White Silence is to the Deaf what white noise is to the hearing, both are aids get helps us sleep well through the nights without disruptions. White noise blocks out noises that awaken the hearing people, like dripping faucet, airplane flying overhead, sirens on the streets, and teenagers chatting all night, etc. White Silence, is the same, only that a soothing bed vibration blocks out the vibrations that disturbs our sleep. As for myself, I uses Silence Noise so I won't be awaken by my son playing the drum in the garage, a garbage truck banging the dumpster at my apartments, Deaf cultists knocking on my door and the trains passing through, etc.

One day took a Soviet era Lada taxi to outskirts of Havana to visit a Deaf school. They asked me what we Deaf Americans do with our obsolete TTY as we are using VP nowadays, hopefully some organizations will donate those equipment. I felt like was blasted into the past, surrounded by all those vintage automobiles.
