Brown Earth Rumble
Brown Earth Rumble is a deep rumble you feel more than hear, closer to a lorry idling outside than to anything hissy. It is the darkest recording in the noise set on this site. Whether you get much of it at all depends entirely on what you play it through.
Ready to play
Stack this under rain or a fire, keep the blend, and play it with your screen off. Slo, on iOS, Android and Mac.
Your speaker decides what you get
Laptops, phones and most small Bluetooth boxes give up somewhere around the bottom of a man's voice. Three-quarters of this file lives below that line. On a laptop it thins out to a hum with the substance stripped off, and turning it up mostly raises the part you were not interested in. On headphones, or a speaker with a real driver in it, it is the heaviest thing on the site.
A slow swell runs through it, roughly one a second, so it breathes rather than sitting still. The two channels are identical, which means there is no stereo spread to go looking for. What headphones give you here is the bottom of the range, not width.
The wall problem
Low frequencies pass through building structure far better than high ones. If your reason for playing noise is a shared wall, this is the file most likely to travel back the other way, and a level that feels moderate at your desk can be plainly audible next door. For voices specifically, a bed sitting in the speech range covers them better anyway. White Snow Blanket and Green Forest Whisper are both built that way.
For the same family with more middle left in it, Deep Brown Noise is warmer and Slow Brown Noise sits between the two. The live brown noise generator gives you the character without a repeat, since it makes new sound continuously rather than looping a recording. To add detail over the rumble without losing it, try the Brown Earth Rumble and gentle rain blend in the free sound mixer.
Frequently asked questions
Why does it sound thin on my laptop?
Because most of the file sits below what a small speaker can produce. You are hearing the fraction that survives, not the rumble itself.
Is it a good choice against noisy neighbours?
Not the best one. Bass travels through walls in both directions, and voices sit higher up. A midrange-heavy file such as White Snow Blanket covers speech more efficiently.
Does it use stereo?
No. The two channels are identical, so it is mono however you play it.
How long is the loop?
Thirty-two seconds, repeating until you stop it or the sleep timer does.
