sudo apt install sox
then you can run this command to play brown noise.
whats brown noise?
Also known as Brownian noise or red noise. Its power decreases by 6 dB per octave as the frequency increases. This means that as the frequency rises, the energy decreases more slowly compared to pink noise. Brown noise contains more low-frequency components than pink noise. It's often described as having a "darker" or "deeper" sound. It is often used in audio engineering, sound masking, and relaxation purposes.
other noise
you may have heard of white noise, well theres also pink noise which has all the frequencies evenly distributed. I prefer brown for masking because its less harsh on the top end and with more low end it muffles things better imo.
protip::
you can do yourself one better by making a bash script and setting an alias for it in your .bashrc file
#!/bin/bash
play -n synth brownnoise
alias noise='/home/mint/Documents/bashscripts/noise.sh'
