HS, display waveform
Does not provide HS analysis and diagnosis
HS amplification with variable gain
Low pass filtering with user selected cut-off frequency
Recorded sounds, waveforms and spectrogram
