A member asked:

What is this airflow sound in my head and hearing my heartbeat?

A doctor has provided 1 answer

Normal blood flow.: You're probably hearing the blood flowing through blood vessels in the ear area. When you have your ear on a pillow or mattress, you're blocking out environmental noises, so the normal noises of circulation become audible.
