Cruising with the windows down is very different from being sealed inside a car. You feel the breeze on your skin, smell the earthiness as you drive through a grove of trees, and hear the reverberation as your vehicle passes objects near the road. The steady hum of the tires on asphalt is soothing. Relax and enjoy the downtime.

The deepest, fullest Brown Noise you'll find! I took our beloved Brown Noise Sound Machine enjoyed by tens of millions of people worldwide and lowered the lows while also reducing the mids and highs. This is the gold standard for people who love deep, smooth, low soothing tones to help them sleep, study, manage their anxiety, or otherwise block out the world around them.

Our tried and true Pink Noise, beloved by 10's of millions of people around the world!
Pink Noise is a combination of White Noise and Brown Noise. They are overlaid on top of one another to gain the benefits of both the higher frequencies typically used more for sound cancellation, and the lower frequencies which tend to be more soothing for sensitive ears. Its soothing, calming, constant tones are wonderful for helping adults and babies alike to fall and stay asleep, for study, for meditation, for managing anxiety, or for any other activities where you want to block out the world and focus solely on the task at hand. It also has incredible sound masking properties for use in distracting and noisy environments!
*If you have been enjoying this Sound Machine up until now, don't fret that you see this new episode published with a more recent date! It's the same exact Sound Machine that you and millions of others have been 💤 to for years. I just republished it so that it would be at the top of the feed and remain more visible for new folks just finding the podcast!

Our tried and true White Noise, beloved by 10's of millions of people around the world!
White Noise is incredibly effective at canceling out sounds you don't want to hear...period. There is a heavier emphasis on high-end frequencies that can counteract incoming sounds and drown out the most insistent of external interruptions. My White Noise listeners may be my most passionately addicted 😄. People use this Sound Machine for all sorts of applications, but it's the gold standard when it comes to sound cancellation. Its wonderful for helping adults and babies alike to fall and stay asleep, for study, for meditation, for managing anxiety, or for any other activities where you want to block out the world and focus solely on the task at hand.

Considered the "background noise of the world", Green Noise mimics many of the sounds occurring in nature. The frequencies you hear will remind you of rushing water, or waves crashing on the beach. Green Noise falls in the middle of the frequency spectrum a bit above Brown Noise but isn't quite as high as White Noise.
It's used for many applications, but is particularly good at sound masking as well as calming anxious, running thoughts. Many of my listeners use it for sleep, while others use it to block out distractions while studying or working. Enjoy!

People use the Sound Machines for all sorts of applications but I hear most frequently from people using them to help them fall and stay asleep at home or when they travel, to help them get their baby to sleep and stay sleeping through the night, to help quiet their tinnitus, to mask unwanted noises while sleeping, traveling or studying, and to help calm their anxiety or ADHD. I have also heard from many parents who use it as ambient noise for their children on the Autism spectrum to help mask other anxiety-inducing or stressful sounds.
