hi, i'm a new comer. Shannon, i'd like to ask a few question regarding playing ultrasonic track on speakers while i sleep at night. but instead a a quite night, i sleep near factory environment. my room's noise at night is around 50-70 db.
My question is:
1. is it still effective playing silent track using speaker while i sleep in noisy bedroom?
2. do i need to increase volume setting for the silent track?
3. this week, i wake up every 2 hours listening to trickling stream using earbud while sleeping. is it normal?
i really apprecite if the is a solution to my problem. thx
