I live on a main road with constant traffic zooming past at all hours of the day and night. I do not sleep well. I am angry, discombobulated and generally a grumpy old man.
I tried headphones, noise cancelling headphones, wax ear plugs, silicon earplugs and good old fashioned builders ear plugs. None of these worked for me. You just cannot sleep in headphones unless you are a 16 year old gamer who falls asleep at 03:00am.
I looked into what Autistic people use to reduce or remove loud noise from their lives.
My friend who has two autistic children recommended ear loops. I looked into them, ordered them and have not looked back. I wear them all the time.
I am surprised that I actually enjoy taking them off to bask in the world of noise but I do not want noise intruding into my peaceful and quiet mind.
