Fall asleep easily, focus, or relax with brown noise, green noise, pink noise, and white noise, plus an integrated sleep timer. Features: * High-quality white noise, pink noise, green noise, and brown noise * Integrated Sleep Timer that fades out noise after a set time * Mix noise with the audio from other apps * Play on speakers, AirPods, or HomePod * Control from the lock screen * Relaxing Dark Mode * Ask Siri to "Play Noise Machine” or to play a specific noise Noise Machine is the best noise maker app! The beautiful design of this white noise maker app is a joy to use each night. Noise Machine features four “colors” of noise - each with different properties: • Brown Noise (also known as Red Noise) has a rich, deeper character with strong low frequencies and roars like a river or an ocean. Brown noise is beneficial for sleep, and even more effective when played through a powerful speaker to bring out its deep tones. Our brown noise is mathematically accurate, representing the true nature of brown noise. • Green Noise has an ambient and natural feel that gives the feeling of being in a forest or river valley. Green noise is energizing like a long walk in the woods. • Pink Noise has a more balanced texture that highlights the middle frequencies evenly, like a calming rain storm. Our pink noise is mathematically balanced. • White Noise is pure and flat with an equal balance of low, medium, and high-frequency sound. White noise may sound like a waterfall cascading down a rocky cliff. Our white noise is mathematically accurate, representing true white noise. Noise Machine now works with Siri. Say “Hey Siri, play Noise Machine” to pick right up where you left off with your favorite noise. You can also say: “Hey Siri, play brown noise on Noise Machine.” Are you often distracted by irritating sounds when trying to sleep at night, like city noise, loud traffic, the fan ticking, the neighbor’s music, or a partner snoring? Put on your sleep noise using this app, and you will soon find that distractions are no longer bothering you. You will also notice that this noise has a calming effect that helps you relax and drift off to sleep naturally. Once you have connected with the benefits of these sleep sounds, it may profoundly change the way you sleep. These noises are also very effective in focusing the mind on office work, study, or thought in distracting environments. By replacing the base volume of the background noise in the environment around you with random white noise, pink noise, or brown noise, the distracting sounds are drowned out, leaving you a soothing virtual silence. The noise-canceling sounds replace the background noise. The calming effect of the noise helps focus the mind on the task at hand, facilitating clarity and productivity. The audio from this app works great when played directly from your iPhone or iPad speaker and can also connect to headphones, AirPods, a Bluetooth speaker, HomePod, or other audio device for a louder and deeper bath of calming noise. Why buy a portable noise maker or sound machine when you can use the devices you already own! Noise Machine features a sleep timer to automatically turn off noise at night after a set time. Some people like to fall asleep by relaxing with noise, but find that they prefer the noise to fade out during sleep. Set a sleep timer to your desired time, and the noise will fade out very slowly. People use Noise Machine to: • fall asleep faster • block out distracting sounds • provide a source of background noise • increase focus and concentration • help with work and study • relax and reduce stress • increase privacy in the home or office • quiet your mind • alleviate tinnitus • calm infants, toddlers, children, and babies • drown out a snoring partner Privacy Policy: https://zipoapps.com/noisemachineios/privacy/ Terms and Conditions: https://zipoapps.com/noisemachineios/terms/
