Acoustic Waveform Airway and Respiratory Examination (AWARE/PTEase) Dataset
===================================================================================================
Guidelines
===================================================================================================
AWARE/PTEase is a smartphone-based sensing system designed to examine human airway's internal physiological conditions. AWARE/PTEase probes the airway with acoustic pulses through mouth, and collect the airway's reflections for analysis. Please refer to our paper[1,2] for more details.
This dataset includes the raw and pre-processed acoustic data, arranged in 3 parts:
- "aware_raw": Raw .wav files
- Subfolders are named by the subjects' ID (from 1 to 382)
- In each subfolder, there are three "cali_X.wav" files and multiple "test_X.wav" files
- "cali_1.wav" : Calibration step 1 - long tube calibration - consists of 12 pairs of received pulses. Each pair contains one wide-band (0-16Hz) pulse and one narrow-band (0-200Hz) pulse. The narrow-band pulses are deperacated and only the wide-band pulses are used. Transmitting period for each pair is 0.4 sec.
- "cali_2.wav" : Calibration step 2 - standard tube close-end calibration - is the same as above except the calibrations are conducted in a different setting.
- "cali_3.wav" : Calibration step 3 - standard tube open-end calibration - is the same as above except the calibrations are conducted in a different setting.
- "test_X.wav" : Test number X - the subject's X-th attempt of conducting the test - follows the protocol of "Nasal breathing -> Inhale -> Exhale -> Inhale -> Exhale -> Inhale -> Exhale". Each segment contains 25 pulses collected at an interval of 0.2 sec. NOTE: Some of the samples have 50 pulses for the "Nasal breathing" phase.
- "aware_segmented": Segmented and aligned acoustic pulses
- "aware_segmented.csv" and "headers.txt"
- Column 1-46 : Basic subject information, including demographics, clinical measurements and labels. See "headers.txt".
- Column 1 : Subject ID
- Column 2-10 : Demographics
- Column 11 : Disease label
- Column 12-22 : Impulse Oscillometry Measurements
- Column 23-31 : Spirometry measurements
- Column 32-45 : Spirometry measurements in post-bronchodilator test
- Column 46 : Test number
- Column 47-1012846 : Acoustic signals (16-bit PCM, sample rate = 48000). Arranged by different phases. Each calibration phase contains 12 measurements and each testing phase contains 25 measurements. Each measurement last for 0.1 sec (4800 sample points).
- Column 47-57646 : Phase "Calibration #1". Flattend from [12,4800] by row-major order.
- Column 57647-115246 : Phase "Calibration #2". Flattend from [12,4800] by row-major order.
- Column 115247-172846 : Phase "Calibration #3". Flattend from [12,4800] by row-major order.
- Column 172847-292846 : Phase "Nasal breathing". Flattend from [25,4800] by row-major order.
- Column 292847-412846 : Phase "Inhale #1". Flattend from [25,4800] by row-major order.
- Column 412847-532846 : Phase "Inhale #2". Flattend from [25,4800] by row-major order.
- Column 532847-652846 : Phase "Inhale #3". Flattend from [25,4800] by row-major order.
- Column 652847-772846 : Phase "Exhale #1". Flattend from [25,4800] by row-major order.
- Column 772847-892846 : Phase "Exhale #2". Flattend from [25,4800] by row-major order.
- Column 892847-1012846 : Phase "Exhale #3". Flattend from [25,4800] by row-major order.
- "aware_segmented.pkl"
- Python pandas.DataFrame saved as pickle file. Same contents as "aware_segmented.csv", but without flattening.
- To load the data, use the following commends:
``` python
import pandas as pd
df = pd.read_pickle("aware_segmented.pkl")
```
- "aware_csa": Processed airway cross-sectional area (CSA) curves infered from the acoustic signals
- NOTE: Not all raw samples are used for airway CSA reconsturctions. Low-quality data is discarded, thus the sample size of this part is smaller than above
- "aware_csa.csv" and "headers.txt"
Column 1-46 : Basic subject information. Same as "aware_segmented.csv". See "headers.txt".
Column 47-130: Reconstructed airway cross-sectional area at different depth from mouth.
