For me, to have a productive environment for my mental health, I must have sound as the top priority before visual, touch, smell or taste.  I find my emotions connect with sound, such as music or birds, waves etc.  

When I was young, I used to run around in the local bush a lot, and I have fond memories of listening to the magpies sing, the crows yelling for mark or budgies chirping.  

I find visuals or smell at around the same level but i can tolerate a 70's kitchen if the music that gets my toes tapping is being played.  A lack of sound or industrial sounds like cars, machinery, planes or helicopters may not be in front of my brain, but I have recently discovered that this upsets my subconscious more and this leads to anxiety as my brain tries to cope with all these unnatural and disturbing sounds. 

I don't have many memories from being young around cooking so certain cooking smells don't put me at ease.. it definitely sound that centers me.
