Sleep Apnea vs Snoring: What Is OSA?

Snoring is a sound; obstructive sleep apnea (OSA) involves repeated upper-airway blockage during sleep. Sound alone cannot tell them apart. SomniSense, a sleep apnea detector app, marks candidate breathing pauses so you can review their estimated timing, waveform and surrounding sounds; it cannot diagnose or screen for OSA. Discuss witnessed pauses or gasping with a clinician without waiting for an app result.

For a clinical answer, discuss your symptoms and history with a qualified clinician. Sleep apnea is evaluated with appropriate testing; obstructive and central forms involve different mechanisms that a phone microphone cannot distinguish.

Common symptoms are worth discussing, but they are not specific

The U.S. National Heart, Lung, and Blood Institute lists symptoms that may occur with sleep apnea, including frequent loud snoring, breathing that starts and stops, gasping, daytime sleepiness or tiredness, focus problems, and headache. Other conditions and circumstances can produce overlapping symptoms.

Recurring gasping, witnessed pauses, persistent tiredness, or another concern can be a reason to speak with a qualified clinician regardless of what a consumer app reports.

What clinical testing adds

Clinical pathways can measure signals such as airflow, oxygen saturation, respiratory effort, sleep state, heart activity, and movement, depending on the test. A professional interprets those signals alongside symptoms and history.

Cost, scheduling, insurance, availability, and timing vary by location and care pathway. That variability does not reduce the clinical authority of the test.

What your own phone can help you check

You can keep a record of the breathing sounds around a marked moment, rather than relying only on how you feel in the morning. SomniSense’s own audio analysis organizes possible pauses and shallow-breathing patterns on your compatible phone. Open a mark, check its estimated time and waveform, and listen to the available sound before and after it. You can save available minute audio for your own records.

One completed report is enough to begin. If you choose to record more nights, you can look for recurring observations and keep them together in a structured wellness report. That adds context, not a diagnosis; BRI is not clinical AHI.

Questions behind this search

Apnea and hypopnea: what is the difference?

Clinically, apnea means airflow stops or nearly stops; hypopnea is reduced airflow assessed with accompanying physiological criteria. A quieter sound is not enough to classify either. Phone candidates are not these clinical events.
