Brown Noise Timer
01:30:00
Brown noise is a type of sound signal that has a power spectral density inversely proportional to f². It's deeper than white noise and can help with focus and relaxation.
Click on the time display to set your desired duration, then press Start. The brown noise will play until the timer reaches zero.
Some browsers have strict autoplay policies that may interrupt audio playback. If the sound stops, try clicking the Start button again. For the best experience, make sure your browser allows audio autoplay for this site.
Brown noise is generally safe to listen to for extended periods at a reasonable volume. However, like any audio, it's recommended to follow the 60/60 rule: listen at no more than 60% volume for no longer than 60 minutes at a time.
Brown noise has a deeper, richer quality compared to white or pink noise. Its lower frequency profile is often described as more soothing and less harsh, making it particularly effective for focus and relaxation. Many people find it reminiscent of natural sounds like ocean waves or steady rainfall.
Yes, you can use this timer for sleep. Set your desired duration and the brown noise will automatically stop when the timer ends. However, keep in mind that your device needs to stay awake for the audio to continue playing.
This depends on your device and browser settings. On most mobile devices, locking the screen will pause the audio. For uninterrupted playback, keep your device unlocked or adjust your device settings to allow background audio playback.
Once you've loaded the page, the timer functionality will work offline. However, you'll need an internet connection to initially load the brown noise audio file.
The alarm is designed to be noticeable but not jarring. However, its effectiveness as a wake-up alarm depends on your sleep depth and volume settings. For important wake-up alarms, we recommend using a dedicated alarm clock or phone alarm.
While white noise contains all frequencies with equal power, and pink noise reduces high frequencies, brown noise reduces high frequencies even more dramatically. This creates a deeper, bassier sound that many find less fatiguing over long periods. Unlike nature sounds or music, it's consistent and non-distracting.
