Hi, chrisfish! Everyone is so different when it comes to migraine triggers. Some people need absolute silence, others like you need a little noise. I know that those members who do like background sounds have different tastes and triggers -- we have people who prefer soft, soothing music and even those who want hard rock during an attack!
Have you experimented with different kinds of "color" noises? For example, brown noise is a lower frequency and pitch, while pink noise is a bit higher. Maybe one of those will be a better fit for you.
I hope some of this is helpful to you. Take good care of yourself! -Melissa, migraine.com team
