	Acoustic Waveform Airway and Respiratory Examination (AWARE/PTEase) Dataset
	===================================================================================================

	Guidelines
	===================================================================================================
	AWARE/PTEase is a smartphone-based sensing system that examines human airway's internal physiological conditions, developed by the Intelligent Systems Laboratory at University of Pittsburgh. AWARE/PTEase probes the airway with acoustic pulses through mouth, and collect the airway's reflections for analysis. Please refer to [our paper](https://doi.org/10.1145/3581791.3596854) and [github repo](https://github.com/pittisl/PTEase) for more details.

	This dataset includes the raw and pre-processed acoustic data of airway measurements collected from 382 human subjects recruited at the Children’s Hospital of Pittsburgh. Demographics of the recruited human subjects are as follows：
	\| Category \| Characteristics \| Number \|
	\|--------------------\|----------------------\|----------------\|
	\| Demographics \| Age (years) \| 22.55 ± 15.63 \|
	\| \| Adults (%) \| 166 (43.46) \|
	\| \| Female (%) \| 205 (53.66) \|
	\| \| Caucasian (%) \| 287 (75.13) \|
	\| \| African-American (%) \| 93 (24.35) \|
	\| Body Conditions \| Height (cm) \| 159.76 ± 15.67 \|
	\| \| Weight (kg) \| 65.79 ± 27.28 \|
	\| Disease Conditions \| Healthy (%) \| 115 (30.10) \|
	\| \| Asthma (%) \| 190 (49.74) \|
	\| \| Cystic Fibrosis (%) \| 64 (16.75) \|
	\| \| COPD (%) \| 8 (2.09) \|
	\| \| Others (%) \| 5 (1.31) \|

	The contents of this dataset include three parts:

	- Raw WAV files

	- "aware_raw.zip"

	- 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.


	- Segmented and aligned acoustic pulses

	- "aware_segmented.pkl"

	- Python pandas.DataFrame saved as a PICKLE file. Same contents as "aware_segmented.csv", but without flattening.

	- To load the data, use the following commands:

	``` python
	import pandas as pd
	df = pd.read_pickle("aware_segmented.pkl")
	```
	- Column 0-45 : Basic subject information, including demographics, clinical measurements and labels.
	- Column 0 : Subject ID
	- Column 1-9 : Demographics
	- Column 10 : Disease label
	- Column 11-21 : Impulse Oscillometry Measurements
	- Column 22-30 : Spirometry measurements
	- Column 31-44 : Spirometry measurements in post-bronchodilator test
	- Column 45 : Test number

	- Column 46-55 : 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 lasts for 0.1 sec (4800 sample points).
	- Column 46 : Phase "Calibration #1". Each element is a [12,4800] NumPy ndarray
	- Column 47 : Phase "Calibration #2". Each element is a [12,4800] NumPy ndarray
	- Column 48 : Phase "Calibration #3". Each element is a [12,4800] NumPy ndarray
	- Column 49 : Phase "Nasal breathing". Each element is a [25,4800] NumPy ndarray
	- Column 50 : Phase "Inhale #1". Each element is a [25,4800] NumPy ndarray
	- Column 51 : Phase "Inhale #2". Each element is a [25,4800] NumPy ndarray
	- Column 52 : Phase "Inhale #3". Each element is a [25,4800] NumPy ndarray
	- Column 53 : Phase "Exhale #1". Each element is a [25,4800] NumPy ndarray
	- Column 54 : Phase "Exhale #2". Each element is a [25,4800] NumPy ndarray
	- Column 55 : Phase "Exhale #3". Each element is a [25,4800] NumPy ndarray

	- "aware_segmented.csv" and "headers.txt"

	- NOTE: Directly loading this CSV file is not recommended. It could be time-consuming and buggy. Try "aware_segmented.pkl" first.

	- NOTE: "aware_segmented.csv" has no headers. See column definition below.

	- Column 0-45 : Basic subject information, including demographics, clinical measurements and labels.
	- Column 0 : Subject ID
	- Column 1-9 : Demographics
	- Column 10 : Disease label

	- Column 45 : Test number

	- Column 46-1012845 : 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 lasts for 0.1 sec (4800 sample points).

	- Processed airway cross-sectional area (CSA) curves inferred from the acoustic signals

	- "aware_csa.csv"

	- NOTE: Not all raw samples are used for airway CSA reconstructions. Low-quality data is discarded, thus the sample size of this part is smaller than above

	- Column 0-45 : Basic subject information. Same as "aware_segmented.csv".

	- Column 46-129: Reconstructed airway cross-sectional area at different depths from mouth.
