Brief Summary

The purpose of this study is to evaluate the feasibility of tracking breathing during sleep with non-contact sensors (for example, microphones or wireless movement sensors). The investigators will use the data collected with these sensors to develop algorithms for tracking breathing during sleep. The investigators will assess the performance of the algorithms by comparing automatic output against manually-generated labels.

Conditions

Sleep Apnea Syndromes; Snoring

Keywords

sleep apnea; snoring

Outcome Measures

Primary Outcomes (1)

• Breathing sounds are evident in overnight audio recordings

  This study aims to track breathing during sleep using a high-quality audio interface. Our primary objective is to determine if quiet breathing sounds are visible (in the spectral domain) to trained human labelers.

  Night of recording

Study Arms (1)

At-Home

Overnight sleep at home

Eligibility Criteria

• Age: 21 Years - 89 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)

Study Population

Participants will be recruited from the PI's department (OHSU faculty, Ph.D. students) by email and the investigators' personal acquaintances. Participants must be age 21-100 and have no self-reported sleep breathing problems.

You may qualify if:

• Age 21-89
• No self-reported sleep breathing problems

You may not qualify if:

• Positive diagnosis for sleep breathing problem (e.g., obstructive sleep apnea)
