Brown noise + heartbeat sounds for sleep and deep relaxation.

The heartbeat sound starts at 60 BPM (beats per minute) and gradually reduces to 50 BPM at the one-hour mark, a good and expected heartbeat range for people while sleeping.

Brown noise can be very calming, as it can sound a bit like a waterfall or rain. With this brown noise track, I’ve added a filter to the sound, which creates an effect that sounds a lot like rushing wind.

Brown noise can be helpful for sleep, insomnia, deep relaxation, and even reducing tinnitus symptoms.

How Does Brown Noise Differ from White and Pink Noise?

White Noise: Sounds like TV static. It uses a random mix of high and low frequencies across the spectrum.
Pink Noise: The higher frequencies are not as loud, so pink noise is generally more pleasant than white noise.
Brown Noise: This uses primarily lower frequencies and is the most soothing sound of the 3.
