Perfect for sleeping and for privacy purposes!
This is our third Sound conditioner purchase and not because they break down, but because we like them so much we have them in different bedrooms! I am also a therapist, and I like to have one outside of my office door so that people passing by my office door cannot hear any talking that is taking place in my office.  They are very durable.  I've had my original one for years!
