Computerized Lung Sound Analysis

Study Purpose

This clinical trial is conducted within the research project 'Computerized Lung Sound Analysis'. The research goal is the development of a system enabling the automatic classification of lung sounds, which will result in a decision support system for physicians. The objective of this trial is to create a small lung sound corpus, enabling the development of a prototype of the described system. Therefore, investigators record lung sounds with several lung sound transducers distributed on the posterior chest of human test subjects.

Recruitment Criteria

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Accepts Healthy Volunteers
Yes

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

Trial ID:
NCT02771184

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

In this clinical trial investigators record lung sounds over the posterior chest of human test subjects. The subjects are either lung-healthy (control group) or subjects with pneumothorax condition or pulmonary fibrosis. The lung sounds are recorded in supine position on an examination table. A foam pad with several lung sound transducers is placed under the back of the subjects. During the recording the subjects wear a nose clip and hold a pneumotachograph with both hands. The subjects are instructed to breath at a certain airflow rate during inspiration, with natural breathing during expiration. For each subject investigators simultaneously record 30 seconds of the airflow signal and the lung sounds from 16 lung sound transducers.
